Claim Text:
1. A raster image three-dimesionalization processing device, comprising: a first storage configured to store Digital Elevation Model (DEM) data; a second storage configured to store a raster image of a region where the DEM data is obtained; a display; and a processor, including (A) a unit configured to match a mesh size of the DEM data with a mesh size of the raster image; (B) a unit configured to obtain an above-ground opening image, an underground opening image, and a slope emphasis image in which a more enhanced color is allocated for a larger gradient value, from the DEM data, and obtain a three-dimensionally visualized image which combines these images; (C) a unit configured to read a floating-sinking degree which is a parameter when the above-ground opening image and the underground opening image are obtained, and read a gradient when the slope emphasis image is obtained; (D) a first hue-saturation-value (HSV) conversion unit configured to convert the floating-sinking degree and the gradient into brightness (Va) and saturation (Sa), respectively, while fixing hue (H) to “0”, and output a conversion result as a first conversion image; (E) a second HSV conversion unit configured to subject the raster image to HSV conversion and output a conversion result as a second conversion image; (F) a unit configured to read the hue (H) of the second conversion image and obtain a first color composite image which combines this hue (H) and the first conversion image; and (G) a unit configured to generate a second color composite image which combines the first color composite image and the second conversion image, and display the second color composite image on a screen of the display.
