What units of measure is the focal length?

I would like to input the focal length of my device but I am not sure what value to type in.

Referenced here:

lightweight-human-pose-estimation-3d-demo.pytorch/demo.py

Line 95 in 8794edc

if fx < 0: # Focal length is unknown

and here:

lightweight-human-pose-estimation-3d-demo.pytorch/modules/parse_poses.py

Line 133 in 8794edc

mean_2d = np.array([mean_2d[0, 0], mean_2d[1, 0], fx * input_scale / stride])

If I have a focal length of 1474px, where should I input that value in "parse_poses"?

Hi! They are in pixels. You can find the details here, or check #47.
