    摘要： The image generation device includes distance calculation means for calculating a distance between a space model and an imaging device arrangement object model which is a model such as a vehicle having a camera mounted, according to viewpoint conversion image data generated by viewpoint conversion means, captured image data representing captured image, a space model, or mapped space data. When displaying an image viewed from an arbitrary virtual viewpoint in the 3D space, the image display format is changed according to the distance calculated by the distance calculation means. When displaying a monitoring object such as a vicinity of a vehicle, a shop, a house or a city as an image viewed from an arbitrary virtual viewpoint in the 3D space, it is possible to display the monitoring object in such a manner that the relationship between the vehicle and the image of the monitoring object can be understood intuitionally.

    摘要： A calibration pattern unit which obtains correction information of an imaging system by imaging at the imaging system is formed by combining a plurality of three-dimensionally arranged planes. The calibration pattern unit comprises supporting members each of which has a predetermined surface corresponding to one of the planes, and a calibration pattern in which a predetermined pattern is formed on the predetermined surface of the supporting member. The supporting member can selectively set the calibration pattern unit to a first form for photographing when the correction information is obtained, and a second form for other purposes.
