按残差绝对值和最小原理的光束法区域网平差

Bundle Block Adjustment Based on the Principle of Minimizing the Sum of Absolute Residuals

本文介绍了残差绝对值和最小光束法区域网平差的原理和残差绝对值和最小解的Robust性质。在平差中,引入权以后,可以提高粗差检测的能力。实验结果表明:当区域四角的控制点上有一个点含7б_0的粗差时,均能被很好的定位。即使当四个角点均包含粗差时,其平差的精度仍具有很好的稳定性。

This paper proposes the principle of the bundle block adjustment of minimizing thesum of absolute residuals and the Robust character of its solution. After weights have beenintroduced in the adjustment, the ability of gross detection can be increased. The exper-iments show that all the four corner points contain blunders, the accuracy of the adju-stment by minimizing the sum of absolute residuals still has the best stability.
