First Claim
1. A vehicle search system including a server and a client, comprising:
- an image database accumulating vehicle images photographed by a stationary camera placed on the road under a condition that the vehicle images are associated with at least photographing date and time information and photographing place information of the vehicle image;
an image recognizing part for extracting feature information representing a feature of a vehicle from the vehicle image;
an image search part for selecting vehicle images from the image database, based on at least one of the photographing date and time information, the photographing place information, and the feature information, and;
a display processing part for determining similarity of the vehicle images selected by the image search part based on at least one of the photographing date and time information, the photographing place information, and the feature information, and displaying a standard image selected from the vehicle images at the most forward portion in a simulated three-dimensional space on a display and other vehicle images so that those which have higher similarity to the standard image are placed in a more forward portion by using perspective.

Abstract
A vehicle search system is provided, which is capable of easily and efficiently searching for a particular vehicle image based on vague and uncertain information. The vehicle search system includes an image database for accumulating vehicle images photographed by a stationary camera placed on the road under a condition that the vehicle images are associated with at least photographing date and time information and photographing place information of the vehicle image; an image recognizing part for extracting feature information (vehicle color, vehicle shape, etc.) from the vehicle image; an image data managing part for selecting vehicle images from the image database, based on at least one of the photographing date and time information, the photographing place information, and the feature information; and a display processing part for displaying the selected vehicle images in a two-dimensional space or a simulated three-dimensional space on a display, in an arrangement in accordance with similarity of at least one of the photographing date and time information, the photographing place information, and the feature information.

6. A computer program product in which a computer program is stored in a storage medium, the computer program being executed by a client and allowing a client computer to execute the following processing of:
-
with respect to an image database accumulating a vehicle image photographed by a stationary camera placed on the road under a condition that the vehicle image is associated with at least photographing date and time information and photographing place information of the vehicle image, making a search request from the client to the server based on at least either one of the photographing date and time information and the photographing place information; receiving vehicle images extracted from the image database in accordance with the search request and storing the vehicle images in a memory; and determining similarity of the vehicle images stored in the memory based on at least one of the photographing date and time information, the photographing place information, and feature information representing a feature of a vehicle image, and displaying a standard image selected from the vehicle images in a simulated three-dimensional space so that other vehicle images similar to each other are arranged close to each other and those which have higher similarity to the standard image are placed in a more forward portion by using perspective. - View Dependent Claims (10)
