OpenCV OpenCV Create a color recognition class-class COLORDETECTOR__OPENCV

Declare its constructor private and provide a static interface to get the Colordetector object

void Setcolordistancethreshold (int) to set thresholds
void Settargetcolor (unsigned char, unsigned char, unsigned char)
void Settargetcolor (CV::VEC3B) for setting colors
BOOL Setinputimage (std::string) for loading pending images
The Cv::mat GetResult () const is used to return the processing result, and the result is represented by a pair of images
