摘　　要：建立了一种基于轴角描述的光束法平差新方法。与传统基于欧拉角的光束法平差理论相比,基于轴角法在平差过程免去了大量冗杂的三角函数运算,平差模型系数矩阵和迭代过程全部采用线性运算,结构简洁。试验表明,基于轴角描述的光束法平差解算速度较快,为欧拉角平差方法的两倍左右,并且具有较好的稳定性,为影像区域网平差稳定快速求解提供了一套新方法,对于多定向参数数据快速处理具有一定借鉴价值。This paper proposed a novel bundle adjustment method based on the axis/angle expression.Compared with the traditional bundle adjustment method based on Euler angles,axis/angle expression can eliminate the redundish computation of trigonometric functions.The structure is simple for the coefficient matrix of the adjustment model and the iterative process using linear operation.Experiments have shown that the bundle adjustment speed based on axis angle method is about 2times faster than the method based on the Euler angles,and it has the advantage of robustness.This paper provides a new method for the rapid and stability of processing in the image area block adjustment solution,and this method can be a reference for the rapid process of multi-orientation parameter.
