# StereoRectificationGridGenerator

## Brief Description

Generates two deformation fields to stereo-rectify (i.e. resample in epipolar geometry) a pair of stereo images up to the sensor model precision

Stereo

## Long Description

This application generates a pair of deformation grid to stereo-rectify a pair of stereo images according to sensor modelling and a mean elevation hypothesis. The deformation grids can be passed to the StereoRectificationGridGenerator application for actual resampling in epipolar geometry.

## Parameters

- [param] -io <string> This group of parameters allows setting the input and output images.. Mandatory: True. Default Value: "0"
- [param] -epi <string> Parameters of the epipolar geometry and output grids. Mandatory: True. Default Value: "0"
- [param] -inverse <string> This group of parameter allows generating the inverse fields as well. Mandatory: True. Default Value: "0"

## Limitations

Generation of the deformation grid is not streamable, pay attention to this fact when setting the grid step.
