Imaging-based barcode scanning method with overlapping light beams
The patent US12045689B2 outlines a method and device for an imaging-based barcode scanning system. The method involves utilizing an imaging device equipped with processing circuitry, an optical lens assembly, and light-emitting elements. The light-emitting elements are positioned laterally offset from the optical axis of the lens and are designed to project light beams that represent specific portions of a pattern. When a target barcode is within the focused region of the optical lens, these light beams overlap on the barcode's surface, facilitating accurate scanning. The system is responsive to the detection of objects, particularly barcodes, within the lens's field of view, allowing for dynamic adjustments in the projection of light beams based on the barcode's position relative to the focused region.
Additionally, the device features a fixed-focused lens and ensures that the light beams maintain consistent luminosity. The angle and lateral distance of the light beams are determined by the geometry of the lens and the focused region. The processing circuitry is capable of analyzing images captured by the image sensor to confirm the presence of barcodes and adjust the light beam projections accordingly. This innovative approach enhances the efficiency and accuracy of barcode scanning by ensuring that the light patterns are optimally aligned with the target barcodes, thereby improving the overall performance of imaging-based barcode devices.
