用于硬币检测的OpenCV C++程序

以下是对使用工具OpenCV在C++中进行硬币检测的C++代码的说明。

要知道的事情：

1. 该代码仅在Linux环境中编译。
2. 要在Windows中运行，请使用文件：“ coin.o”并在cmd中运行它。但是，如果它没有运行(系统体系结构中的问题)，则可以通过对代码进行适当且明显的更改在Windows中对其进行编译，例如：代替。
3. 编译命令：g ++ -w coin.cpp -o coin.exe`pkg-config –libs opencv`
4. 运行命令：./ coin
5. 包含硬币的图像必须与代码位于同一目录中。
   在运行代码之前，请确保已在//系统上安装了OpenCV。

代码片段说明：

#include "opencv2/highgui/highgui.hpp"
// highgui - an interface to video and image capturing.

#include "opencv2/imgproc/imgproc.hpp"
// imgproc - An image processing module that for linear and non-linear
 image filtering, geometrical image transformations, color space conversion and so on.
#include 
#include 
// The header files for performing input and output.
 
using namespace cv;
// Namespace where all the C++ OpenCV functionality resides.

using namespace std;
// For input output operations.
 
int main()
{
    Mat image;
    // Mat object is a basic image container. image is an object of Mat.

    image=imread("coin-detection.jpg",CV_LOAD_IMAGE_GRAYSCALE);
    // Take any image but make sure its in the same folder.
    // first argument denotes the image to be loaded. 
    // second argument specifies the image format as follows: 
    // CV_LOAD_IMAGE_UNCHANGED (<0) loads the image as it is.      
    // CV_LOAD_IMAGE_GRAYSCALE ( 0) loads the image in Gray scale.      
    // CV_LOAD_IMAGE_COLOR (>0) loads the image in the BGR format. 
    // If the second argument is not there, it is implied CV_LOAD_IMAGE_COLOR.

    vector coin;
    // A vector data type to store the details of coins.

    HoughCircles(image,coin,CV_HOUGH_GRADIENT,2,20,450,60,0,0 );
    // Argument 1: Input image mode
    // Argument 2: A vector that stores 3 values: x,y and r for each circle.
    // Argument 3: CV_HOUGH_GRADIENT: Detection method.
    // Argument 4: The inverse ratio of resolution.
    // Argument 5: Minimum distance between centers.
    // Argument 6: Upper threshold for Canny edge detector.
    // Argument 7: Threshold for center detection.
    // Argument 8: Minimum radius to be detected. Put zero as default
    // Argument 9: Maximum radius to be detected. Put zero as default

    int l=coin.size();
    // Get the number of coins.

    cout<<"\n The number of coins is: "<
