Abstract

A Local search device includes a camera module for taking a photo an image and acquired image information; a positioning module, a directional measurement module and an view field angle information acquisition module for acquiring location information of its own, direction information of photo and field angle of view information at a time when said camera module photographs an image, respectively; an information processing module for storing and processing information including said image information, said location information of its own, said direction information of photo and said field angle of view information; and an image display module for indicating said stored image information, wherein said information processing module determines, from said location information of its own, said direction information of photo and said field angle of view information acquired and stored when said camera module has photographed an image, a direction range fitting into a photographed image-plane of said photographed image, and extracts a target object existing within said direction range and data associated with said target object from a database, and wherein, in an image indicated when said stored image information is displayed on said image display module, data associated with said extracted target object is indicated corresponding to a place where said target object is located.

Claims

1. A local search device, comprising;

a camera module photographing an image and acquiring image information;

a positioning module, a directional measurement module and an view field angle information acquisition module acquiring location information of its own, direction information of photo and field angle of view information at a time when said camera module photographs an image, respectively;

an information processing module storing and processing information including said image information, said location information of its own, said direction information of photo and said field angle of view information; and

an image display module indicating said stored image information, wherein

said information processing module determines, from said location information of its own, said direction information of photo and said field angle of view information acquired and stored when said camera module has photographed an image;

a direction range fitting into a photographed image-plane of said photographed image, and extracts a target object existing within said direction range and data associated with said target object from a database, and wherein,

in an image indicated when said stored image information is displayed on said image display module, data associated with said extracted target object is indicated corresponding to a place where said target object is located.

2. The local search device according to claim 1, wherein visual recognition information of a target object in an image is collated with visual recognition information associated with a target object extracted from a database, said visual recognition information being extracted by analyzing said image acquired by said camera module, and, when a target object with same visual recognition information is detected, data associated with said target object is indicated in a position in said image corresponding to a position where said target object is indicated.

3. The local search device according to claim 1, wherein associated data is indicated only for a target object existing in a designated particular region of said image indicated on said image display module.

4. The local search device according to claim 1, wherein a distance range for searching for a target object is set corresponding to said field angle of view information, and data associated with a target object existing within said set distance range among target objects extracted from a database is indicated.

5. The local search device according to claim 1, wherein three-dimensional map data within said direction range is extracted from a database, and said extracted three-dimensional map data is made correspond to said image indicated on said image display module, and wherein,

when an place where an optional target object is located is designated in said image, corresponding data associated with said target object in said three-dimensional map data is indicated.

6. An local search method, comprising:

a procedure of taking photograph of photographing an image and acquiring image information;

a positioning procedure, a directional measurement procedure and an view field angle information acquisition procedure of acquiring location information of its own, direction information of photo and field angle of view information at a time when an image is photographed, respectively;

an information processing procedure of storing and processing information including said image information, said location information of its own, said direction information of photo and said field angle of view information; and

an image display procedure of indicating said stored image information, wherein,

from said location information of its own, said direction information of photo and said field angle of view information acquired and stored when an image has been photographed in said photographing procedure, a direction range fitting into a photographed image-plane of said photographed image is determined, wherein

a target object existing within said direction range and data associated with said target object is extracted from a database, and wherein.

in an image indicated when said stored image information is displayed, data associated with said extracted target object is indicated corresponding to a place where said target object is located.

7. The local search method according to claim 6, wherein visual recognition information of a target object in an image is collated with visual recognition information associated with a target object extracted from a database, said visual recognition information being extracted by analyzing said image acquired in said photographing procedure and, when a target object with same visual recognition information is detected, data associated with said target object is indicated in a position in said image corresponding to a position where said target object is indicated.

8. The local search method according to claim 6, wherein associated data is indicated only for a target object existing in a designated particular region of said indicated image.

9. The local search method according to claim 6, wherein a distance range for searching for a target object is set corresponding to said field angle of view information, and data associated with a target object existing within said set distance range among target objects extracted from a database is indicated.

10. The local search method according to claim 6, wherein three-dimensional map data within said direction range is extracted from a database, and said extracted three-dimensional map data is made correspond to said indicated image, and wherein,

when an place where an optional target object is located is designated in said image, corresponding data associated with said target object in said three-dimensional map data is indicated.
