Lidar object detection system for automated vehicles
View Patent ↗An object-detection system suitable for an automated vehicle includes a lidar and a controller. The lidar is used to detect a point-cloud that is organized into a plurality of scan-lines. The controller is in communication with the lidar. The controller is configured to classify each detected point in the point-cloud as a ground-point or a non-ground-point, define runs of non-ground-points, where each run characterized by one or multiple instances of adjacent non-ground-points in a scan-line separated from a subsequent run of one or more non-ground-points by at least one instance of a ground-point, define a cluster of non-ground-points associated with the object. The cluster is characterized by a first run from a first scan-line being associated with a second run from a second scan-line when a first point from the first run is displaced less than a distance-threshold from a second point from the second run.
1. An object-detection system suitable for an automated vehicle, said system comprising:
a lidar used to detect a point-cloud indicative of an object proximate to a host-vehicle, said point-cloud organized into a plurality of scan-lines;
a controller in communication with the lidar, said controller configured to
classify each detected point in the point-cloud as a ground-point or a non-ground-point,
define runs of non-ground-points, each run characterized by one or multiple instances of adjacent non-ground-points in a scan-line separated from a subsequent run of one or more non-ground-points by at least one instance of a ground-point,
define a cluster of non-ground-points associated with the object, said cluster characterized by a first run from a first scan-line being associated with a second run from a second scan-line when a first point from the first run is displaced less than a distance-threshold from a second point from the second run.
