Abstract

To help the walking patient avoid the mobility hazard is one of the key tasks of artificial visual prosthesis: a newly risen research project. A mobility hazard detection algorithm especially for such a system is proposed, in which a U-V-D space model is constructed for the non-hazard targets in the ground plane, so that those objects violating the model are easily identified as obstacles or pits. An iterative maximum likelihood procedure is invented to fit the model accurately and robustly with fast convergence being meanwhile accomplished.
