附有共线条件的航带法平差

The Polynomial Adjustment with Collinearity Condition

本文揭示了航带法平差中所存在的一些问题,由此提出了改善航带法平差的附有共线条件的航带法平差,并且对该平差方法的数学模型、法方程的结构及其解算等作了详细的分析。最后用这种平差方法对一组实测数据进行了试验,其结果表明,该平差方法不但具有运算简单,对计算机内存要求较少的优点,而且还具有较高的平差精度。

This paper,after revealing the problems existing in polynomial adjustment,introduces the polynomial ad-justment with collinearity condition(PACC) to improve the method used,and analyses the mathematic mod-el of PACC,the structure and solution of its normal equation in detail. Finally,the experiment is undertakenby using this method with a group of practical data. The result shows that the method not only has the ad-vantages of being simple in computation and requiring less memory,but also offers higher adjustment accu-racy.
