Optical capturing unit for identifying contours of objects

摘要

The detection unit has a receiving region (20) arranged over the dimension of an object (10), and a camera for generating a monochrome, analyzable image of the receiving region with the object. A regularly dispersed surface pattern (30) is arranged in the receiving region. An image processing unit has a filter adjustable to the surface pattern. The filter amplifies and/or hides the pixel corresponding to the surface pattern and the region (31) of the object not covered in the image, so that the profile (14) of the object is definable and processable.
