Project

This project is based on the paper Towards an efficient 3D model estimation methodology for aerial and ground images which was published at Machine Vision and Applications Journal (2017). This code implements a Structure-from-Motion reconstruction pipeline described in the paper mentioned.

Laboratory

Dependencies:

• OpenCV
• Ceres Solver
• OpenMVG
• Exiv2

Please install those libraries before compiling the code

Usage:

1. Put the sfm_params.txt file in a desired location and change the image dataset path for the desired one.
2. Create a directory inside the image path called 'result'
3. Inside the 'result' dir, create the directories 'txt' 'visualize' 'models' 'undistorted'
4. You can change the sfm_params.txt parameters according one's needs
5. Call "./VerlabSFM [path_to_sfm_params] 1" for image registration and "./VerlabSFM [path_to_sfm_params] 2" for camera pose and sparse structrure estimation.

Obs: For fisheye distorted images (like ones taken with a GoPro) it is strongly recommended to calibrate the images and remove the distortion before using this pipeline on them.
