Liquid separation process monitoring and end point identification method and system, storage medium and terminal

The invention provides a liquid separation process monitoring and end point identification method and system, a storage medium and a terminal. The method comprises the following steps: acquiring a liquid separation process video based on an RGB color space; performing edge detection on each liquid separation process image of the liquid separation process video; based on the liquid separation process image after edge detection, extracting a mask image of the liquid separation container; zooming each liquid separation process image of the liquid separation process video into an RGB image with a preset size; matching the RGB image with the mask image to obtain a region of interest of the RGB image; and calculating the image entropy of each region of interest, constructing a time sequence of the image entropy, and selecting the moment corresponding to the maximum value of the image entropy as a liquid separation end point. According to the liquid separation process monitoring and end point recognition method and
