An object-tracking method using a LiDAR sensor according to an embodiment includes: generating a grid map based on a point cloud generated with respect to an object using a LiDAR sensor mounted to a vehicle traveling in an x-axis direction; performing static labeling when the absolute value of the y-coordinate of the center of each grid on the grid map in a y-axis direction that intersects the x-axis direction is less than a y-axis coordinate threshold value; and performing dynamic labeling when the absolute value is not less than the y-axis coordinate threshold value. Since both static labeling and dynamic labeling are utilized, it is possible to improve the performance of outputting information about an object that is elongated, thus improving the performance of an autonomous driving system, such as prediction of a travel route and map matching.

Apparatus and method for tracking an object using a LiDAR sensor

A method of tracking an object using a LiDAR sensor includes: acquiring a point cloud using each of LiDAR sensors and clustering the point cloud. The clustering includes generating a three-dimensional (3D) grid map using the point cloud acquired by each of the LiDAR sensors; labeling voxels present in the 3D grid map with one cluster using direction points of the voxels; and checking whether it is necessary to label the voxels with mutually different clusters.

An apparatus and a method for recognizing a high-elevation structure using a LiDAR sensor are provided. The apparatus includes an object-sensing unit configured to output a point cloud, acquired by sensing an object, as LiDAR data, a point-extracting unit configured to extract points associated with a high-elevation structure, which corresponds to an object having a height greater than or equal to a predetermined level, from among points included in the LiDAR data, and an information-generating unit configured to generate the contour of the high-elevation structure and estimate the location of the high-elevation structure using the extracted points and to output the generated contour and the estimated location as information representing the high-elevation structure.

A LIDAR data clustering apparatus, a system including the same, and a method thereof are provided. The apparatus includes a processor that is configured to generate a voxel map including at least one point data based on a LIDAR and remove a road surface point from the at least one point data. The processor also clusters the at least one point data. A storage of the apparatus is configured to store data obtained by the processor and an algorithm for driving the processor.

A LIDAR data based object recognition apparatus merges segments over-segmented in a LIDAR data based segmentation process. The apparatus includes a segment generator generating a plurality of segments by grouping points acquired from a LIDAR sensor. A target segment selector selects a target segment that is a base for merging from the plurality of segments and a segment merging determination unit checks whether segments other than the target segment are mergeable segments and determines whether to merge the target segment and the mergeable segments based on attribute information of the target segment and the mergeable segments. A segment merger merges the target segment and the mergeable segments and outputs a merged segment.
