Latest Patents

Won-Sang Ra holds a patent titled "Method of simultaneously estimating movement and shape of target vehicle using preliminary distribution model of tracklet." This method provides a high level of reliability in estimation performance, even when there is a change in the heading of the target vehicle. The approach utilizes a preliminary distribution model defined by a small number of representative tracklet appearance points. It employs a tracklet defined in an orthogonal coordinate system and establishes a linear correspondence relationship between the preliminary distribution model of the tracklet and the central position of the target vehicle. The method also involves performing many-to-one data association between tracklet outputs, which is executed by a signal processing device that processes signals emitted from multiple radars mounted on a host vehicle.
