Comparision of the height accuracy obtained from efp bundle adjustment and forward intersection using simulation space photogrammetric data 法光束法平差与直接前方交会计算高程的精度比较
The aim of projective reconstructing is to estimate the position and direction of cameras through matching points in different images so lay the foundation for further reconstructing . on the basis of current methods of projective reconstructing , we used the levenberg - marquardt method to optimize the result of linear method so the precision is be improved , and we use the bundle adjustment method to entirely optimize the structure of scene and projective matrixes 本文在研究已有射影重建算法的基础上,利用l - m算法对基于基础矩阵的射影重建算法得到的线性结果进行优化,提高了算法的估计精度和稳定性,并在求得所有图象对应的投影矩阵后利用bundleadjustment方法对空间结构及投影矩阵进行全局优化。
Given a set of images depicting a number of 3D points from different viewpoints, bundle adjustment can be defined as the problem of simultaneously refining the 3D coordinates describing the scene geometry as well as the parameters of the relative motion and the optical characteristics of the camera(s) employed to acquire the images, according to an optimality criterion involving the corresponding image projections of all points.
