Quasi-perspective projection with applications to 3D factorization from uncalibrated image sequences
15 years 12 months ago
The paper addresses the problem of factorization-based 3D reconstruction from uncalibrated image sequences. We propose a quasi-perspective projection model and apply the model to ...
