在空间光通信系统中，针对信标光在探测器焦平面中成像的像素数太小而导致信标光提取难度较大问题，提出采用目标预测跟踪算法实现信标光质心提取。详细介绍了基于预测跟踪的算法实现步骤及其软件实现流程，并在搭建的演示实验系统上进行了验证性实验。

英文摘要：

In space optical communication system, it is too small for the pixels number of the beacon light in the detector focal plane, and causes the beacon light extraction difficultly. So the destination forecast tracking algorithm is proposed for beacon light centroid extraction. In this paper, the implementation steps based on the forecast tracking algorithm and its sotiware flow chart are detailed, and the demonstration experiment is done based on designed system.
