Abstract
The computer main body includes a mesh size matching unit, a shading map generator, a red three-dimensional image generator, a raster image reader, a gradient reader, a floating-sinking degree reader, a first HSV converter, a mesh designator, a shading data reader, a second HSV converter, a hue reader, a first synthesis unit, a second synthesis unit, a third synthesis unit, an image output unit, a register, a color adjuster and the like, and causes the raster image RSGi having an elevation value to be viewed three-dimensionally.
Claims8
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.
