OpenCV 颜色空间转换参数CV_BGR2GRAY改变

OpenCV的颜色空间转换函数:
 
C++: void cvtColor(InputArray src, OutputArray dst, int code, int dstCn=0 )
 
参数dstCn原来一直沿用CV_BGR2GRAY, CV_RGB2GRAY, CV_GRAY2BGR, CV_GRAY2RGB等格式,但最新几个版本的OpenCV已改为COLOR_BGR2GRAY类似形式,今天才看源代码imgproc.hpp才发现,但官方文档还没修改,如下图,如果程序中使用较新的版本OpenCV,采用CV_BGR2GRAY可能会一直出错。
 
 
 
新的OpenCV中imgproc.hpp的定义如下:
