On-axis aimer and distance measurement apparatus for vision system
A recently granted patent (Publication Number: US11966811B2) discloses an apparatus designed for automatically focusing a reader within a vision system. The apparatus includes an optics assembly with at least one lens and an image sensor, an on-axis aimer and distance measurement assembly with a light source, receiver, reflecting assembly, and processor device. The reflecting assembly, comprising at least two elements, is positioned in front of the lens to direct light beams and reflected light coaxially with the reader's optical axis. The processor device utilizes the reflected light to determine the distance between the lens and the object, enabling precise focusing of the lens based on this information.
Furthermore, the patent includes an on-axis aimer and distance measurement apparatus for a vision system, incorporating a light source, reflecting assembly, receiver, and processor device. The reflecting assembly, consisting of at least two elements, directs light beams and reflected light along different axes to determine the distance between the lens and the object. The processor device controls various parameters of the vision system for image acquisition based on the determined distance, including aperture size, focus, and magnification. Additionally, the apparatus can identify object movement, adjust the system accordingly, and even provide 3D information by utilizing multiple image sensors and acquired images. The method outlined in the patent involves projecting light beams, determining distances, adjusting lens focus, and acquiring images of symbols on objects, showcasing a comprehensive and innovative approach to vision system functionality.
