Publication number: 20240027622Abstract: A method for reconstructing surface topology of a ground surface in an environment of a vehicle. The reconstruction is based on LIDAR sensor scan data. A virtual horizontal grid is defined for dividing the environment into distinct grid cells. In each grid cell, a local tile is defined as a function of coordinates of those measurement points that are contained in the respective grid cell. The respective local tile of each individual grid cell is classified as belonging to the ground surface based on reference surface data that identifies the respective local tile of at least one grid cell as a ground surface tile. For at least some grid cells, a respective height value of the measurement points in that grid cell is re-calculated as being the vertical distance of the respective measurement point above the ground surface, as it is defined by the identified ground surface tiles.Type: ApplicationFiled: November 25, 2021Publication date: January 25, 2024Inventors: Francesco Ferroni, Ohad Menashe
