Abstract
An embodiment LiDAR free space data generator includes a point filter module configured to select input points in a region of interest of an autonomous parking system from a three-dimensional (3D) point cloud obtained from a LiDAR, a two-dimensional (2D) grid map generation module configured to perform 2D grid-wise point processing on the selected input points to generate a first occupied grid feature map, and a multi-modal noise filter module configured to perform grid-level noise filtering, grid-level downsampling, or point-level noise filtering on the first occupied grid feature map to generate first LiDAR free space data.
