What is OpenSFM?

OpenSfM is an open-source Structure from Motion library that lets you build 3D models from images, programmed in python.

It implements the whole SfM pipeline in an incremental reconstruction way:

• finding good init pairs

• bootstraping the reconstruction

• growing the reconstruction

Besides, it integrates some lightweight post-reconstruction modules including:

• undistortion

• depth map generation

• dense reconstruction

• a simple javascript-based frontend to visualize SfM result.

It uses the popular Ceres solver to tackling with non-linear optimization for bundle adjustment.

In one word, it is a great learning material of Struct from Motion.
