Why am I unable to preview the video from my DALSA
Why am I unable to preview the video from my DALSA Genie ethernet camera using MATLAB 7.4 (R2007a)? I am trying to create a videoinput object for my DALSA Genie camera. When I execute the IMAQHWINFO command as follows: imaqhwinfo('winvideo') I recieve the following output: Adaptor Name: winvideo Adaptor DLL: \\ENG3\matlab-r2007a\toolbox\imaq\imaqadaptors\win32\mwwinvideoimaq.dll IMAQHWINFO: AdaptorDllName: [1x71 char] AdaptorDllVersion: '2.1 (R2007a)' AdaptorName: 'winvideo' DeviceIDs: {[1]} DeviceInfo: [1x1 struct] Thereafter, I open the configuration pane for the camera using the AMCap application. Once the configuration pane has been closed, I use the the following commands in MATLAB to create a VIDEOINPUT object: obj = videoinput('winvideo'); preview(obj) However, all I receive is a black preview window with the following error message in the top left corner of the preview window: "No Sapera Acquisition Device Detected! (Currently Simulating Grab)" I have been able to preview the camera output using the Image Acquisition Toolbox 1.7 (R14SP1), however, I get the above error message using the Image Acquisition Toolbox 2.1 (R2007a).
