Detection and identification of 2D codes on test tubes

To ensure test tubes are correctly sorted, a sorting machine must quickly and reliably recognize and identify the 2D code on a test tube. In this process, the W4F photoelectric sensor continuously informs the Lector61x image-based code reader when the next test tube is to be assigned to the correct patient. The combination of Lector61x and W4F ensures stable reading results, even with poor quality or slightly damaged codes. This allows for test tubes to be reliably assigned to the correct patient. Due to the increasing amount of data required for this process, the 2D code is becoming more and more important in the detection and identification of test tubes.
