Workspace \DALSA\Sapera\Demos\Classes\vc\SapDemos.dsw

Description

Remarks

This program demonstrates the basic acquisition functions included in the Sapera library. The program allows you to acquire images, either in continuous or in one-shot mode, while adjusting the acquisition parameters. The program code may be extracted for use within your own application.

This demo is built using Visual C++ 6.0 using the MFC library. It is based on Sapera

C++ classes. See the Sapera User’s and Reference manuals for more information.

Using the Grab Demo

Server Selection

Run the grab demo from the start menu Start • Programs • Sapera LT • Demos • Grab Demo.

The demo program first displays the acquisition configuration menu. The first drop menu displayed permits selecting from any installed Sapera acquisition servers (installed DALSA acquisition hardware using Sapera drivers). The second drop menu permits selecting from the available input devices present on the selected server.

CCF File Selection

The acquisition configuration menu is also used to select the required camera configuration file for the connected camera. Sapera camera files contain timing parameters and video conditioning parameters. The default folder for camera configuration files is also used by the CamExpert utility to save user generated or modified camera files.

Use the Sapera CamExpert utility program to generate the camera configuration file based on timing and control parameters entered. The CamExpert live acquisition window allows immediate verification of those parameters. CamExpert reads both Sapera *.cca and *.cvi for backward compatibility with the original Sapera camera files.

Grab Demo Main Window

Refer to the Sapera LT User's Manual (OC-SAPM-USER), in section "Demos and Examples – Acquiring with Grab Demo", for more information on the Grab Demo.
