Abstract
A system and method for USS reading enhancement using a lidar point cloud. This provides noise reduction and enables the generation of a 2D environmental map. More specifically, the present disclosure provides a system and method for generating an enhanced environmental map using USSs, and the map is enhanced using a lidar point cloud. Using the lidar point cloud has advantages because the lidar point cloud is accurate and thus can provide accurate labels for training and the like.
