Abstract
A system may receive a sensor dataset representing an environment and use the dataset to create or update a map. In creating or updating the map, the system may determine an object classification of one or more detected objects and only selectively incorporate data into the map based at least in part on the classification. The map may be associated with the classification (or semantic) information of the objects, as well as weights based on the classification. Similarly, datasets with selected classes of data removed may be used for system localization. Further, the system may determine an object track of the objects. When updating the map, voxels in a voxel space may indicate an occupied voxel based on a threshold number of observances. The object track and clean map can then be used for controlling an autonomous vehicle.
