THREE-DIMENSIONAL DATA GENERATION DEVICE, THREE-DIMENSIONAL DATA GENERATION METHOD, AND PROGRAM

PROBLEM TO BE SOLVED: To provide a three-dimensional data generation device, a three-dimensional data generation method and a program for relatively simply searching corresponding points of two images from a stereo-image. SOLUTION: An image data input part 2 acquires image data of two images obtained by capturing a predetermined region from different positions. A position designation part 3 acquires designation points on images included in the region of one structure using the image of each of the two image data. A closed region extraction part 4 extracts a closed region including the designation points on the images of the two image data as a group of consecutive pixels whose difference in color from the designation points is within a predetermined range. An outer shape vector generation part 5 extracts outer shape vectors circulating along the outline of the closed region extracted from each of the two images. A three-dimensional data calculation part 7 assumes that the outer shape vectors of each of the two image data correspond to the outer shape of the same structure, and calculates the three-dimensional position coordinates of the outer shape of the structure from the two image data.
