Abstract: A code scanning device for detecting an optical code on an object in a reading area, comprising a light transmitter for transmitting a reading beam, a deflection unit for periodically deflecting the reading beam over the reading area with a scanning frequency fscan, a light receiver for generating a received signal from the returning reading beam, a distance sensor for detecting a distance d from the object, and a control and evaluation unit configured to read a code content of the optical code on the basis of the received signal and to set the scanning frequency fscan as a function of the distance d.

Abstract: A camera (10) for detecting objects (48) moving relative to the camera (10) in a direction of movement (50), comprising an image sensor (18) for recording image data of the objects (48) in a camera field of view (14, 56), an optoelectronic distance sensor (24) using a time-of-flight method having a plurality of measurement zones (30a) for measuring a plurality of distance values to the objects (48) in a distance measurement field of view (58), and a control and evaluation unit (38) configured to find, by measuring distance values over a configuration time and evaluating the distance values and/or their change, a region where objects (48) move, and to automatically set a region of interest (60) for the distance sensor (24) within the distance measurement field of view (58) by determining an object region as the region where objects (48) move.

Abstract: A camera for detecting an object in a detection zone is provided that has an image sensor for recording image data, a reception optics having a focus adjustment unit for setting a focal position, a distance sensor for measuring a distance value from the object, and a control and evaluation unit connected to the distance sensor and the focus adjustment unit to set a focal position in dependence on the distance value, and to determine a distance value with the distance sensor via a variable measurement duration that is predefined in dependence on a provisional distance value such that a measurement error of the distance value and thus, on a recording of image data of the object, a focus deviation of the set focal position from an ideal focal position remains small enough for a required image sharpness of the image data.

Abstract: A method of locating code image zones in an output image of a code bearing object (14), wherein first candidates for code image zones are determined in a first segmentation process using a process of classical image processing without machine learning and second candidates for code image zones are determined in a second segmentation process using machine learning, with the first and second candidates being fused to locate the code image zones.
