摘要
根据旋转、平移和缩放不变性、易于探测与高精度定位等原则设计出了两种用于航天器交会对接视觉测量的编码靶标。一种为圆形编码靶标,使用二进制相对编码的方法对靶标进行编码和解码。另一种为圆环形编码靶标,是一种具有坐标系的绝对编码,通过模版匹配实现解码。在不同条件下进行了实验,两种编码靶标都能被准确地识别。实验结果证明两种靶标具有很好的抗干扰性和稳定性,能够适应交会对接视觉测量的要求。
Designed two methods of coded targets used in Rendezvous and Docking by mulriple rules.One coded target was circular coded target.It was coded and decoded correspondingly by binary system.The other was annular coded target.It has a coordinate system,is coded absolutely,and is decoded by template matching.Under different conditions,two coded targets were both identified rightly.The experiment results indicate that two coded targets are steady and anti-interferential and are fit for the request of Rendezvous ...
