| Abstract: | In order to improve the calculation efficiency of the adjustment model with part uncertainty, a directly iterative algorithm is developed. Another algorithm is also discussed when the iterative algorithm is divergent. 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. |
