  • Publication number: 20190019086
    Abstract: An optoelectronic code reader (10) having at least one light receiving element (24) for generating image data from reception light and an evaluation unit (26) with a classifier (30) being implemented in the evaluation unit (26) for assigning code information to code regions (20) of the image date, wherein the classifier (30) is configured for machine learning and is trained by means of supervised learning based on codes read by a classic decoder (28) which does not make use of methods of machine learning.

  • Publication number: 20160104337
    Abstract: 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.

  • Patent number: 9270892
    Abstract: An optoelectronic device (10) is provided having an image sensor (20) for generating pixel images of a detection area (12) and a brightness correction unit (28) configured to modify brightness values of the pixels with a correction factor (Hmul) to obtain a more homogeneously illuminated image. A respective correction factor (Hmul) is calculated for individual pixels or groups of pixels from a perspective transformation (M) which converts geometries of an object plane (34) in the detection area (12) into geometries of the image plane (32).

  • Patent number: 9047519
    Abstract: An optoelectronic apparatus is set forth for measuring structural sizes or object sizes which has a light reception element for converting received light into image data, a reception optics arranged before the light reception element as well as an evaluation unit which is configured to identify structures or objects in the image data, to determine its dimensions in picture elements and to convert the dimensions into absolute, in particular metric, units of length with reference to a scaling factor, wherein the scaling factor can be determined in a calibration procedure. In this respect, the evaluation unit is configured to locate code regions in the image data and to read out code information from the code regions and to calculate the scaling factor during the calibration procedure from dimensions of a calibration code whose code information includes a size indication for the calibration code in the absolute units of length.

  • Patent number: 9008426
    Abstract: A camera system (10) is provided for generating an image presegmented into regions (106a-b) of interest and of no interest, having an evaluation unit (20) which is designed to divide the raw image into part regions (106a-b) to calculate a contrast value for each part region (106a-b) and to decide with reference to the contrast value whether the respective part region (106a-b) is a region of interest (106a) or a region of no interest (106b). In this respect, the evaluation unit (20) has a preprocessing unit (22) which is implemented on an FPGA, which respectively accesses the pixels of a part region (106a-b) and generates summed values (a), b) for the respective part region (106a-b) and has a structure recognition unit (24) which calculates the contrast value of the part region (106a-b) from its summed values (a, b) without accessing pixels of the part region (106a-b).

  • Patent number: 8910866
    Abstract: A code reader (10) having an image sensor (20) for the generation of images of a detection zone (12) resolved into pixels is provided having a decoding unit (24) in order to identify code regions (14) in the images and to readout their coded information, as well as having a verification unit (28) for evaluating the code quality in accordance with predefined criteria. In this connection the verification (28) is configured to initially generate a normalized verification image of the code from the code regions (14) by means of image processing for the verification.
