中文摘要：

等角星图是一种特殊的星图,其保证了星空中天体运动角度的不变形,是实现室内仿真天文测量的关键技术之一。研究并提出了等角星图投影的原理,推导了投影原理公式,实现动态等角星图模拟,并通过小熊星图的模拟过程直观描述了等角星图生成流程。最后对等角星图模拟精度进行了分析。

英文摘要：

Equiangular star map is a special kind of star map,which can ensure the motion angles of the celestial objects without distortion.And it is one of the key technology to achieve the indoor simulation of astro-geodetic surveying.The principle of equiangular star map projection was studied and proposed,the formula of projection theory was derived,the dynamic equiangular star map simulating was realized,and the star map simulating process was intuitivily described through the simulation of Ursa Minor star map.The test indicated the method mentioned can realize equiangular star map simulating with a high precision.
