Colmap稀疏重建部分似乎存在坐标系/尺度的不对齐 #65

作者您好，很感谢您的工作开源，当我在运行我其他代码存档中的TNT数据集时，发现MVS结果远差于您给出的TNT数据集，经过检查，我发现在您所给出的Colmap格式中，稀疏点云似乎和相机Pose没有对齐，如图所示，在Colmap中可视化，稀疏点云明显偏移了实际位置。

以下是我自己运行Colmap得到的稀疏重建结果，应该是正确的，但是使用您的代码进行MVS之后似乎结果并不好，这里是否有什么单位/格式上的区别？

Is there any people also meet this problem? It made the MVS period of my own data failed.

@Zhaoyibinn Hi, I don't know exactly how you aligned the camera pose and point cloud, is it caused by scale_factor? Maybe you can check it.
