1.Purpose & Scope
This document provides operational and installation information on SeeRoad, a
recognition system for roadside installations. The objective of the SeeRoad system is
to perform a single-lane plate recognition using a software trigger. It is based on the
image only, detecting the motion within a predefined "hot" detection rectangle.
The system is used to monitor the traffic of vehicles at the side of a road or
highway lane, in order to alert on the detection of wanted vehicles (for example,
stolen cars) or for other purposes. It could also be used to read license plates from a
Video Tape for post analysis.
This system is based on the SeeCar Vehicle License Plate Recognition (LPR)
software, which is used as a DLL and is integrated into the system.
The description in this document applies to SeeRoad version 1.4 and higher. Note
that SeeRoad supercedes the former SeeLaneTrigger application which performed the
some of the same objectives, with improved functionality and performance.

3.Overview
3.1.Product description
SeeRoad is a sophisticated image processing system that tracks the cars’ plates,
reads and identifies their numbers. The identified number is displayed on the system
display, and can be transferred to other Windows applications (via DDE message).
The image file is also saved on disk as a JPG image.
It can be placed at the side of a traffic lane or in any other location that requires
automatic identification. Each unit can control a single lane. The car detection
(triggering) is performed by a software trigger, thus it is optimized for temporary
roadblocks that can be quickly installed.
3.2.System Configurations
SeeRoad has only a single-lane configuration, but can be configured with several
cameras to one of the following options. (Each configuration is predetermined in the
license plug, and preset at the factory).
•
•
•
Single camera per lane (the default option; for standard lanes)
Dual camera per lane (“Stereo”; for wider lanes)
Additional color camera (to take a wide color view)
SeeRoad Technical Manual
page 6
3.3.System Architecture
SeeRoad is a turnkey system, and is based on the following elements:
3.3.1.Hardware Elements
• a PC Pentium running Windows 2000 or XP, with at least 1G RAM
• SRH - SeeRoadHead – a special Camera/Illumination unit (for day & night
operation) which is optimized for this application. It has a more powerful
illumination and lens than the standard SeeRoadHead. Additionally, this unit could
be a standard PAL camera without illumination. See “Using other cameras”
section.
• Frame Grabber(s) - which capture the images from the camera units
• Optional I/O card - multiple I/O discrete lines - which supports the illumination
control. The board is optional, and SeeRoad can run without the I/O control.
3.3.2.Software Elements
• SeeRoad Windows application,
• SeeCar DLL - software package which is used to analyze the images and extract
license plate string.

3.4. Interfacing with SeeRoad
3.4.1.DDE message and Client applications
SeeRoad outputs a DDE message which is compatible to the SeeLane system (see
reference #2.2). It contains the recognition results, date and time, and an image file
path.
•
•
•
•
Therefore, it could be interfaced with the following “Client” applications:
SeeLaneClient (which writes the data to a log file). Its sources are provided with
the SDK in VC++ and VB, and is useful as a sample application which can
simplify the integration.
SeeLaneLog (another viewer, useful for off-line review),
SeeCarTrap (which activates a sound-card “siren” on a stop list),
any other Client Application which is based on these DDE messages.
3.4.2.Windows Event logging
SeeRoad performs events reporting about most critical operations and its results. It might be
useful to check the Event Viewer. For example,if the program fails to start, examine the
application section for more info.
3.5.Technical Document overview
This document is structured as follows:
Section 4 - describes the physical/mechanical installation
Section 5 - describes the hardware installation (with the PC shut down)
Section 6 - describes the software and driver installation (PC powered up)
Section 7 - details the SeeRoad application operation and setting
Section 8 – describes the use of other camera types.
SeeRoad Technical Manual

4.Mechanical Installation
4.1.Overview
This section describes the mechanical/physical installation.
4.1.1.Installation Assumptions
The following lens are assumed:
•
50 mm lens manual-IRIS
This will be referred as "standard lens" installation.
4.2. SeeRoad Head installation
4.2.1.Height of SeeRoadHead
4.2.1.1.Typical Heights
For most installations, install the SeeRoadHead (SRH) on a tripod at a recommended
height of 1.1 meters (or within 1m-1.2m).
