本程序主要是通过模板匹配的方法来对LED显示模块上的每个灯进行亮度检测。主要是根据模板图像和已知的图像的欧氏距离来进行检测。-This procedure is mainly through template matching method to the LED display module detects the brightness of each lamp. Mainly based on the template image and the known image of the Eucl

用于检测环境光线，光线强，则灯亮度小，以保证整体光强稳定在一个范围-Used to detect ambient light, strong light, the brightness is small, in order to ensure the overall light intensity and stable in a range

图像读取及灰度变换、图像旋转、边缘检测、图像反转灯非常实用的图片处理技巧-Image reading and gray-scale transformation, image rotation, edge detection, image inversion lights very useful image processing techniques
