4.6 Stereoscopic reconstruction from VHR optical images pair

This section describes how to convert pair of stereo images into elevation information.

The standard problem of terrain reconstruction with available OTB Applications contains the following steps:

Let’s go to the third dimension!

  4.6.1 Estimate epipolar geometry transformation
  4.6.2 Resample images in epipolar geometry
  4.6.3 Disparity estimation: Block matching along epipolar lines
  4.6.4 From disparity to Digital Surface Model
  4.6.5 One application to rule them all in multi stereo framework scheme
  4.6.6 Stereo reconstruction good practices
  4.6.7 Algorithm outline
