Road image update using in-vehicle camera images and aerial image

Abstract

Road image is becoming important for several applications such as car navigation systems, traffic environment research, city modeling. Usually, a road image can be obtained from an aerial image but the resolution of the aerial image is often low, or it contains occlusions by obstacles. Therefore, the update of road image is required. In this paper, we propose a road image mosaicing method using in-vehicle camera images and an aerial image. We first perform image registration of road regions between these images, and then, we generate a large road image by performing image mosaicing of road regions in invehicle camera images. In an experiment, we achieved resolution improvement and occlusions removal, and also succeeded in update of a large road image.