This height optimizes the performance and positions the camera to look downwards in
order to minimize the sun effect – since most plates are mounted at a height of 0.20 to
1.25 meters.
SeeRoad Technical Manual
page 9
4.2.2.Distance from Front Plate
This paragraph refers to installation of the camera in the front of the vehicle.
Install the SRH as close as possible to the traffic lane, within 0.5 – 1.5 meters. The
smaller the better! See the illustration above, parameter B. This can be on both sides
of the traffic lane. Do not attempt to recognize from the second lane since the angle of
view will be too steep and the car will pass by at a high rate of angular change.
The camera unit should be installed at a certain range from the “line of the detection”
of the front of the car (parameter A in the following illustration). The range is
determined by the plate size and the lens on the camera, and should not be too far (the
illumination will decrease) or too close (the field of view will be too small). The “line
of detection” is the position when the software trigger detects the plate.
The following diagram shows this setup.
Vehicle
Vehicle
B
SCH
A
Figure 4.2.2: Front Installation distances (See text for explanations)
Typical ranges for parameter A are:
• European (55cm) plates with 50mm lens – 15-17 Meters
• European (55cm) plates with 25mmlens – 8-9Meters
• USA (35cm) plates with 50 mm lens – 12-13 meters
SeeRoad Technical Manual
page 10
4.2.3.Dual Camera per lane
For wide lanes, two cameras may be set to cover the entire lane. The first camera
may be set (for example) on the left side, while the second camera covers the right
side - with some overlap.
SeeRoad operates in parallel and operates the software trigger on each camera
separately. Upon trigger, only the triggering camera performs the recognition.
4.2.4.Rear Capture
SeeRoad can also be installed to capture the rear plates. The installation distance is
the same as the front installation, and is shown in the following diagram.
Figure 4.2.4 Rear Installation
In such case a special option should be set to flag the rear-plate logic mode (see
SeeRoad settings section). The rear-plate logic will trigger when the trigger stops,
which happens when the vehicle exits the trigger zone. This is different than the front
trigger, where the recognition will start when the trigger starts.
SeeRoad Technical Manual
page 11
5.Hardware Installation
This section covers the hardware installation.
Note that all the next steps will be performed with the PC powered off.
5.1.SeeRoadHead
This paragraph assumes that the HTS special integrated camera/illumination unit is
used. For other camera models, please refer to the special-cameras section.
5.1.1.Camera Wiring
A.
Connect the wire PWR: red (+) and black (common) wires from SRH to the
power supply (PS). Do not plug the PS to mains yet! Make sure that the power
supply is located close to the camera (up to 5 meters, recommended 2 meters).
Note that for a car installation, a DC to AC (100-240VAC) converter is
required, recommended at 500-1000 Watt according to the PC requirements.
Note that each camera average power requirements is about 50Watt.
B.
The other connections (green and white control signals) will be connected in
the following steps. Warning: Avoid connecting these signals to the red
power wire, since it will damage the control circuit.
5.1.2.Light Safety Notations
Note on Compliance with International Standards:
The illumination unit (part of the SeeRoadHead) complies with International
Standard IEC 60825-1, for Class 1 LED (light emitting diodes) product containing
Class 1 LED’s. Class 1 LED product poses no hazard to the user or to any other
person present near the illumination unit. The use with the illumination unit is totally
safe and needs no specific precautions.
SeeRoad Technical Manual
page 12
5.2.Frame Grabber(s)
The system is based on one to three frame grabbers, according to the number
of cameras supported by the system.
There are two types of frame grabbers – BASIC or FULL. The “basic” frame grabber
will be used for a single camera, and the “full” may support two cameras in parallel
(but they must be both monochrome).
Install each frame grabber as follows:
A.
Insert the frame grabber (FG) into a PCI slot. Don’t power up the PC yet.
B.
Connect the coaxial cable from SRH to the FG (a BNC plug).
C.
