2017-05-16 10:35:02 -0600 | asked a question | VideoCapture captures at low fps Hello I have a camera that captures video (according to the specifications) at a resolution of 640x480 at 120fps. I use the script below to check the speed I can capture frames with OpenCV on Python, but unfortunately I can't capture at the same speed, not even close. By setting I recorded a video with a recorder to see if the camera can actually get that kind of speed and the result, although not close enough to 120, is 50fps. I can see that there is probably a problem with the camera itself, but the difference between the code and the recorder is still at 20 fps. So the question is: Why I can't get higher fps capture with OpenCV on Python, at least as close as the video I recorded? Can I get high (~120) fps capture at all? If yes, which camera does actually work (with OpenCV)? Thank you in advance |
