Abstract
A method may include obtaining sensor data from one or more LiDAR units and determining a point-cloud corresponding to the sensor data obtained from each respective LiDAR unit. The method may include aggregating the point-clouds as an aggregated point-cloud and generating an initial proposal for a two-dimensional ground model made of multiple grid blocks. The method may include filtering out unrelated raw data points from each grid block of the plurality of grid blocks to generate a filtered point-cloud matrix. The method may include identifying one or more surface-points and one or more object-points included in the filtered point-cloud matrix and generating an array of extracted objects based on the object-points.
