Abstract
A vehicle is provided. The vehicle includes a light detection and ranging (LiDAR) sensor to acquire point cloud information for each channel on a surrounding ground of the vehicle by using a multichannel laser. The vehicle further includes a communicator to communicate with an external server, and a processor to control the communicator to receive map data from the external server and to determine a position of the vehicle in the map data based on the point cloud information for each channel, acquired through the LiDAR sensor.
Claims18
A vehicle comprising:
- a light detection and ranging (LiDAR) sensor configured to obtain point cloud information for each channel on a surface of a surrounding ground of the vehicle using a multichannel laser;
- a communicator configured to communicate with an external server storing map data comprising the point cloud information for each channel on the surface;
- and
- a processor configured to:
- control the communicator to receive the map data comprising the point cloud information for each channel on the surface from the external server,
- identify point cloud information, matching the obtained point cloud information, among the point cloud information in the map data,
- identify an area corresponding to the identified point cloud information among a plurality of areas in the map data, and
- identify a position of the vehicle as the identified area,
- wherein the map data stored in the external server is a single-channel map data synthesizing reflectivity information for each channel of the multichannel laser;
- and
- wherein the processor is further configured to:
- synthesize the point cloud information for each channel into single-channel point cloud information, and
- match the single-channel point cloud information and the single-channel map data to identify the position of the vehicle.
A method of recognizing a position of a vehicle based on a map, the method comprising:
- obtaining point cloud information for each channel on a surface of a surrounding ground of the vehicle using a multichannel light detection and ranging (LiDAR) sensor;
- receiving map data comprising the point cloud information for each channel on the surface from an external server;
- identifying point cloud information, matching the obtained point cloud information, among the point cloud information in the map data;
- identifying an area corresponding to the identified point cloud information among a plurality of areas in the map data;
- and
- identifying a position of the vehicle as the identified area,
- wherein the map data stored in the external server is a single-channel map data synthesizing reflectivity information for each channel of the multichannel laser, and
- wherein the identifying of the position of the vehicle comprises:
- synthesizing the point cloud information for each channel into single-channel point cloud information, and
- matching the single-channel point cloud information and the single-channel map data to identify the position of the vehicle.
