Pick-by-Vision

from Wikipedia, the free encyclopedia
Pick-by-vision system without position detection with display of static text and image information (left) and with infrared position detection system and dynamic optical highlighting of the storage compartment (right)

With pick-by-vision is called an innovation in logistics . For this purpose, the information is displayed to the order picker directly in his field of vision with the help of WLAN technology via data glasses . This is also known as augmented reality supported picking .

function

Pick-by-vision is the support of the order picker in warehouse logistics through visual information in his field of vision using augmented reality technology. Data glasses worn by the order picker, a so-called head-mounted display, serve as a location-independent visualization medium .

The order picker is provided with all the information required for his work task (e.g. storage location, article, removal quantity) via data glasses. The data are context-dependent, i. H. displayed depending on the place, time, field of vision and status of order processing. A position detection system (“ tracking system ”) (e.g. a camera with image recognition software) can determine the position of the order picker and his line of sight and thus include the surroundings. In addition to static text information, virtual objects can thus be displayed dynamically depending on the viewing direction. These can be arrows for navigation or a colored border around the current storage compartment. The superimposition is non-congruent, i.e. This means that real objects are not covered with exactly the same position with identical virtual objects.

The order picker must also be able to enter information online into the system behind it (e.g. warehouse management system). This primarily concerns the acknowledgment of processes and the entry of the zero crossing. These interactions take place, for example, via a touchpad on the mobile PC or by scanning barcodes or RFID tags that are located on shelves, boxes or the products to be picked. Further options for interaction are provided by dashboards or voice input . The exact structure of a pick-by-vision system depends on the particular picking system. B. the position detection system must be adapted to the work area of ​​the order picker to be covered.

Potential for companies

Most of the human information is absorbed through the optical sense. More efficient information acquisition through pick-by-vision is associated with the following potential for companies:

  • Reduction of picking errors and thus a high picking quality through a detailed visual representation (pictures of the articles, comparison of the article number in the field of vision or optical highlighting of the storage compartment) of the required information
  • Reduction of dead times and thus an increase in performance through the parallel display of different types of information (e.g. path and pick information )
  • Steep learning curve through strict process management and the display of the required data in the field of vision

Pick-by-Vision has a wide range of uses. It can be used for picking fast and slow moving items and is therefore an alternative to pick-by-voice and pick-by-light applications.

Stage of development

Pick-by-vision systems have left the research stage and are now being used productively. The previous and further establishment in the market directly with the quality and ergonomics of the data glasses . Often it is only a few weeks from kick-off to go-live; the fast implementation is due to the simple integration of the data glasses into the existing warehouse environment. Current users mainly include large production and logistics companies such as Bosch , DB Schenker and PepsiCo . The pick-by-vision solution is a perfect interplay of new technology and human movement.
