[Undergraduate Research] Car tracking and finding service in parkinglot system. Abstract: • Getting more reliable tracking results, I use image motion to enhance image-based object detection model. • Eliminating GPS localization error, I use trajectory information to reduce the white noise by Kalman Filter. • Checking parking location for finding, I fuse GPS and image localization information by driving behavior matching.
