Abstract

Disclosed here is a system for creating maps using multispectral landscape photographed images. The system comprises surface substance analyzing means for analyzing a multispectral landscape photographed image using a spectral information database, on-ground object identifying/analyzing means for identifying an on-ground object using the surface substance analytical result and the on-ground object information database; and outputting means for outputting map information according to the on-ground object identification/analytical result and output setting.

Claims

1. A multispectral photographed image analyzing system, comprising:

an input/output processing unit for inputting a multispectral photographed image obtained by observing a plurality of wavelength bands from the sky;

a spectral information database for storing a plurality of spectral information items;

an on-ground object information database for managing on-ground object information in which each on-ground object corresponds to its spectral information included in said plurality of spectral information items; and

an analyzing unit for analyzing said multispectral photographed image,

wherein said analyzing unit uses said spectral information and said on-ground object information to identify an on-ground object in said photographed image and output the identified on-ground object through said input/output processing unit.

2. The system according to claim 1,

wherein said input/output processing unit displays said identified on-ground object clearly in said photographed image displayed on displaying means.

3. The system according to claim 1,

wherein said on-ground object information database manages information related to the shape of said on-ground object, and

wherein said analyzing unit also uses said on-ground object shape to identify said on-ground object.

4. The system according to claim 1,

wherein said on-ground object database manages information related to the circumstances of the existence of said on-ground object, and

wherein said analyzing unit also uses information related to the circumstances of the existence of said on-ground object to identify said on-ground object.

5. The system according to claim 1,

wherein said on-ground object information database manages a display attribute corresponding to a scale of display on said displaying means with respect to each on-ground object, and

wherein said input/output processing unit, when receiving a specified display scale, outputs said identified on-ground object in a format corresponding to said display attribute that corresponds to said scale.

7. The system according to claim 1,

wherein said input/output processing unit displays an analytical result output from said analyzing units on said displaying means and, when receiving an instruction of correction, updates the information in said on-ground object information database or spectral information database according to said instruction of correction.

8. The system according to claim 1,

wherein said analyzing unit converts information in said spectral information database with use of information related to the characteristics of said photographed image and uses the converted spectral information for said analysis.

9. The system according to claim 1,
