基于OpenCV进行相机标定是一个常见的计算机视觉任务，它帮助我们了解相机内部参数并校正图像畸变。下面是一个简单的C++代码片段，展示了如何进行基本的相机标定过程： ```cpp #include <opencv2/opencv.hpp> #include "calib3d/calibrationutil.h" using namespace cv; // 定义相机标定参数 cv::Mat cameraMatrix; cv::Mat distCoeffs; // 读取棋盘图片数据 std::vector<cv::Mat> images; for (int i = 0; i < num_images; i++) { Mat image = imread("image_" + std::to_string(i) + ".png", IMREAD_GRAYSCALE); if (!image.data) return -1; images.push_back(image); } // 初始化相机参数 cv::Size imageSize(images[0].size()); cv::FileStorage fs("camera_calibration.xml", FileStorage::WRITE); fs << "camera_matrix" << cameraMatrix << "distortion_coefficients" << distCoeffs; // 执行相机标定 std::vector<std::vector<Point2f>> objectPoints; std::vector<Mat> imagePoints; findChessboardCorners(images, patternSize, imagePoints, objectPoints); cv::calibrateCamera(objectPoints, imagePoints, imageSize, cameraMatrix, distCoeffs, noArray(), noArray()); // 保存结果 fs.release();
