OpenCV：使用VIZ模块进行三维显示_opencv wcoordinatesystem

#include <opencv2/opencv.hpp>
#include <opencv2/viz.hpp>
 
using namespace std;
using namespace cv;
 
int main(int argc, char const *argv[]) {
	cv::Mat img_in(200, 750, CV_8UC1, cv::Scalar(0));
	std::vector<cv::Vec3f> cloud;
	std::vector<cv::Vec3b> color;
 
	cv::putText(img_in, "Hello World !", cv::Point(75, 150), 0, 3, cv::Scalar(255), 2);
 
	for (int x = -200; x < 0; x++) {
		for (int y = 0; y < 750; y++) {
			cloud.push_back(cv::Vec3f(x, y, img_in.at<uchar>(x + 200, y)));
			color.push_back(cv::Vec3b(255, 0, 0));
		}
	}
 
	viz::WCoordinateSystem world_coor(1.0);
	viz::WPlane plane(cv::Size(200, 200));
	viz::WCloud cloud_widget(cloud, color);
 
	//初始化
	cv::viz::Viz3d window("window");
 
	window.showWidget("World",world_coor);
	window.showWidget("plane", plane);
 
	while (1) {
		window.showWidget("pnt_cloud", cloud_widget);
		window.spinOnce(10, false);
	}
 
	return 0;
}
