我想查看使用 openCv 和 c++ 的图像中是否存在模板。然而,由于拍摄图像的距离不同以及图像的位置不同,匹配不会正确发生。
这是我的代码:
IplImage* image = cvLoadImage("C:/images/Photo0734.jpg", 1);
IplImage* templat = cvLoadImage("C:/images/templatecoin.jpg", 1);
int percent =25;// declare a destination IplImage object with correct size,
depth and channels
IplImage* image3 = cvCreateImage( cvSize((int)((image->width*percent)/100) ,
(int)((image->height*percent)/100) ),image->depth, image->nChannels );
//use cvResize to resize source to a destination image
cvResize(image, image3);
IplImage* image2 = cvCreateImage(cvSize(image3->width, image3->height),
IPL_DEPTH_8U, 1);
IplImage* templat2 = cvCreateImage(cvSize(templat->width,
templat->height), IPL_DEPTH_8U, 1);
cvCvtColor(image3, image2, CV_BGR2GRAY);
cvCvtColor(templat, templat2, CV_BGR2GRAY);
int w = image3->width - templat->width + 1;
int h = image3->height - templat->height + 1;
result = cvCreateImage(cvSize(w, h), IPL_DEPTH_32F, 1);
cvMatchTemplate(image2, templat2, result, CV_TM_CCORR_NORMED);
double min_val, max_val;
CvPoint min_loc, max_loc;
cvMinMaxLoc(result, &min_val, &max_val, &min_loc, &max_loc);
cvRectangle(image3, max_loc, cvPoint(max_loc.x+templat->width,
max_loc.y+templat->height), cvScalar(0,1,1), 1);
cvShowImage("src", image3);
//cvShowImage("result image", result);
cvWaitKey(0);
请注意,我无法使用“垫子”。是否可以使用 IplImage* 并使代码对缩放和旋转保持不变?帮我。
