Problem uvc-radiometry.py #5

Closed ignacio1988 closed 6 years ago

Hi, I receive the following error and I do not understand why it happens. I updated the firmware to 1.0.0 https://github.com/groupgets/purethermal1-firmware/releases/tag/1.0.0 and sometimes I can acquire images but I can not determine why. Any recommendation?

device opened! Version gpp: 0.0.0 dsp: 0.0.0 FLIR part #: FLIR serial #: '\x00\x00\x00\x00\x00\x00\x00\x00' format: YUY2 frame 640x480 @ 30fps frame 160x120 @ 30fps frame 176x144 @ 30fps frame 320x240 @ 30fps frame 352x288 @ 30fps device does not support Y16

The frame sizes don't match what the PT1 firmware would be reporting, and all the version information is bogus. I would guess that a different camera on the system is being opened, do you have more than one UVC device connected?

Hi, i connected a web camera with opencv at the same time wich purethermal for adquisition in parallel in the same code python.

OK... well have you pulled on that thread to determine if the simultaneous OpenCV is what is causing the conflicts?

Hi, I discovered my problem. UVC did not find the purethermal because the USB VID/PID is was not the right one, I replaced the following line of code res = libuvc.uvc_find_device(ctx, byref(dev), 0, 0, 0) for this res = libuvc.uvc_find_device(ctx, byref(dev), 0x1e4e, 0x0100, 0). Thanks very much. REF: https://groups.google.com/forum/#!topic/flir-lepton/OLyUetrvMow

Good call, I have updated the examples with the change.
