WebJan 1, 2015 · State-of-the-art object tracking is based on the recursive Bayes filter consisting of two parts: prediction and innovation. The prediction step models the movement of the object between two subsequent measurements in time based on an object-specific motion model (compare Sect. 2.1 ). The goal of an occupancy mapping algorithm is to estimate the posterior probability over maps given the data: , where is the map, is the set of measurements from time 1 to t, and is the set of robot poses from time 1 to t. The controls and odometry data play no part in the occupancy grid mapping algorithm since the path is assumed known. Occupancy grid algorithms represent the map as a fine-grained grid over the continuous space …
