SYSTEM AND METHOD FOR DETECTING AN OBSTACLE IN AN AREA SURROUNDING A MOTOR VEHICLE

Filed:2021-06-07Pub:2023-08-17
Applicant:RENAULT S.A.S

The invention relates to a detection method implemented in a vehicle for detecting the presence of an obstacle in an area surrounding the vehicle from data from a perception system comprising:—a LIDAR configured to perform a 360° scan of the area surrounding the vehicle;—five cameras, each of the cameras being configured to capture at least one image (I 2 , I 3 , I 4 , I 5 , I 6 ) in an angular portion of the area surrounding the vehicle; the method being characterised in that it comprises:—a step ( 100 ) of scanning the area surrounding the vehicle by means of the LIDAR to obtain a point cloud ( 31 ) of the obstacle;—for each camera, a step ( 200 ) of capturing an image (I 2 , I 3 , I 4 , I 5 , I 6 ) to obtain a 2D representation of the obstacle located in the angular portion associated with the camera;—for each captured image (I 2 , I 3 , I 4 , I 5 , I 6 ), a step ( 300 ) of assigning the points in the point cloud ( 31 ) corresponding to the 2D representation of the obstacle to form a 3D object ( 41 );—a step ( 400 ) of merging the 3D objects ( 41 ) making it possible to generate a 3D map ( 42 ) of the obstacles all around the vehicle;—a step ( 500 ) of estimating the movement of the obstacle from the generated 3D map ( 42 ) and GPS data ( 43 ) of the vehicle to obtain information ( 44 ) on the position, size, orientation and speed of the vehicles detected in the area surrounding the vehicle.
