c++ occupancygrid保存为图片

要将C++中的occupancy grid保存为图片，您可以使用OpenCV库。以下是使用OpenCV库将occupancy grid保存为图片的示例代码：

#include <opencv2/opencv.hpp>

// assume occupancy grid is stored in a cv::Mat object called "grid"
// convert grid values to 0-255 grayscale values
cv::Mat grid_img = (grid * 255).clone();
grid_img.convertTo(grid_img, CV_8UC1);

// create image from grid and save it
cv::imwrite("occupancy_grid.png", grid_img);

这将把occupancy grid转换成灰度图像，并将其保存为名为"occupancy_grid.png"的文件。您可以根据需要更改文件名和路径。
