摘　　要：赤道仪是设计用来抵消地球自转的天体追踪设备,根据调研,大多数中小学生因为传统赤道仪使用的复杂性没有将天文作为爱好坚持下去,同时赤道仪在做手动极轴校准时的过程烦琐、精度不高,也会浪费宝贵的暗夜观测时间。本项目对天文学理论、星图分析研究后,提出了一种赤道仪实现自主极轴校准的方法。通过仿真测试后,该方法能有效提高极轴校准速度与精度,能尽可能地降低天文观测与摄影的难度,推进我国天文科普工作。The equatorial mount is a device designed for tracking celestial objects to compensate for the rotation of the Earth.According to research,most primary and secondary school students fail to maintain their interest in astronomy as a hobby due to the complexity of traditional equatorial mount usage.Moreover,the cumbersome and inaccurate process of manual polar axis calibration for equatorial mounts can waste precious night observation time.After studying astronomical theory and analyzing star maps,this project proposes a method for the equatorial mount to achieve autonomous polar axis calibration.Through simulation testing,this method has been proven to effectively improve the speed and accuracy of polar axis calibration,minimizing the difficulty of astronomical observation and photography,thus promoting astronomical science popularization in China.
