Abstract针对双折射太阳敏感器多光斑和重叠光斑问题,提出一种基于椭圆拟合的高精度光斑中心提取方法。对多光斑图像进行预处理,分割出不同的目标区域;通过检测目标区域的光斑形状特征后,迅速分辨并分割重叠光斑;利用椭圆拟合法分别提取各光斑的中心坐标。仿真结果表明该方法能快速分辨重叠光斑,计算出光斑数量和半径,实现圆形和椭圆形光斑的亚像素级中心坐标提取。这种方法对光斑大小、数量没有限制,对不完整光斑也能得到较好的结果。
Other AbstractAiming at the problem of multiple and overlapping faculae of the birefringence sun sensor, a high-precision facula center extraction method based on ellipse fitting is proposed. After preprocessing for multiple facula images, different regions of interest are segmented. Then, the overlapping faculae are quickly distinguished and segmented by detecting the shape features of facula in the regions of interest. Finally, the central coordinates of each facula are extracted by ellipse fitting method. The simulation results show that the method can quickly distinguish overlapping faculae, calculate the number and radius of faculae, and extract the sub-pixel central coordinates of the circular and ellipse faculae. This method has no limitation on the size and quantity of faculae, and it can get satisfactory results for incomplete faculae.
