Unable to launch ueye XS in ros indigo, API 4.61

[mklingen]

Simply trying to launch the xs_bayer_rggb.launch file with my ueye XS camera I get this error:

` `` [ INFO] [1431717546.571885057]: Unable to open camera calibration file [/home/mklingen/.ros/camera_info/camera.yaml] [ WARN] [1431717558.304534102]: Internal image scaling is not supported by camera [ WARN] [1431717558.305973604]: Auto frame rate mode is not supported for UEye camera 'camera' (IS_NOT_SUPPORTED) [ WARN] [1431717558.306020556]: Auto exposure mode is not supported for UEye camera 'camera' (IS_NOT_SUPPORTED) [ WARN] [1431717558.627241852]: Failed to set white balance red/blue offsets to 0 / 0 for UEye camera 'camera' [ERROR] [1431717558.627325580]: Failed to initialize UEye camera 'camera'

Try code again using rev e164973de7d30f612ef395301ddc6250737d5313.

Your previously posted error messages seem to suggest that the XS camera being used has a limited feature set. Since I don't have an XS camera on hand, we will need to debug this issue together.

thanks for the rapid response, here are the errors:

    [ WARN] [1431962044.713433898]: Internal image scaling is not supported by camera

This is the exact camera I have:

I can confirm that in ueye_test I have control over auto exposure, auto white balance, etc.

I am perplexed as to where the code is failing. The last error message in your log suggests that the function UEyeCamDriver::connectCam() is failing. Every return statement in that function, except for the final one, is accompanied with an ERROR_STREAM() print-out. Weirdly, I don't any such error printouts in your posted log.

Could you try identifying which "is_*()" function call is failing inside connectCam(), e.g. using extra print statements or a debugger?

[mklingen]

I added additional print statements. Connectcam succeeds, but reading the ROS parameter file fails:

Entering connectCam
ConnectCam succeeded!

simply commenting out the return there (at parsing the ROS param file) so that it returns IS_SUCCESS gets it to work, and it now spits out images. The images appear to be interlaced mono images (I'm guessing raw bayer images)

[mklingen]

I can now get color RGB images using the debayer, however I did have to comment out the check for the access violation on setting the white balance to get it to work.

Please confirm that bf8b57c8eaaa253a435371c4e18d52ecb53e74cc works with your setup.

Works, thanks!
