"Perform Calibration" quits, & no dropdown access to webcam in preferences menu

[morrisvanegas]

Built on gt5 using SLStudio.pro configuration. I can run SLStudio from inside my newly created build folder, but when I click "perform calibration" SLStudio quits with a "The program has unexpectedly finished." Is this because I have no calibration.xml file?

I can use cheese to preview my webcam (so I know I can see it), but the dropdown menu in Preference inside SLStudio only show "SLStudio Virtual Camera" as an option. Doesnt recognize my USB camera.

Despite two issues above, I tried running without calibration and with "SLStudio Virtual Camera" (Preferences: single point cloud acquisition, 2x3 pattern phase shift, Screen 0 projector, software trigger) and my point clouds are empty, presumably because I am not using my usb webcam.

What matlab shows when I open .pcd output file:

Any tips on calibration and webcam usage would be greatly appreciated! (Also pardon simplicity in questions; first endeavor into c++)

Hi Morris. Your camera is not supported. You would have to extend the camera wrappers for your camera. Presumably you could use OpenCV's camera capture interface. Regards.
