More Information
Summary:The invention discloses a method and a scanner for the non-contact determination of the position and three-dimensional shape of products on a moving surface. Line scanning of a radiated and defined strip pattern (2) facilitates determining a position of an edge of each strip (5) by taking images of the line pattern (2) from a different viewing angle and determining an elevation profile along an image line (3) therefrom and by concatenating determining the 3-D elevation profile over a surface (1).
