常规方法: 1 void SobelAmplitude(Mat &sobelx, Mat &sobely, Mat &SobelXY) { 2 SobelXY = Mat::zeros(sobelx.size(), CV_32FC1); 3 for (int i = 0; i < SobelXY.r 阅读全文
摘要:
在ORB算法论文中,并没有对尺度空间如何构建进行描述,但是Opencv内部构建了尺度空间,尺度空间层为8。 当然这都是小问题,不知道你们有没有发现一个问题:若A图像尺度空间第一层上有一点a,与B图像尺度空间第三层上的一点b为同一匹配点,这时该如何匹配? 或者说,该如何画出来?这两层所在尺度不同,进行 阅读全文
