WebStandard Hough Line Transform. First, you apply the Transform: vector lines; HoughLines(dst, lines, 1, CV_PI/180, 100, 0, 0 ); with the following arguments: dst : Output of the edge detector. It should be a grayscale image (although in fact it is a binary one) lines : A vector that will store the parameters ( r, θ) of the detected lines. Web(1)HoughLines() 作用:使用标准霍夫变换在二进制图像中查找线。 image 8位单通道二进制源图像。该图像可以通过该功能进行修改。 lines 线的输出向量。每行由2或3个元素向量表示(ρ ,θ ) 要么 (ρ ,θ ,票数) 。
