stm32使用OV2640摄像头二值化代码
使用STM32F+OV2640进行色块识别，希望对你有帮助
先把RGB565转换为灰度图，再进行判断二值化，对白色坐标进行取平均，就可以获得小球坐标，学习STM32F4的DCMI接口和OV2640摄像头模块的使用.。
本实验开机后，初始化摄像头模块（OV2640），如果初始化成功，则提示选择模式：RGB565模式，或者
JPEG模式。KEY0用于选择RGB565模式，KEY1用于选择JPEG模式。
当使用RGB565时，输出图像（固定为：UXGA）将经过缩放处理（完全由OV2640的DSP控制），显示在LCD
上面。我们可以通过KEY_UP按键选择：1:1显示，即不缩放，图片不变形，但是显示区域小（液晶分辨率
大小），或者缩放显示，即将1600*1200的图像压缩到液晶分辨率尺寸显示，图片变形，但是显示了整个
图片内容。通过KE0Y按键，可以设置对比度；KEY1按键，可以设置饱和度；KEY2按键，可以设置特效。
当使用JPEG模式时，图像可以设置任意尺寸（QQVGA~UXGA），采集到的JPEG数据将先存放到STM32F4的内
存里面，每当采集到一帧数据
