Dual-imager code reader with variable illumination patterns
A recently granted patent (Publication Number: US11928546B2) discloses a novel code reader equipped with two imagers and illuminators that capture images with different field of views. The processor in the code reader determines the target distance of an object and activates the appropriate imager and illuminator pair based on whether the object is in the near field or far field. The illuminators project different patterns matching the dimensions of the field of view, allowing for the visual presentation of changing shapes depending on the active imager. This innovative technology enables the code reader to decode optical codes efficiently based on the image captured by the selected receiver pair.
Furthermore, the patent includes a method for operating the code reader, involving the selection and activation of the imager and illuminator pairs based on the target distance of the object. The method also includes analyzing the code resolution and size to determine the appropriate imager and illuminator pair for activation. Additionally, the method involves comparing the target distance with specific distance thresholds to further refine the selection process. This method ensures optimal decoding of optical codes by utilizing the unique capabilities of the code reader's dual imaging system and adaptive illumination patterns. Overall, this patented technology offers a sophisticated and efficient solution for decoding optical codes in various applications, including handheld scanners, robotic systems, and machine vision systems.
