| 摘 要： | GPS车载导航系统现在已经运用得十分广泛,然而GPS采用的是WGS-84坐标系,目前我国的各类地图均采用54北京坐标或是80西安坐标,两者的差距可达0～120m.要使用各类电子导航装置就需要把WGS-84坐标转换到54北京坐标系下,并和电子地图中的像素点对应起来.本文主要介绍一种坐标转换算法,并且通过实测检验,证实算法效果良好.

| Abstract: | Vehicle-borne GPS navigation system has found wide applications and it uses WGS-84 coordinate system.But Chinese maps adopt 54 Beijing Coordinate System or 80 Xi'an Coordinate System.The difference between the GPS maps and the Chinese maps can reach 0-120m.Therefore electronic maps can be used by various navigation devices only after its WGS-84 coordinate system is transformed into the 54 Beijing Coordinate System and their map pixels have to be made correspondent to each other.This paper introduces a coordinate transform algorithm.Measured test data verify its effectiveness. |
