Device and method for recording images of objects moved on a supply device

摘要

The device has a line sensor (10) e.g. line camera, for linear scanning of objects (14) to produce image data of a surface. A camera controller (26) and a conveyor controller (30) e.g. displacement sensor and incremental sensor, determine the movement speed of the objects opposite to the line sensor or its conveyed distance. The camera controller is formed to adjust the recording frequency of the line sensor to the movement speed of the objects in such a manner that the line sensor records the image data of equidistant lines of the objects. An independent claim is also included for a method for recording of images of objects moved on a conveying device and for decoding of codes assigned to the objects.
