OpenMVG Scene initializer for Elphel non central camera.

=========================================== main_openMVG_SfMImageListing_Elphel_Camera

Introduction

This binary help to initialize a OpenMVG sfm_data's scene for non central Elphel's cameras.

It parses an image directory and initialize the camera subpose for each camera intrinsic (openMVG::cameras::Pinhole_Intrinsic_Subpose) by using the Elphel calibration X.key file. Note that since that non central camera are used, many Views share the same Pose index.

Building

Since this project depends on OpenMVG/OpenGV, you must compile them and install them. Here the step by step build instructions:

mkdir myProject
cd myProject

openmvg_sfmimagelisting_elphel_camera's Issues

using only some of the images from the Eyesis-4pi camera

Hi Pierre,

Could you please implement a filter to specify only some images from Eyesis-4pi to be used in the reconstruction (for example the two stereo-pairs) ?

Also, since all intrinsic & extrinsic parameters of the rig are known how to disallow OpenMVG to adjust them later during the pipeline ?
Regards.
