How to get PointGrey camera acquiring image data in Python on Raspberry Pi?

Hi all,

I have 2 Point Grey cameras with code FL3-U3-88S2C-C on their labels. I've had these cameras for some time and have never been able to get them working. I was hoping to get some guidance as I have had no luck with the online support.

Basically, I would like to use these cameras as part of an OpenCV based Python program running on Raspbian or Ubuntu on a single board computer. Right now I'm using a Raspberry Pi 4.

Currently, I can see that my camera is recognised when running the lsusb command in terminal but I get the following error when using the OpenCV VideoCapture(1) function in Python.

[ WARN:0] global /home/pi/opencv/modules/videoio/src/cap_v4l.cpp (802) open VIDEOIO ERROR: V4L: can't open camera by index 1
libdc1394 warning: usb: Failed to open device for config ROM
libdc1394 warning: Failed to get config ROM from usb device

Is there anything you could suggest to help me start acquiring image data?

Thanks!
