    • PROBLEM TO BE SOLVED: To provide a surface extraction method and a surface extraction device and its program for improving the extraction precision of an object's surface. SOLUTION: In a voxel space comparted into lattice voxels, the right or wrong of the object constituting voxel, which configures the object shown in the voxel space, is detected by the voxel line, and the end of the object constituting voxel continuing in the voxel line is extracted as the object's surface. As the straight line is a unit and the intermediate part of the constituting area continuing in the straight line is ignored, even if the area which does not configure the object is present inside the object, it can be avoided that the area is mistakenly extracted as the object's surface without two or more detections of the same area.

    • There is disclosed a depth information generation apparatus capable of acquiring high-precision depth information within a short computation time. A depth information generation apparatus of this invention generates depth information at the capture position of a reference image from the reference image, and at least one peripheral image that forms a stereo image pair with the reference image, and has a high-speed stereo processor ( 30 ) for generating depth information at high speed from the reference image and peripheral image, and a high-precision stereo processor ( 40 ) for generating high-precision depth information. A motion detector ( 20 ) detects a motion in an image, and instructs an image composition unit ( 50 ) to select the output from the high-speed stereo processor ( 30 ) for a portion with a large motion, and the output from the high-precision stereo processor ( 40 ) for other portions. The image composition unit ( 50 ) composites the outputs from the high-speed stereo processor ( 30 ) and high-precision stereo processor ( 40 ) in accordance with an instruction from the motion detector ( 20 ), and outputs a depth map as final depth information.
