This talk will give an overview of the film production processes, focusing on high quality 3D reconstruction of the scene and how GPU acceleration applies to it, as well as the math and algorithms behind. Several solutions for accelerating the algorithms involved in the 3D reconstruction process exist, but very few are concerned with the online quality assessment of the reconstructed areas. This is mostly due to the computational load of the algorithms computing the error in the reconstruction. The presented approach proposes efficient solutions based on GPU implementation of the matrix operations involved. It differs from the existing solutions by exploiting the inherent sparse, block structure of the underlying system matrices. The work is part of the EU FP7 IMPART project.
