Image Processing Method for Perception of Status of Approaching Vehicles Using a Camera System
Abstract:
This paper proposes an image processing method for easier perception of speed from a camera image.Vision assistance technology employing cameras is presently being put to widespread practical use. In some cases, however, the speed that is perceived from a camera image differs from that perceived from conventional side-view mirrors and the like. This is particularly apparent in the case of images taken by wide angle cameras, and it tends to cause drivers to feel a sense of incongruity. In order to reduce this sense of incongruity associated with perceiving vehicle movement in the camera image, therefore, the speed of movement of the object vehicle reflected in a conventional side-view mirror was compared with the speed of movement of the object vehicle shown in the camera image, and portions of the camera image were selectively processed to make them larger or smaller accordingly.
