| 摘 要： | 通过对几种典型平差方法的计算过程、算法效率、算法精度进行对比研究,表明：条件平差方法是既简单又高效的平差方法;4种平差方法的区别主要在于所选未知数的多少,参数直接决定所采用的函数模型;4种平差方法所选择的参数不同,平差精度接近,均在±2.0 mm左右.

| Abstract: | For the same adjustment case,we use different adjustment ways to calculate and analyze.By comparising the results that come from different adjustment ways,research shows that the conditional adjustment way is the best way for the given case because of the simple procedure and the high precision. Although the different parameters and different models for each adjustment way,the adjustment precision for each way is nearly the same level,the result is about±2.0 mm. |
