摘要
为提高部分不确定性平差模型的解算效率,直接采用迭代算法进行求解。讨论了迭代不收敛时的解算方法。算例表明,该部分不确定性平差模型的迭代算法是可行的,解算效率更高、稳定性更好。
In order to improve the calculation efficiency of the adjustment model with part uncertainty, a di- rectly iterative algorithm is developed. Another algorithm is also discussed when the iterative algorithm is di- vergent. The results of a straight line fitting and a plane coordinate transformation illustrate that the proposed algorithm for adjustment model with part uncertainty can be practiced, has higher calculation efficiency, and has improved stability.