Use the supplied SMB to BNC adapter cable to connect to the camera’s video
cable: connect SMB side to first channel of each frame grabber (near the
LED). In case of a FULL RIO frame grabber, connect the two cameras to
channels 1 & 2.
Note that the SMB connector and wire is delicate - please handle it with care.
D.
Try to minimize the distance from the cameras to the frame grabber (and PC)
as much as possible. Recommended distances to all the SRH is about 45meters (as our supplied cable) up to 30-40meters. In case of the longer
ranges, it is advised to have the power supply close to the SRH unit rather
than supplying its power over the long lines.
E.
Some PC motherboards may have conflicts with the frame grabber. A list of
recommended motherboards is available in the on-line support page.
SeeRoad Technical Manual
page 13
5.3.Optional I/O Card and TBL
SeeRoad can run without an IO card, but in this case the Illumination will be hardwired rather than controlled by the application. Please consult with us on this issue.
We currently supply only one set of I/O cards and TBL terminal blocks.
The set consists of the I/O board (PCI-1751), flat cable of 68 pins, TBL-6822 terminal
block (TBL) with a series of screws and LEDs, and a cover box.
A.
Do not change the factory settings on the PCI board.
B.
Install the I/O card in one of the free PCI bus slots in the computer.
C.
Connect the flat SCSI-68 cable to the I/O card. On the other end connect the
TBL 6822 terminal block (which has a connector for the cable).
D.
Connect the SeeRoadHead (SRH) wires as follows (for the first camera; other
cameras are wired at higher contacts in pairs):
•
•
E.
white wire LSB from SRH to contact no.9 on the TBL, and
green wire MSB from SRH to contact no.10 on the TBL
Note that when the PC is powered up and the SeeRoad application is running
(this will be done after completing the software installation), the default state
of the TBL will be:
• all active inputs and outputs LEDs are off,
• power-on led is on
5.4.Software and Driver installation
Now the software installation steps will be required in order to complete the
installation, as described in the next section.
SeeRoad Technical Manual
page 14
6.Software installation
This section covers the software and drivers installation. It assumes that the hardware
units were already inserted into the computer slots (as covered by the previous
section) and the PC is yet shut down.
Note: The software installation is automated in some Country Releases by an
automatic installation program. The text below assumes that the installation program
is not yet released for your country and a manual installation is required.
6.1.Power up the PC
Power up the PC.
Wait until the Windows operating system boots up. It will notify that a new card has
been detected.
6.2.Frame grabber Driver
The following text assumes the 6-lane RIO frame grabber.
Following the Windows driver request, install the frame grabber driver that is
supplied within the frame grabber package, or on the release CD.
6.2.1.Installing under Windows 2000
•
Make sure you are logged on to Windows 2000 with administrative
privileges.
•
Insert the first Rio installation disk into the floppy disk drive or the Rio
CD-ROM into the CD-ROM drive.
•
Run Setup.exe from the first Rio installation floppy disk or the Rio CDROM.
•
Follow the instructions on the screen.
6.2.2.Testing the installation
After installation on Windows 2000, the Rio Frame Grabber can be used with the
RioWin windows application, to start grabbing.
Alternatively, running the SeeRoad application as described later could also perform
this test.
SeeRoad Technical Manual
page 15
6.2.3.Multiple frame grabbers
If more than one frame grabber is installed (for parallel capturing by a second
camera, or for color image capturing) – you will need to change the frame grabber
number to start from 1.
Use the Start/Settings/Control-Panel RIO Driver settings to define the board ID to a
unique number (to 1 for first board, 2 for second board,…).
SeeRoad Technical Manual
page 16
6.3.I/O card driver - PCI BUS boards
This is optional – in case an IO card is installed for illumination control.
The PCI-1751 I/O card is a plug & play board and is easy to install.
6.3.1.PCI-1751 Driver Installation
Place the I/O card CD in your CD-ROM Device, then its setup application will
automatically activate. Now click the drivers option, then click your
operating system option, then follow the setup instructions.

