Abstract
Techniques for determining ground surface voxels based on multiresolution planes are discussed herein. Such multiresolution planes may be generated, validated, and used to connect voxels associated with the ground. In some examples, a vehicle may use capture or otherwise receive lidar data while traversing within a driving environment. The vehicle may associate the lidar data with a voxel space. Voxels can be associated with a cell of a multiresolution grid and the vehicle may determine multiresolution planes associated with the multiresolution space. For example, the vehicle may determine a first plane associated with a first resolution level, in addition to determining a plurality of planes associated with a second resolution level. The vehicle may determine the validity of the plane(s) at the various resolution levels. Based on the validity of the planes, the vehicle may connect the valid planes that are associated with the ground surface.
