An algorithm for the resection of imagery along the optical axis is presented to implement both of the camera calibration and resection at the same time.

提出了一种沿主光轴方向影像的单像空间后方交会方法，实现了相机检校和空间后方交会的同时进行。

In this system the axis of the camera always aims at the moving optical probe to ensure the probe imaging in the center of the image plane.

该系统中引入了一个转动平台带动相机运动，使相机光轴始终对准运动的光学测头中某一个光点，保证光学测头成像在畸变比较小的像面中心附近。
