Virtual 3D Viewpoint Control Based on Integration of Around-View and Back-View Monitors

This paper proposes a method of presenting intuitively easy-to-grasp images by merging the images of an around view monitor and a back-view monitor into a single image. In the proposed method, the viewpoint automatically changes as the vehicle moves, enabling the display of an overhead 3D image that always shows the vehicle. This video generation is composed of simple image deformation by projective transformation, which serves as a distortion correction as well as a viewpoint change. Experiments conducted in a parking situation showed that the system automatically switches the 3D viewpoint depending on the distance to the parking position to present an easy-to-understand image including the surrounding environment.
