ABSTRACT:
Selecting of particular image lines for composition of range image such that a composition and evaluation of range image is possible in real time actually corresponds to the imaging of a TV or video camera. The image field is scanned column by column and the contents of the column (all lines) are read in parallel. After digitizing the content of the column, a selection logic selects a particular imaging dot within each of the columns. Using the principles of triangulation, the line position of the dot selected is identified by a multibit binary data word is vertical position in representation of the distance from the camera or the light strip source.
