A code reading unit for the parallel reading of a plurality of codes on a plurality of objects in a conveying unit is provided, wherein the code reading device has a camera unit having at least one camera head for recording an image of the objects with the codes and a control and evaluation unit that is configured to localize code regions of the codes in the image and to read the code information of the codes and to determine the position of a respective code in the image and to associate the position of a code in the image with a position in the conveying unit.

Code reading device and method for the parallel reading of a plurality of codes

A code reading device for the parallel reading of a plurality of codes on a plurality of objects arranged next to one another is provided that has a camera unit having at least one camera head for recording an image of the objects, a control and evaluation unit that is configured to localize code zones of the codes in the image and to read the code information of the codes, and a display unit to present the image and to mark the read codes and/or objects having read codes, Here a hand reading unit for reading codes is provided to subsequently read codes not read by means of the camera unit and to transfer the subsequently read code information to the control and evaluation unit.

Reading a plurality of codes

A camera apparatus is provided for detecting a stream of objects moving relative to the camera apparatus having a plurality of individual cameras that each have an image sensor for recording frames, wherein the frames overlap one another in part, having an evaluation unit for compiling frames, and having a geometry detection sensor for detecting geometrical data of the objects. The evaluation unit is here configured to generate an object image assembled from frames of an individual object of the stream of objects, with the selection of the participating frames and/or the assembly taking place on the basis of the geometrical data.

Camera apparatus and method of detecting a stream of objects

The invention relates to a method for the correction of the brightness of a raw image generated by a sensor matrix, in which an intensity matching is carried out at picture elements defined by a line coordinate and a column coordinate and at least one intensity value. The intensity matching comprises the application to the intensity values of the picture elements to be corrected of two intensity corrections independent of one another, in dependence on the line coordinate, on the one hand, and in dependence on the column coordinate, on the other hand. The invention furthermore relates to an optoelectronic sensor comprising a correction device. This correction device is matched to carry out the initially described intensity matching.

Method and device for the correction of the brightness of a raw image generated by a sensor matrix

The invention relates to a method of recognizing a code which is encoded inside an image data set which contains a piece of respective information on a gray scale value for each of a plurality of picture elements. At least one dilation operation and/or erosion operation is carried out on the image data set.

Method of recognizing a code

The invention relates to a method of reading a machine-readable barcode including a pre-determined number of code elements, in particular bars and spaces, with a respective picture being taken by means of optical imaging of at least two adjacent and/or mutually overlapping part sections of the bar code, with the individual part sections each including a code element and the part sections including in sum all the code elements of the barcode, with the pictures being stored in a data store, and with the stored pictures or parts thereof being put together for the reconstruction of the information encoded by the barcode. The invention further relates to a corresponding apparatus.

Method and an apparatus to read a barcode

A method for operating an optical sensor which has a light receptor that receives line-by-line reflected or returned light for a complete picture. At least some of the received pictures are compressed with a picture compression algorithm. To process the picture and more quickly store it in a memory-saving manner, the optoelectronic sensors compress the picture simultaneously with its receipt by the receptor. Optoelectronic sensors for use in this manner can be a code laser or a laser scanner for determining distance or generating separation pictures.

Method for operating optoelectronic sensors and sensor

A method for operating optical sensors, particularly code readers, which have a light receptor that receives light reflected and/or returned from an object. A picture is generated from the received light and the content of the picture, such as a code, is read. At least some pictures are compressed with a picture compression algorithm of the sensor. To improve the operation of such optical sensors, especially code readers, and to improve the analysis of error detection from knowing the causes for errors, only pictures which have error information are compressed and stored. The code reader is constructed to perform these functions.
