摘　　要：针对测量中观测的反映圆形地物形状的碎部点坐标,分别采用了直角坐标方程和参数坐标方程两种形式,通过两次平差,进行了圆的位置及大小计算,并进行了精度评定,结果表明,第一次平差的结果,两者相差较大,第二次平差的结果,两者相差不大。According to the detail point coordinate reflection of ground feature shape observed in measurement, respectively using rectangular co-ordinate equation and parameters coordinate equation two forms, through the double adjustment, made the position and size calculation of circle, and made accuracy evaluation, the results showed that the first adjustment results, both had larger differences, second adjustment results, both had little differences.

关 键 词：圆形建筑物 间接平差 直角坐标方程 参数方程
