Method of minimizing projection error when scanning and analyzing processes by camera system and apparatus for making the same

摘要

The method of minimizing projection error when scanning and analyzing processes by a camera system, according to the present invention (diagram – see Figure), is characterized in that a measuring beam (2´) is transmitted in the direction perpendicular to a plane of a scanner, parallel to a beam (1´) of a camera system shooting and the horizontal and vertical position of the camera system (1) is set such that the distance to a process plane determined by the measuring beam is minimal (Lmin). The invention also discloses an apparatus for carrying out the above-described method, wherein the apparatus is characterized in that a laser distance meter (2) is clamped, in addition to a camera system (1), on a common clamping part and the measuring beam (2´) of said laser distance meter (2) is parallel to the beam (1´) of the camera system (1) shooting.
