本文介绍了使用C ++ opencv在黑白图像中查找对象的中心点的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我有下面的图片。我的目标是找到对象中心点的x,y值。我试过中,您可以在这里找到图像的中心:
///获取质量中心: vector< Point2f> mc(contours.size()); for(int i = 0; i< contours.size(); i ++) {mc [i] = Point2f(mu [i] .m10 / mu [i] .m00,mu [我] .m01 / mu [i] .m00); }你可以找到你的图像中心:
#includeopencv2 \ openncv.hpp using namespace cv; int main() { Mat1b gray = imread(path_to_image,IMREAD_GRAYSCALE); 时刻mu =时刻(灰色,真实); 点中心; center.x = mu.m10 / mu.m00; center.y = mu.m01 / mu.m00; Mat3b res; cvtColor(gray,res,CV_GRAY2BGR); circle(res,center,2,Scalar(0,0,255)); imshow(结果,res); waitKey(); 返回0; }结果图片是:
I have the image below. My aim is to find x,y values of the center point of the object. I tried Image moments but I couldn't find any x,y values. How can I do that?
The center point shoud be the red point or something close to it.
解决方案In the link you posted, you can find the center of the image here:
/// Get the mass centers: vector<Point2f> mc( contours.size() ); for( int i = 0; i < contours.size(); i++ ) { mc[i] = Point2f( mu[i].m10/mu[i].m00 , mu[i].m01/mu[i].m00 ); }You can find the center of your image like this:
#include "opencv2\opencv.hpp" using namespace cv; int main() { Mat1b gray = imread("path_to_image", IMREAD_GRAYSCALE); Moments mu = moments(gray, true); Point center; center.x = mu.m10 / mu.m00; center.y = mu.m01 / mu.m00; Mat3b res; cvtColor(gray, res, CV_GRAY2BGR); circle(res, center, 2, Scalar(0,0,255)); imshow("Result", res); waitKey(); return 0; }The resulting image is:
