#椭圆拟合

首先贴一个最简单的程序：访问：https://blog.youkuaiyun.com/guduruyu/article/details/70069426

//创建一个用于绘制图像的空白图    
cv::Mat image = cv::Mat::ones(480, 640, CV_8UC3);  
//设置蓝色背景  
image.setTo(cv::Scalar(100, 0, 0));  
  
//输入拟合点    
std::vector<cv::Point> points;  
  
points.push_back(cv::Point(200, 240));  
points.push_back(cv::Point(300, 400));  
points.push_back(cv::Point(400, 360));  
points.push_back(cv::Point(500, 300));  
points.push_back(cv::Point(500, 200));  
points.push_back(cv::Point(300, 150));  
  
//将拟合点绘制到空白图上    
for (int i = 0; i < points.size(); i++)  
{  
    cv::circle(image, points[i], 5, cv::Scalar(0, 0, 255), 2, 8, 0);  
}  
  
//获取拟合椭圆的外包围矩形  
cv::RotatedRect rotate_rect = cv::fitEllipse(points);  
//绘制拟合椭圆  
cv::ellipse(image, rotate_rect, cv::Scalar(0, 255, 255), 2, 8);  
  
cv::imshow("image", image);  
cv::waitKey(0);
