To follow up on the original question, we've done some internal testing on the HTC One and discovered that the device can lose the ability to auto focus. This occurs below the Vuforia layer - i.e. it's an issue with device's own camera control . But the autofocus can typically be restored by pausing and resuming the app. Jul 15, 2019 · Using OpenCV directly For reasons I understand and still get annoyed with, opencv defaults to 640x480 on most webcams. So the code: vs = cv2.VideoCapture(0) , will stream 640x480 frames regardless of your webcam’s capabilities. - Learn OpenCV data types, array types, and array operations - Capture and store still and video images with HighGUI - Transform images to stretch, shrink, warp, remap, and repair - Explore pattern...
