Abstract
Methods and devices for estimating a heading of a target vehicle are disclosed. An example method may include determining a first point cloud representative of a location of a target vehicle at a first time period and a second point cloud representative of the location of the target vehicle at a second time period. Using a computing device, an initial comparison between the first point cloud and the second point cloud may be determined based on an estimate of a speed for the target vehicle and a time difference between the first time period and the second time period. Additionally, the initial comparison may be revised based on a minimization of a distance between points of the first point cloud and corresponding points of the second point cloud. An estimate of a heading of the target vehicle may then be determined based on the revised comparison.
