Summary

This chapter focused on SfM and its implementation with OpenCV's sfm contributed module and OpenMVS. We explored some theoretical concepts in multiple view geometry, and several practical matters: extracting key feature points, matching them, creating and analyzing the match graph, running the reconstruction, and finally performing MVS to densify the sparse 3D point cloud.

In the next chapter, we will see how to use OpenCV's face contrib module to detect facial landmarks in photos, as well as detecting the direction a face is pointing with the solvePnP function.

David Millán Escrivá

David Millán Escrivá

David Millán Escrivá was 8 years old when he wrote his first program on an 8086 PC in Basic, which enabled the 2D plotting of basic equations. In 2005, he finished his studies in IT with honors, through the Universitat Politécnica de Valencia, in human-computer interaction supported by computer vision with OpenCV (v0.96). He has worked with Blender, an open source, 3D software project, and on its first commercial movie, Plumiferos, as a computer graphics software developer. David has more than 10 years' experience in IT, with experience in computer vision, computer graphics, pattern recognition, and machine learning, working on different projects, and at different start-ups, and companies. He currently works as a researcher in computer vision.