6.3.3.1.Test with driver test program
A test program is provided with the installed device driver: the device self test. Select
the device self test using the following Windows options:
start -> programs -> Advantech Drivers -> Device Test
This self test allows you to set each output and see its affect on the TBL leds. It
also allows to test the state of the input (high or low for each input). Use this test to
verify the proper installation of the I/O card.
6.3.3.2.If the tests fail
If this fails, uninstall and re-install the drivers and device.
6.4.HASP License-Plug driver
The license plug (HASP) dongle requires an additional installation. Install its driver
that is included in the \driver\Hasp directory: run the hdd32.exe installation
application.
Additionally, insert the dongle to the printer (parallel) port.
Note that a USB plug is also available if required.
SeeRoad needs a special license to execute. Verify that the lable on the plug indicates
“SeeRoad” and the proper number of cameras configured to run with it.
SeeRoad Technical Manual
page 19
6.5.Prepare the SeeRoad directory
6.5.1.SeeRoad Directory
Make a SeeRoad directory in your hard disk. Copy the SeeRoad release directory
files to your disk.
Note: If you have a different frame grabber than the default RIO 6-lane frame
grabber, copy the suitable SeeRoad.exe from the child directory according to the
appropriate frame grabber (such as VFW).
6.5.2.ShortCut and Startup
Create a shortcut icon on the Windows desktop for convenience. You can also add the
SeeRoad to the startup menu.
6.5.3.SeeLane Client
You can also copy the SeeLaneClient application to the same directory. The Client
application intercepts the DDE messages and saves them onto a log file.
You can also make your own application to intercept the messages.
6.6.Power up the SeeRoadHead
A.
Connect the PS to mains (110-240 VAC).
B.
Check that the camera is functioning by running the live video tests using
either the Windows application that is supplied with the frame grabber driver
(RIO Win), or (better) with the SeeRoad application.
SeeRoad Technical Manual
page 20
7.SeeRoad setting
This section describes how to set the SeeRoad application for best results. It
assumes that all software, hardware and drivers are already installed - as covered by
the previous sections.
The following pages contain descriptions of the various settings and operation states
and modes. Most of the screen are for the maximum configuration of 3 cameras.
Upon the first execution the SeeRoad might not run. In this case - examine the
Windows Event application log with the Windows Event viewer. When it runs, a
message box will appear “Please enter settings and verify video Settings”. The
application is shipped with a default setting, which fits most of the installations, but it
requires a review in the first time it is executed. For more information on these
settings, please refer to the information in the following sections.
SeeRoad Technical Manual
page 21
7.1.Main Display
After activating the SeeRoad application, its main display will appear.
The following illustration shows a typical display, which consists of the following
display elements:
• Main image display (in the center) – shows the last capture and recognition
result as title. In the capture history mode it will display the selected event.
• Events history (on the right table) – shows the history of the recognitions. In
Idle mode a certain event can be selected and displayed.
• Trigger status (on the bottom) – the live status of the trigger (state switch from
ON to OFF)
• Operation mode status (on the bottom right corner)
• Uptime (on the bottom right corner)
• Options and option icons (on top side)
• Camera display tabs (on top side of display)
Figure 7.1: Main SeeRoad Display (in capturing on-line state)
SeeRoad Technical Manual
page 22
7.2.Operation States
The application operates in the following states:
1. Capturing state (online) – the system runs, checks for trigger condition,
and recognizes the car plates after each trigger
2.
Offline states
o Idle state – the system is not capturing, and can be used to display old
events (by double-clicking on a line in the history list)
o Live Video state – displays the live video from the camera, and can
optionally change the trigger size and location
o Settings change state – system parameters and configuration can be
changed.
The status display indicates the current state by flashing black/white (“capturing”
online state) or a steady green (offline states).
These states are detailed in the following pages.
7.2.1.Capturing State (on-line)
The previous figure (7.1) shows a sample display for this state. Passing cars are
detected by the Software trigger, and when this occurs the system performs
recognition and outputs the result to the display and to the events history (at right).
The bottom display also shows the current status of the trigger.
The operator may start or stop the capturing using the menu options of the start/stop
icons or (F2 ) button.
