摄像头所采集到的图像及图像处理完成后的显示都需要用到颜色模型，常见的颜色模型包括RGB、HSV、HSL、Lab等，这里我所用到的颜色模型有RGB、HSV。RGB颜色模型分别对应Red（红色）、Green（绿色）、Blue（蓝色）这三种颜色，HSV颜色模型分别对应Hue（色相）、Saturation（饱和度）、Value（明度）这三种参数。将摄像头所采集到的RGB数据通过Python程序转变为HSV数据(The color model is needed to display the image collected by the camera and the display after image processing. The common color models include RGB, HSV, HSL, Lab and so on. The color models used here are RGB, HSV. The corresponding Red RGB color model respectively (red), Green (green), Blue (blue) of the three colors, Hue corresponds to the HSV color model respectively (hue) and Saturation (saturation), Value (Ming Du) of the three parameters. The RGB data collected by the camera is transformed into HSV data through Python program)
