摘要: 在总结现有的经纬度和QTM编码转换算法的基础上,提出了基于辅助地心坐标系的经纬度坐标与QTM编码的三向互化算法,算法以三向地理格网坐标系为出发点,从三个方向递归逼近QTM地址码。同时,提出了QTM编码精度的评价标准———转化误码率。实验证明,三向互化算法在保证速度和绝对精度的情况下,等积转换误码率为0。Abstract: Based on sumed up the current algorithm between long./lat.coordination and QTM code,a new algorithm called three orientation translating algorithm based on assistant geocentric rectangular coordinate that is used to translating algorithm between long./ lat.coordination and QTM code is presented.At the same time,in order to compare with the differences among the algorithms,a new criterion judge of precision-invert error rate.The result indicated that three orientation translating algorithm not only has good rate and absolute accurary,but also the orthembadism invert error rate is 0.
