Monitor the signal to noise ratio of 200W monocular digital wide dynamic USB camera module

Signal to noise ratio: in principle, the calculation of signal to noise ratio should be carried out on the premise of ensuring the frame rate, because the pixels used in the error calculation in PSNR formula must come from the decoded and original images of the same frame, that is, a standard video source image corresponds to a compressed decoded image. If this premise is not satisfied, the SNR will be very low
