The structures are the key to advance from two-dimensional to three-dimensional automatic picture processing. Three application areas are indicated: one in semisynthetic design of materials, another in measurements of large three-dimensional industrial constructions, and the third one in robotics. There are comments on the software development needed.展开更多
