OpenCV实现直线检测并消除

本文实例为大家分享了OpenCV实现直线检测并消除的具体代码，供大家参考，具体内容如下

很简单，代码如下

				?

									#include<iostream>

									#include<opencv.hpp>

									using namespace cv;

									using namespace std;

									int main()

									{

									 Mat img, dst, img_gary, img_bin, temp, r_line, c_line, kernel;

									 char INPUT[] = "input";

									 char OUTPUT[] = "output";

									 char GRAY_IMG[] = "gary image";

									 char BIN_IMG[] = "binary image";

									 char DST_IMG[] = "final image";

									 img = imread("D:\\OpenCV\\images\\demo_test_2.jpg");

									 if (img.empty())

									 {

									  cout << "image loading failed..." << endl;

									  return -1;

									 }

									 namedWindow(INPUT, WINDOW_AUTOSIZE);

									 imshow(INPUT, img);

									 cvtColor(img, img_gary, COLOR_BGR2GRAY);

									 imshow(GRAY_IMG, img_gary);

									 adaptiveThreshold(~img_gary, img_bin, 255, ADAPTIVE_THRESH_MEAN_C, THRESH_BINARY, 15, -2);

									 imshow(BIN_IMG, img_bin);

									 //水平结构元素

									 r_line = getStructuringElement(MORPH_RECT, Size(img.cols / 16, 1), Point(-1, -1));

									 //垂直结构元素

									 c_line = getStructuringElement(MORPH_RECT, Size(1, img.rows / 16), Point(-1, -1));

									 kernel = getStructuringElement(MORPH_RECT, Size(4, 4), Point(-1, -1));

									 erode(img_bin, temp, kernel);

									 dilate(temp, dst, kernel);

									 //erode(img_bin, temp, r_line);

									 //dilate(temp, dst, r_line);

									 //morphologyEx(img_bin, dst, MORPH_OPEN, c_line);

									 bitwise_not(dst, dst);

									 //blur(dst, dst, Size(3, 3), Point(-1, -1));

									 imshow(DST_IMG, dst);

									 waitKey(0);

									 return 0;

									}
