Image processing device and image processing method to generate a plan map

摘要

An image processing device for displaying a planar map which can be easily viewed by a user without increasing the amount of processing. A planar map generating device (103) is provided with: an image acquisition section (301) for acquiring images wherein objects are imaged and the three-dimensional coordinates of the objects can be calculated; a coordinate acquisition section (302) for extracting the upper surface of a first object existing on a reference surface from the images to acquire the coordinates of the feature point of the extracted upper surface; and a first planar map generating section (303) for generating a first planar map by adjusting the size and position of the upper surface so that the values of the coordinates equivalent to the direction perpendicular to the reference surface become the same as those of the reference surface by using the acquired coordinates.
