碩士 === 國立交通大學 === 資訊科學與工程研究所 === 95 === In this thesis, a real-time parking assistance system, which provides a top-view video for a driver to refer to, is investigated. Unlike other parking assistance systems that use special equipments or multiple sensors, the system only uses a rear-view camera to capture scene images behind a backing car. The rear-view images are then converted to top-view ones of the vehicle and its surrounding area using homography transformations. Thus, the driver can easily observe relative positions between the vehicle and the parking area. Moreover, a sequence of top-view images can be further synthesized to generate a single, size-extended one by feature point tracking and image registration. Hence, the system is able to display surrounding area outside the current camera view. By using the proposed system, the driver can have a more clear sense of distance and direction for easier and faster parking in a garage or on the street.
