车道线检测算法

在这里插入代码片 ```#include<iostream> #include <opencv2/core/core.hpp> #include <opencv2/highgui/highgui.hpp> #include <opencv2/imgproc/imgproc.hpp> #include <opencv2/video/tracking.hpp> using namespace std; using namespace cv; int main() {Mat img, src;img = imread("C:\\HelloOpenCV\\HelloOpenCV\\3.png", 0);src = Mat(img.size(), CV_8UC1);src.setTo(0);int val = 0;for (int j = img.rows / 2; j < img.rows; j++) {unsigned char* imgptr = img.ptr<uchar>(j);unsigned char* det = src.ptr<uchar>(j);for (int i = 10; i < img.cols - 10; ++i) {if (imgptr[i] != 0) {val = 2 * imgptr[i];val += -imgptr[i - 10];val += -imgptr[i + 10];val += -abs((int)(imgptr[i - 10] - imgptr[i + 10]));val = (val < 0) ? 0 : val;val = (val > 255) ? 255 : val;det[i] = (unsigned char)val;}}}threshold(src, src, 40, 255, 0);//threshold(img, img, 40, 255, 0);//imshow("img", img);imshow("src", src);waitKey(0);destroyAllWindows();system("pause");return 0; }
