As issue describes, the leapuvc python scripts return identity camera paremeters,

In order to get the calibration data on Win it is necessary to use DSHOW backend. However, it looks like using DSHOW backend currently breaks other things so after you get the calibration data create new MSMF capture in regular way. Following should work.

import cv2
import leapuvc

capResolution = (640, 480)
cam = cv2.VideoCapture(0 + cv2.CAP_DSHOW)
cam.set(cv2.CAP_PROP_FRAME_WIDTH, capResolution[0])
cam.set(cv2.CAP_PROP_FRAME_HEIGHT, capResolution[1])
calibration = leapuvc.retrieveLeapCalibration(cam, capResolution)
cam.release()

print(calibration)
