ToF camera is used in machine vision, which can improve the detection accuracy and speed, and effectively avoid the advantages of subjectivity and individual differences brought by manual detection. The tof camera occupies an increasingly important position in the field of industrial inspection. The characteristics of tof camera used in machine vision are automation, objectivity, non-contact and high precision. Compared with image processing systems in the general sense, tof camera emphasizes accuracy and speed, as well as reliability in industrial field environments. tof camera is suitable for measurement, inspection and identification in mass production process, such as: part assembly integrity, assembly dimensional accuracy, part machining accuracy, position/angle measurement, part identification, feature identification, etc. Its largest application industries are: Automotive, Pharmaceutical, Electronics & Electrical, Manufacturing, Packaging/Food/Beverage, Medicine. Such as the inspection of the machining accuracy of the car dashboard, the rapid positioning of electronic components on the high-speed placement machine, the inspection of the number of pins, the identification of the production date on the food packaging, and the inspection of the label placement position.
In modern industrial automation production, tof cameras are involved in a variety of inspection, measurement and part identification applications, such as auto parts dimensional inspection and integrity inspection of automatic assembly, automatic component positioning in electronic assembly lines, and beverage bottle cap printing Quality inspection, barcode and character recognition on product packaging, etc. The common feature of such applications is continuous mass production and very high requirements for appearance quality. Usually this highly repetitive and intelligent work can only be done by manual inspection. We often see hundreds or even thousands of inspection workers behind the modern assembly line of some factories to perform this process. While the factory increases huge labor costs and management costs, it still cannot guarantee a 100% inspection pass rate. Sometimes, such as precise and fast measurement of tiny dimensions, shape matching, color recognition, etc., using tof camera can improve reliability and bring convenience and intelligence to industrial applications.
