Detection System for Optical Codes

摘要

A detection system for optical codes that are applied to an object that is conveyed through a reading field of a sensor of the detection system, wherein the detection system is configured to record a sequence of images from a respective part of the object which is present in the reading field at the respective time of recording of a respective image by means of the sensor, is characterized in that the detection system is further configured to determine a respective displacement vector between two respective consecutive images of the image sequence by means of the two respective consecutive images, wherein the respective displacement vector reflects how far an image region included in an image is displaced relative to a previous image, and with the image region also being present in the previous image.

1. A detection system for optical codes that are applied to an object that is conveyed through a reading field of a sensor of the detection system,
wherein the detection system is configured to record, by means of the sensor, a sequence of images from a respective part of the object which is present in the reading field at the respective time of recording of a respective image each having an image region, wherein the detection system is further configured to determine a respective displacement vector between two respective consecutive images of the image sequence with reference to the respective two consecutive images, with the respective displacement vector reflecting how far the image region included in an image is displaced relative to the image region included in a previous image.
