我对 iOS 的 Opencv 库有疑问。在模拟器上使用cvHoughCircles
结果与 iPhone 不同。这是代码
CvSeq *circles = cvHoughCircles( gray, //输入图像
storage, //Memory Storage CV_HOUGH_GRADIENT, //Detection method 2, //Inverse ratio gray->width/8, //Minimum distance between the centers of the detected circles 100, //Higher threshold for canny edge detector 20, //Threshold at the center detection stage gray->height/6, //min radius gray->height/2 //max radius );
circles->total
= 在模拟器上为 0,但在 iPhone 上为 1。这是图像
任何帮助将不胜感激。
