摘要： An image generation system which generates an image including no temporal and spatial missing images, includes: a processor that executes a program; and a memory that stores the program executed by the processor. The processor calculates spectral correction parameters for transformation between a first image and a second image using the first image and the second image of different resolutions having captured the same area on the ground; calculates temporal change correction parameters for correction of temporal changes using two second images captured at different times; and generates a missing image of the first image from the second image captured at a time different from the first image using the spectral correction parameters and the temporal change correction parameters. t t TIME I------------------------------------------ ------------------ 1 SATELLITE IMAGE 1 A10(t) B11(t) L --------------------------------------------------------------------------- I -------------------------------------------------------- | SATELLITE IMAGE 2 AC(t- LOD A|(t) A|(t ) BB 2 (t) -B 20(t) NO TEMPORAL I - NO CHANGE SPECTRAL CHANGE TEMPORAL CLOUD (2) - ______ CHANGE (4) T d '2 d , dia d=2A|()Aft) dl=f,(A|(t) -A (t) ds =f2 (A 2(t)-A() (3) (5) F-------------------- --------- SATELLITE IMAGE 3 A1|(t A|(t) SIMULATE ------- B(t) B B f(t)= B|(t)+ d2+d, Af(t)=A10(t)+d3 + d B(ti)=B20(ti)+d L ----------------------------------------- SIMULATION IMAGE 0: NON-CLOUD AREA, 1: CLOUD AREA An~t)--> TIME SATELLITE IMAGE

摘要： PROBLEM TO BE SOLVED: To provide a geographical information generation system for extracting accurately a shape of a building. SOLUTION: The geographical information generation system for extracting accurately the shape of a building from an aerial photograph includes: a processor for executing a program, a memory for storing data required for executing the program, and a storage part for storing the aerial photograph. The processor detects edges of an image, based on feature quantities of adjacent pixels in the aerial photograph stored in the storage part, extracts a direction of the building by analyzing directions of the detected edges, and generates a polygon for an outline of the building, using straight lines of the extracted directions of the building.

摘要： PROBLEM TO BE SOLVED: To overcome the problems in extracting an object by spectral analysis, wherein a large error exists when using two bands (wavelengths) in conventional use, and band selection is difficult when using three bands or more, and also a conventional sensor having a narrow wavelength interval cannot be used because it cannot extract small spectral changes.
SOLUTION: A vegetated region is analyzed by detecting the amount of spectral changes (a spectrum protruding downward in detecting reflectance) from a wavelength region having a wavelength shorter than that of the RE wavelength region to the RE wavelength region and detecting the amount of spectral changes (a rising spectrum in detecting reflectance) from the RE wavelength region to a wavelength region having a wavelength longer than that of the RE wavelength region.
