摘要
外场信标光的快速捕获是空间光通信的一项重要课题。提出了一种基于外场16 km信标光的自适应阈值分割方法,同时给出了系统的设计原理。引入开小窗技术,在感兴趣区域内对信标图像进行处理,实验数据表明其有效性。
The rapid acquisition of beacon from far field is an important project of Free Space Opticalcommunication(FSO). A self-adaptive threshold algorithm is proposed, which is applied in an experiment with the range of 16 kin. The principle of system is presented as well. The gate-limited technology is introduced in the processing of interested region of the beacon image. The experiments give better results, which showed the validity of the method.
