可以通过 cv::Rodrigues(rotation_vector, rotation_matrix) 函数将旋转向量转换为旋转矩阵,或者通过 cv::composeRT(rotation_vector, translation_vector, camera_rotation, camera_translation, camera_rotation_matrix, camera_translation_matrix) 函数将旋转向量和平移向量组合成变换矩阵。

第二个参数imagePoints,为每一个内角点对应的图像坐标点。和objectPoints一样,应该输入vector<vector<Point2f>> image_points_seq形式的变量; 第三个参数imageSize,为图像的像素尺寸大小,在计算相机的内参和畸变矩阵时需要使用到该参数; 第四个参数cameraMatrix为相机的内参矩阵。输入一个Mat cameraMatrix即可,如Mat ...
