COLMAP开源源码
COLMAP是一种通用的动态结构（SfM）和多视图立体声（MVS）管道，具有图形和命令行界面。可以方便的对一系列二维图片进行三维重建不用对摄像机进行标定，只需要从不同角度对重建场景或物体进行拍摄得到一系列图像作为输入。(Colmap open source
COLMAP is a general-purpose Structure-from-Motion (SfM) and Multi-View Stereo (MVS) pipeline with a graphical and command-line interface. It is convenient to perform three-dimensional reconstruction on a series of two-dimensional images without calibrating the camera. It is only necessary to shoot a reconstructed scene or object from different angles to obtain a series of images as input.)
