I have a project which is the following:
On a jeston Nano, I have a CSI camera. I want to take one picture (fram) every 5s from this cam , and then evaluate this picture in a tensorflow model.
The tensorflow part is working without problem if I use pictures from the hard drive.
The problem is to get one picture every 5 seconds.
I just create this simple piece of code:
cam=nano.Camera(flip=0, width=640, height=480, fps=30) while True: image = cam.read() cv2.imshow("image",image) cv2.waitKey(5000) if cv2.waitKey(1) & 0xFF == ord(' '): break cap.release() cv2.destroyAllWindows()
nano.Camera is just coming from a library:
The problem is that, the delay between displaing 2 pictures is really longer than 5s (more than a minute), it seems that the system is laging.
And when I’m sending the picture to the model, it seems that the evaluation is done correctly. Only the display in cv2.imshow seems to have a problem.
For information, the live from the camera is working fine.
Any idea on this issue?
