大天区面积多目标光纤光谱望远镜（简称LAMOST）是一架安放在中国科学院国家天文台兴隆观测站的新类型大视场兼备大口径望远镜，即“王-苏反射施密特望远镜”。借助创新性提出的并行可控式双回转光纤定位系统，焦面板上的4000根光纤可在数分钟内将端部对准各自星象目标进行光谱观测。每一光纤单元的定位精度直接影响对应目标的光谱质量，然而目前欠缺在LAMOST观测时光纤定位精度的实时反馈以及相应错误定位光纤的走位误差补偿。本项目将以前期研究成果为基础，分析并解决现存的几个关键问题，开发一套适用于LAMOST观测时的焦面光纤定位精度检测pipeline，并将其与LAMOST观测控制系统OCS相集成，实现从焦面光纤图像采集、光纤定位精度检测、定位错误光纤单元信息反馈、光纤单元错误原因分析及错误定位光纤实时误差补偿的全自动流程，从而保障观测光谱的有效性，提高望远镜的观测效率及准确率。

The large sky area Multi-object Fiber Spectroscopic Telescope (LAMOST) is a special quasi-meridian reflecting Schmidt telescope located in Xinglong Station of national Astronomical Observatory. By using the parallel controllable fiber positioning technique, LAMOST makes reconfiguration of fibers accurately according to the positions of objects in minutes.The positional accuracy of each fiber directly determines the quality of subsequent spectrum acqusition,yet there lack the real-time optical fiber positional accuracy feedback and error compensation for mislocalized fiber units in LAMOST.Based on the previous research results, with some key problems be analyzed and solved,a novel real-time optical fiber positional accuracy detection pipeline which can be integrated in the existing observation and control system will be developed in this project. In this way,we can realize the full-automatic detection flow,in which image gather,fiber positional accuracy detection,mislocalized fiber units’ information feedback,error compensation for these detected fiber would be fulfilled as a pipeline.Furththermore,this can raise the accuracy of the acquried spectrum and optimize the telescope’s observation efficiency.
