你好,我已经开发了一个绘制输入图像轮廓的软件,现在我不想将它带到下一层,并围绕感兴趣的对象绘制边界框,即一个人。我查看了boundingRect()函数,但我很难理解它。也许有不同的函数算法绘制边界框.....?绘图在C++环境中使用OpenCV的边界框
这里是我的程序的代码:
#include "iostream"
#include<opencv\cv.h>
#include<opencv\highgui.h>
#include<opencv\ml.h>
#include<opencv\cxcore.h>
#include <iostream>
#include <string>
#include <opencv2/core/core.hpp> // Basic OpenCV structures (cv::Mat)
#include <opencv2/highgui/highgui.hpp> // Video write
using namespace cv;
using namespace std;
Mat image; Mat image_gray; Mat image_gray2; Mat threshold_output;
int thresh=100, max_thresh=255;
int main(int argc, char** argv) {
//Load Image
image =imread("C:/Users/Tomazi/Pictures/Opencv/tomazi.bmp");
//Convert Image to gray & blur it
cvtColor(image,
image_gray,
CV_BGR2GRAY);
blur(image_gray,
image_gray2,
Size(3,3));
//Threshold Gray&Blur Image
threshold(image_gray2,
threshold_output,
thresh,
max_thresh,
THRESH_BINARY);
//2D Container
vector<vector<Point>> contours;
//Fnd Countours Points, (Imput Image, Storage, Mode1, Mode2, Offset??)
findContours(threshold_output,
contours, // a vector of contours
CV_RETR_EXTERNAL,// retrieve the external contours
CV_CHAIN_APPROX_NONE,
Point(0, 0)); // all pixels of each contours
// Draw black contours on a white image
Mat result(threshold_output.size(),CV_8U,Scalar(255));
drawContours(result,contours,
-1, // draw all contours
Scalar(0), // in black
2); // with a thickness of 2
//Create Window
char* DisplayWindow = "Source";
namedWindow(DisplayWindow, CV_WINDOW_AUTOSIZE);
imshow(DisplayWindow, result);
waitKey(5000);
return 1;
}
任何人都可以提出一个解决方案...?也许直接给我一些来源,教程等阅读OpenCV文档,并看看boundingRect()函数,我仍然不明白。请帮助:)
是你的问题如何获得边界框的参数或如何使用'rectangle'函数实际绘制它? – sietschie
both:/如果你可以指导我一些简单的源代码或教程,或者如果你能在这里向我解释它,甚至更好。谢谢 – Tomazi
