WebMar 13, 2024 · 具体来说，假设相机的位姿已知，并且已经标定了相机的内部参数，可以使用OpenCV中的`cv2.projectPoints()`函数将三维世界坐标系中的点投影到二维图像平面上，然后可以通过像素坐标计算出相机与物体之间的距离。 具体的步骤如下： 1. WebThe function computes a decomposition of a projection matrix into a calibration and a rotation matrix and the position of a camera. It optionally returns three rotation matrices, one for each axis, and three Euler angles that could be used in OpenGL. The function is based on RQDecomp3x3 () .
