[0038] In this embodiment, a color camera is used, therefore, the captured image should be processed in grayscale in the monitoring computer. Because for a color image, the pixel value of each pixel contains three components of red R, green G, and blue B, so it is necessary to convert the color image into a grayscale image first. The pixel value of the grayscale image contains only one component, which is convenient for subsequent calculations. ...
