Advanced Topic 44 of 49 Graphics, Vision & Media
Structure from Motion
Reconstructing 3D scenes from image sequences.
How it works
SfM recovers camera poses and sparse 3D points from overlapping images using feature matching, triangulation and bundle adjustment (non-linear least squares).
Where it is used
3D scanning, photogrammetry.
Common pitfall
Needs sufficient parallax and overlap.
Where it fits in the course
Structure from Motion is topic 44 of 49 in Graphics, Vision & Media, rated Advanced. It follows Stereo Vision. The next topic is SLAM.
