An apparatus (), in particular a code reader, for the taking of undistorted images of a surface of objects () moved on a conveying device () is set forth, wherein the apparatus () has a geometry detection sensor () which is made for the detection of the geometry of the objects () with reference to spacing data and/or to the remission behavior of the objects () as well as a line sensor (), in particular a line camera, which can scan the objects () linewise for the generation of image data of the surface in a linear reading window () which forms an angle with the conveying direction. In this connection, a control () is provided which is made to generate, on the basis of geometrical data of the geometry detection sensor (), a respective spacing profile of the surface over the reading window () from the perspective of the line sensor () and to generate an associated zoom factor and/or a taking frequency for the line sensor () from each spacing profile; to set the line sensor () to the associated zoom factor and/or to the taking frequency for the respective line of the objects () to be scanned; and to compose the image data thus taken linewise in an undistorted manner to form a uniformly resolved total image of the surface.

Taking undistorted images of moved objects with uniform resolution by line sensor

An apparatus, in particular a code reader, for the recording of images of objects () moved on a conveyor device (), wherein the apparatus includes a line sensor (), in particular a line camera, which can scan objects line wise for the generation of image data of the surfaces, as well as a speed determination device (), which can determine the speed of movement of the objects () with respect to the line sensor () or their conveyed distance. At the same time an evaluation unit () is provided, which is adapted to match the recording frequency of the line sensor () to the speed of movement.

Apparatus and method for the recording of images of objects moved on a conveyor device

The invention relates to an apparatus and a method for the sensing of objects moved through the field of view of an optical sensor comprising a device for the selection of regions of interest which are each associated only with a part of the field of view of the optical sensor, wherein a distance measurement device and/or a remission measurement device is/are integrated into the optical sensor or is/are connected in front of it or after it in the direction of movement of the objects, with the distance measurement device and/or the remission measurement device being designed for the determination of the spacing and/or of the remission of the object surfaces facing the distance measurement device and/or the remission measurement device and being coupled to an evaluation circuit for the calculating of the regions of interest in dependence on the determined spacings and/or remissions.

Apparatus and method for monitoring moved 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.
