irls_rotation_local_refiner: Failed to factorize the least squares system
这个数据是通过五目相机倾斜摄影获取的,有五个不同的镜头,不知道是否适合该算法。
This actually could happen when node indices are not consistent (something might be wrong with the input) or the view graph is not fully connected (has more than 1 connected components). Maybe you should validate your input at first. You may also want to use the function inside the graph class to detect if there are more than 1 connected components.
