Image generation device, image generation method, and image generation program
First Claim
1. An image generation device comprising one or a plurality of image acquisition units which are mounted on an image acquisition unit arrangement object and which are for acquiring images, a space reconfiguration unit for mapping the captured images acquired by the image acquisition units onto a spatial model, a viewpoint conversion unit for producing viewpoint conversion image data of an image viewed from an arbitrary virtual viewpoint in a 3D space, based on spatial data obtained by the mapping by the space reconfiguration unit, and a display unit for displaying the image viewed from the arbitrary virtual viewpoint in a 3D space, based on the viewpoint conversion image data produced by the viewpoint conversion unit, further comprising:
- a distance calculation unit for calculating a distance between an image acquisition unit arrangement object model as a model of the image acquisition unit arrangement object and the spatial model, based on any of the viewpoint conversion image data produced by the viewpoint conversion unit, the captured image data expressing the captured image, the spatial model and the spatial data obtained by the mapping, wherein;
the display unit displays the image in a different manner in accordance with the distance calculated by the distance calculation unit.

Abstract
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.
