在航空航天技术的具体应用中,星相机是一种重要的卫星姿态设备,其通过拍摄稳定恒星的图像来获取卫星的高精度姿态信息,从而实现卫星姿态的精确控制。因此,基于星相机的卫星姿态计算算法就成为了星敏感器研究的重要内容。为了实现卫星姿态的高精度计算,文中参考并分析了大量的文献,修改了Top-hat变换,并设计出了一个高可靠度、高精度的卫星姿态计算方法。通过数据实验分析证明,该算法可以用于星点提取,实现了3“~9”的高精度姿态计算。
In the specific application of aerospace technology, the satellite camera is an important satellite attitude device, which acquires the high-precision attitude information of the satellite by photographing the stable stars, so as to realize accurate control of the satellite attitude. Therefore, satellite camera attitude calculation algorithm has become an important part of star sensor research. In order to realize the high-precision calculation of satellite attitude, a large number of references have been referenced and analyzed in this paper, the Top-hat transform has been modified, and a high-reliability and high-accuracy satellite attitude calculation method has been designed. Experimental results show that this algorithm can be used in star point extraction and realize high precision attitude calculation from 3 to 9.
