opencv提取图像中红色范围，结果一直出错

int main(int argc,char **argv)
{
IplImage* image = cvLoadImage("C:\\Users\\Public\\Pictures\\Sample Pictures\\***.jpg");
cvNamedWindow("output",CV_WINDOW_AUTOSIZE);
IplImage* imageHSV =cvCreateImage(cvGetSize(image),image->depth,3);

IplImage* image_11 =cvCreateImage(cvGetSize(image),image->depth,3);
cvCvtColor( image, image_11, CV_RGB2BGR );//BRG 转换到 HSV
cvCvtColor( image_11, imageHSV, CV_BGR2HSV );
IplImage* h_space =cvCreateImage(cvGetSize(image),IPL_DEPTH_8U,1);
IplImage* s_space =cvCreateImage(cvGetSize(image),IPL_DEPTH_8U,1);
IplImage* v_space =cvCreateImage(cvGetSize(image),IPL_DEPTH_8U,1);
cvSplit(imageHSV,h_space,s_space,v_space,NULL);//提取HSV各通道

IplImage* h_s1 =cvCreateImage(cvGetSize(image),IPL_DEPTH_8U,1);//H通道域值化

IplImage* h_s2 =cvCreateImage(cvGetSize(image),IPL_DEPTH_8U,1);
IplImage* h_s3 =cvCreateImage(cvGetSize(image),IPL_DEPTH_8U,1);
IplImage* h_s4 =cvCreateImage(cvGetSize(image),IPL_DEPTH_8U,1);
IplImage* h_s5 =cvCreateImage(cvGetSize(image),IPL_DEPTH_8U,1);
cvThreshold(h_space,h_s1,180,255,CV_THRESH_BINARY_INV);
cvThreshold(h_space,h_s2,160,255,CV_THRESH_BINARY);
cvAnd(h_s1,h_s2,h_s3);
cvAnd(h_s3,h_space,h_s5);

IplImage* hsv =cvCreateImage(cvGetSize(image),image->depth,3);
IplImage* image_1 =cvCreateImage(cvGetSize(image),image->depth,3);
cvMerge(h_s5,h_s5,h_s5,NULL,hsv);
cvCvtColor( hsv,image_1, CV_HSV2BGR );
cvShowImage("output",image_1);

cvWaitKey(0);

cvReleaseImage(&image_1);
cvDestroyWindow("output");
}

Answer 1

用你的程序跑了下,你这个应该是提取蓝色区域的代码,
提取红色区域我记得是H空间315°~360°和0°~23°
具体代码你自己 按照这个参数再调试下吧