In case the trigger is not set correctly (for example, triggering when there is no car,
or not triggering when a car passes), it could be updated (see below – updating the
trigger in live mode). The system also automatically updates the trigger to
accommodate for this case (although it may take a few minutes) and to accommodate
the change of environment light (switch from day to night for example).
SeeRoad Technical Manual
page 23
7.2.2.Idle State (off-line)
This state is when no capturing is performed, and may be used to switch to other
states or to display old events.
To view previous events in the Idle state, simply double-click on the desired event
on the right list. The display will show that event’s image and the recognition results.
The following figure shows an example.
Figure 7.2.2: “Old” Events history display (double click and see)
SeeRoad Technical Manual
page 24
7.2.3.Live Video & Trigger Update
You can view the camera output using the SeeRoad’s built-in live mode. In this
state the main display will show the live video of the selected camera (the tabs on top
of the display select one of the enabled cameras).
The trigger zone (a red rectangle) is displayed. When a car passes the zone and is
detected, the title “Trigger” will appear in the center of the triggering zone. Note that
the color camera is an exception and will not show the trigger zone.
To update the trigger zone, select the top-left corner with the cursor and drag it right
wise and downwards - with the left mouse button kept pressed. When the desired size
is achieved, stop pressing the button. To make this new rectangle the desired
detection zone, select the “Trigger Zone” Update option. The application will then
“learn” the content of the zone and adapt to it. Then new cars will be detected with
the new zone and you should check the operation with a dozen or so cars.
To resume the old (“current”) zone, you may select “Show Current” option. This is
possible only if the “Update” was not pressed before.
Figure 7.2.3: Live video and Trigger update
SeeRoad Technical Manual
page 25
7.2.3.1.Change Video Settings
You can optionally change the following frame grabber and algorithm video setttings:
• brightness and contrast (best values are 80 and x1.3),
• input-gain (usually, don’t change this),
• trigger threshold (10 is default and recommended; lower is more sensitive;
higher is less sensitive).
After the change, press on “Update” in order to update the detection zone trigger.
SeeRoad Technical Manual
page 26
7.2.4.Settings-Change State
SeeRoad is set to a default settings. You will probably need to update these settings.
7.2.4.1.General Settings
The following parameters may be changed:
• Images directory (will save the images as daily subdirectories at that path). It
is advised to use short paths (such as c:\images).
Figure 7.2.4.1: Changing the General settings
•
Identification parameters –
o Repeated IDs set how many same recognitions should be seen in order
to output the result (2 is best for less noisy outputs; 1 is best for fast
traffic).
o Capture on Trigger – the number of images captured at the trigger
(optimum is 3; depends on the traffic speed and the CPU power)
o Rear plate logic – mark this option in case the camera is looking at the
rear plate.
SeeRoad Technical Manual
•
page 27
o Send color image name – in case of a color camera configuration, the
result message will include the color image name rather than the
monochrome recognition camera name.
Password – optionally protect the settings by inserting a password.
7.2.4.2.Camera Setting
The following parameters may be changed for each camera:
• Enabled – is the camera enabled (default) or not. If enabled - the title at the
right will show the type of video signal and its status. The title is updated after
pressing the Apply button, or upon entry.
• Frame grabber (number) – The ID of the frame grabber.
• Illumination LSB pin – the TBL output connection of the first (lsb-white)
wire. The MSB will be the next output pin. These settings are disabled in case
of no IO card installation.

8.Using other cameras
This section describes possible configurations of SeeRoad with other types of
cameras.
8.1.MinTron MTV-13V3HC
8.1.1.Overview
SeeRoad can be shipped with Mintron camera model MTV-13V3HC. This camera
is a high resolution 1/3” black & white CCD camera which can be used in cases of
non-reflective plates or other special cases. The camera is shipped in a special
weatherproof enclosure (which its model and specifications may change from time to
time).
Additional external illumination, either pulsed solid-state or permanent illumination
installed at the site, may be used to cover both day and night operation.
The camera is equipped with lens (usually a DC drive mode). The lens are normally
vari-focal lens up to 50 mm, and can be manually set to the proper zoom.
