Variation Based Dense 3D Reconstruction

In his master thesis,Sven Painer develops, implements, and evaluates a method to reconstruct theliver surface from monocular mini-laparoscopic sequences. The principal focus ofhis research is to create a basis for helping clinicians to write reports withquantitative descriptions of the liver surface. A Structure from Motion approachis performed to do a sparse reconstruction of the liver surface and subsequentlythis information is used in a variation based dense 3D reconstruction. Thealgorithms are formulated in a causal way, enabling the implementation to be runin real-time on an adequate hardware platform. The results show a significantperformance increase and pave the way to give clinicians a feedback duringvideo capturing to improve the quality of the reconstruction in the nearfuture.
