Title:
MAP CONSTRUCTION METHOD AND DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/011557
Kind Code:
A1
Abstract:
A map construction method, comprising: according to a first probability and the distance of each pixel point, obtaining a second probability that each pixel point belongs to an obstacle; according to the second probability and position information, determining a voxel corresponding to each pixel point; generating a three-dimensional probability map at a current moment according to the voxels; according to a preset adjustment parameter, updating a probability value of each voxel in the three-dimensional probability map at a previous moment; multiplying the probability value of each voxel in the three-dimensional probability map at the current moment by the updated probability value of the corresponding voxel in the three-dimensional probability map at the previous moment; and, according to the multiplication result, updating the probability value of each voxel of the three-dimensional probability map at the current moment.
