以下是使用OpenCV进行相机标定的C语言代码示例： ``` #include <opencv2/opencv.hpp> #include <iostream> using namespace std; using namespace cv; int main() { // 读取标定图像 vector<vector<Point2f>> imagePoints; vector<vector<Point3f>> objectPoints; Size imageSize; int numImages = 10; float squareSize = 1.0; Mat cameraMatrix, distCoeffs; vector<Mat> rvecs, tvecs; for (int i = 0; i < numImages; i++) { Mat image = imread(format("calibration%d.png", i), IMREAD_GRAYSCALE); if (image.empty()) { cerr << "Failed to read image " << i << endl; return -1; } imageSize = image.size(); vector<Point2f> corners; bool found = findChessboardCorners(image, Size(9, 6), corners); if (found) { imagePoints.push_back(corners); vector<Point3f> objectCorners; for (int j = 0; j < 54; j++) { objectCorners.push_back(Point3f(j / 9 * squareSize, j % 9 * squareSize, 0)); } objectPoints.push_back(objectCorners); } else { cerr << "Failed to find chessboard corners in image " << i << endl; } } // 标定相机 double rms = calibrateCamera(objectPoints, imagePoints, imageSize, cameraMatrix, distCoeffs, rvecs, tvecs); // 保存相机参数 FileStorage fs("camera_params.yml", FileStorage::WRITE); fs << "camera_matrix" << cameraMatrix; fs << "distortion_coefficients" << distCoeffs; fs.release(); return 0; } ``` 代码中首先读取标定图像，然后使用`findChessboardCorners`函数寻找标定板角点，将角点坐标和标定板上实际点的坐标存储在`imagePoints`和`objectPoints`中。接着使用`calibrateCamera`函数对相机进行标定，得到相机矩阵和畸变系数，并将其保存在文件中。
