Square Detector

the first demo for OpenCV

#inlucde<opencv2\opencv.hpp>
using namespace cv;
int main()
{
    Mat picture=imread("wallpaper")
    imshow("测试程序",picture);
    waitKey(20180717);
}

Script diagnosis requires some permissions to be installed on their folders.Do you want to fix this question?

OpenCV read the picture path(The "Square Detector" program)

• Absolute Path:It's the path starting from the disk,like——D:\OpenCV 3.1\opencv\sources\samples\data\pic1.png

• Relative Path:It's the path starting from the current path,if the current path is "E:\VS2015\ConsoleApplication1\ConsoleApplication1"
• If you want to describe the path(E:\VS2015\ConsoleApplication1\ConsoleApplication1\pic1.png),just input the relative path"pic1.png".In fact,the strict relative path writing should be ".\pic1.png".

• "./"(It means that the current path can be omitted under normal)

  • //The "Square Detector" program
  • //It loads several images sequentially and tries to find squares in
  • //each image

static const char* names[] = { 
        "D:/OpenCV 3.1/opencv/sources/samples/data/pic1.png",
        "D:/OpenCV 3.1/opencv/sources/samples/data/pic2.png",
        "D:/OpenCV 3.1/opencv/sources/samples/data/pic3.png",
