2017-07-06 03:03:31 -0600 | commented question | Gaining high frame rate from ELP camera (python) I decided to upgrade to OpenCV 3 and this has made all the difference. Frame rate immediately rose greatly. Thanks for all your help, Berak. |
2017-07-05 05:07:07 -0600 | commented question | Gaining high frame rate from ELP camera (python) Ah ok. So this is causing the bottleneck? Is there any method to use to improve the frame rate? |
2017-07-05 04:48:20 -0600 | commented question | Gaining high frame rate from ELP camera (python) In the demo I'm doing absolutely nothing with them. I had assumed that because (most of the time) when a frame is requested None is returned that the requests are coming in far faster than the camera can output them and therefore the queue never has more than one frame on it. |

2017-07-05 04:26:59 -0600 | asked a question | Gaining high frame rate from ELP camera (python) I'm using an ELP USB camera that is supposedly rated at 100fps at 640x480 quality but I don't seem to be getting anywhere near that frame rate. I was wondering if anyone has used an ELP camera with openCV and managed to achieve a frame rate close to 100 fps? Or if anyone has any advice to help increase the frame rate? I am using Ubuntu 14.04 with openCV version 2.4.8. I have already tested that the output is MJPEG at 640x420 and I am running cv2.VideoCapture in one thread and placing the frame on a queue. From the main thread I repeatedly ask for frames but only return when the results is not None. This gives a frame rate hovering around 30fps. One I have the image I am performing contour detection but essentially I would like to get the frame rate up as high as possible. Below is the code I'm using just to test the frame rate. Thanks in advance |
