A method of detecting a ground that is performed by a ground detection device is provided. The method includes arranging points obtained from a lidar sensor in a plurality of cells included in a circular grid map, generating a profile value for each of the plurality of cells using heights of the points; and detecting around points arranged in each of the plurality of cells using the profile values.

Method for detecting ground using lidar sensor and ground detection device performing same

An object shape detection method. The method includes determining an area estimated as one object from scanning information obtained by scanning around the moving object; obtaining line information of the one object; generating pattern shapes each of which one side includes at least part of the line information; and selecting a representative pattern shape of the one object corresponding to a shape of an object by using the scanning information.

Object shape detection apparatus and method

A method of detecting a tunnel or an overpass performed by a tunnel detection apparatus. The method includes obtaining multi-layer data divided up and down from a LiDAR sensor and detecting entry or exit of the tunnel or the overpass around a moving object on which the tunnel detection apparatus is mounted based on distance information indicated by each of at least some layer data among the multi-layer data.

Method of detecting tunnel and overpass by using lidar sensor and apparatus therefor

A method for detecting a crosswalk using a crosswalk detection device is provided. The method includes acquiring point data around a lidar sensor from the lidar sensor, detecting one or more crosswalk points among a plurality of points included in the point data based on intensities of the plurality of points; and detecting the crosswalk based on positions of the detected crosswalk points.

Method for detecting crosswalk using Lidar sensor and crosswalk detection device for performing the method

A method for detecting a traffic sign using a traffic sign detection device is provided. The method includes acquiring point data from a lidar sensor detecting a vicinity of the lidar sensor; clustering a plurality of points based on positions of the plurality of points included in the point data; determining one or more plane object clusters, each of which corresponds to a plane object, among one or more clusters, each of which is formed by clustering the plurality of points; and detecting one or more traffic sign object clusters, each of which corresponds to the traffic sign, among the one or more plane object clusters based on a predetermined traffic sign detection factor.
