Machine vision for logistics and intralogistics
From goods receipt and storage through picking and sorting to dispatch, machine vision supplies the data that automated logistics processes depend on.
Cameras and code readers identify goods, read barcodes and text, measure parcels and support robots in gripping and sorting.
Barcode and 2D code reading
Image-based code readers capture:
- 1D barcodes
- DataMatrix
- QR codes
- several codes at once
Depending on the application, codes must be read reliably even with:
- high conveyor speeds
- varying position
- different orientation
- large fields of view
OCR and plain-text recognition
Alongside codes, cameras can recognize printed information such as:
- shipment numbers
- addresses
- part numbers
- markings
Goods receipt
Cameras can process incoming goods:
- identify them
- categorize them
- measure them
- check them for damage
- assign them to a storage process
Parcel and volume measurement
3D cameras allow the automatic determination of:
- length
- width
- height
- volume
- position
of parcels and other objects.
Sorting
Code or object data that has been read can be used directly to control sorting systems.
Order picking
2D and especially 3D cameras help robots locate products and determine suitable gripping positions.
Palletizing and depalletizing
3D vision supports:
- parcel localization
- height determination
- grip point calculation
- load optimization
AMR and AGV
3D cameras can also be used on mobile robots for:
- navigation
- obstacle detection
- environment capture
