The present invention refers to a method for removing non-relevant points of a point cloud (22) corresponding to a point representation of an environment (20) of an ego vehicle (10) with multiple individual points (24), comprising the steps of providing the point cloud (22) covering a position of the ego vehicle (10), recognizing the environment (20) of the ego vehicle (10) using at least one environment sensor (14) of the ego vehicle (10), determining a current position of the ego vehicle (10) within the point cloud (22) based on the recognition of the environment (20) of the ego vehicle (10), determining a projection area (32) with a projection of the ego vehicle (10) into the point cloud (22) based on the determined current position of the ego vehicle (10), and removing individual points (24) from the point cloud (22) in the projection area (32) of the ego vehicle (10) as non-relevant points. The present invention also refers to a driving support system (12) comprising at least one environment sensor (14) for recognizing an environment (20) of an ego vehicle (10) and a processing unit (16), which receives sensor information from the at least one environment sensor (14) via a data connection (18) and processes the sensor information, wherein the driving support system (12) is adapted to perform the above method.
