Abstract
The disclosure provides techniques for map optimization for a localization and mapping system. The map optimization method includes segmenting, based on a preset segmentation condition, a trajectory tracked by the localization and mapping system to obtain a plurality of segments of the trajectory, each segment being partitioned into a head part, an interior part and a tail part; performing a global optimization process based on frames in the head and tail parts of each segment to obtain optimized mapping results for the frames in the head and tail parts of the segment; estimating optimized mapping results for frames in the interior part of each segment based on the optimized mapping results for the frames in the head and tail parts of the segment; and updating a map built by the localization and mapping system according to the optimized mapping results for the frames in each segment.
