3D Reconstruction from Multi View

Experimental code for 3D reconstruction from multi images

Methods

• Multi-View Factorization
• Euclidean Upgrading
• Bundle Adjustment

Environment setting

pip install pipenv  # If pipenv is not installed
cd <repository root path>
pipenv sync

Usage

pipenv run python euclidiean_reconstruction.py

Result

Reconstruction

The left image is the ground-truth. The middle image is the initial value estimated by the factorization method. The right image shows the initial values estimated by the factorization method and optimized by bundle adjustment.

Reprojection

The image above is a reprojection of the initial values estimated by the factorization method. The lower image shows it optimized by bundle adjustment.
