opencv生成棋盘格图像

使用双目摄像头进行立体视觉算法时，摄像头标定是必不可少的。通常采用黑白棋盘格的方法，本文采用opencv库实现生成一张黑白棋盘格，棋盘格的格子数可以设定，图片分辨率也可设定，图片格式可以自己修改。代码如下：

#include<iostream>
#include<opencv2\core\core.hpp>
#include<opencv2\highgui\highgui.hpp>
using namespace std;
const int perBoardPixel = 1000;
const cv::Size boardSize(9,7);
const cv::Size resolution(9000,7000);
int main()
{
    
    
	int basisHeight = (resolution.height - perBoardPixel*boardSize.height) / 2;
	int basisWidth = (resolution.width - perBoardPixel*boardSize.width) / 2;
	if( basisHeight < 0  ||  basisWidth < 0)
	{
    
    
		cout<<"Resolution doesn't match!"<<endl;
	}
	cv::Mat image(resolution,CV_8UC1,cv::Scalar::all(255));
	int flag = 0;
	for(int j = 0;j < boardSize.height;j++)
	{
    
    
		for(int i = 0;i < boardSize.width;i++)
		{
    
    
			flag = (i+j) % 2;
			if(flag == 0)
			{
    
    
				for(int n = j * perBoardPixel;n < (j+1) * perBoardPixel;n++)
					for(int m = i * perBoardPixel;m < (i+1) * perBoardPixel;m++)
						image.at<uchar>(n + basisHeight,m + basisWidth) = 0;
			}
		}
	}
	//cv::imshow("haha",image);
	cv::imwrite("chessBoard1.bmp",image);
	//cv::waitKey(0);
	return 0;
}
