Description
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.
Remarks
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.
