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:
- Estimation of displacements grids for epipolar geometry transformation
- Epipolar resampling of the image pair using those grids
- Dense disparity map estimation
- Projection of the disparities on a Digital Surface Model (DSM)
Let’s go to the third dimension!
