Control camera bitrate, resolution and framerate

1692371445

I have a RaspTank Pro and Raspberry pi. I have a Raspberry pi high resolution camera and I replaced the original camera of car with my new high resolution camera. But I see after that, the Pi cannot process the video very well. The servo motor and video start lagging.
I undrstand that the Pi may not process the high resolution, bitrate or framerate. How can I change camera resolution, bit rate from OpenCV?

You can try to modify the server/camera_opencv.py file, add below line 418
code:

1. 
   
2.          camera.set(6,cv2.VideoWriter.fourcc('M','J','P','G'))
   
3.          camera.set(3,640) #FRAME WIDTH
   
4.          camera.set(4,480) # FRAME HEIGHT
   
5.          #camera.set(cv2.CAP_PROP_FPS, 60) # frame

Copy the Code

You can also debug the parameters and fill in the parameters suitable for your camera.
