为了使LAMOST(大天区多目标光纤光谱天文望远镜)能够准确运转,需要对焦面板上光纤的位置进行检测和标定。在这一过程中,还需要对由前照法拍摄后所提取的光斑位置与单元实际位置进行匹配。在研究位置匹配的过程中,提出了一种经改进的以背照法[1]中的匹配方法为基础的新型匹配方法——最小值匹配法,有效地解决了原匹配方法在前照法检测过程中光斑数量众多、位置随机、计算量大等问题。实验证明,最小值匹配法的匹配正确率可满足LAMOST的使用需要。
In order for LAMOST (Large Sky Multi-Target Optical Spectrum Astronomical Telescope) to operate accurately, the position of the fiber on the focus panel needs to be detected and calibrated. In this process, you also need to match the position of the spot extracted by the foreflight method with the actual position of the unit. In the study of location matching, an improved matching method based on back-illuminated method [1], a new matching method-minimum matching method, is proposed to effectively solve the problem that the original matching method Detection of the large number of spots, the location of random, large amount of calculation and other issues. Experiments show that the matching method of minimum matching accuracy can meet the needs of LAMOST.
