This paper proposes a surround view image generation method for vehicle camera systems. To generate an image that simultaneously provides a wide field of view and no distortion, our method uses a composite projection that combines two projection models: perspective projection and equidistant projection. This strategy can generate an image without distortion by using perspective projection near the vehicle and provides a wide field of view using equidistant projection. Our method uses a halfpipe shape model to generate an image including above the horizontal line. The experiments demonstrate the generation of surround images from parking scene images.
