OpenCV：使用VIZ模块进行三维显示

#include 
#include 

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 cloud;
	std::vector 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(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;
}
