Real-Time 3D Inspection Using Scalable Off-the-Shelf Sensors

Universal Robotics has combined automated multi-dimensional inspection with automated intelligence to provide 2½D, 3D, 4D (color) and Multi-D inspection of random objects in large areas for a wide range of real-time logistics applications. Powered by Spatial Vision Inspection, the software accurately identifies and tracks objects that are difficult to see or change shape, such as bags. Since the software is capable of integrating with any sensor appropriate for the job, sensors may be one-half the cost of traditional approaches. Spatial Vision Inspection excels at recognition and examination of large complex objects – up to a 60 inch (~1,500mm) cube in size. It does it fast – with complete spatial image capture 10X faster than most 3D approaches, while delivering up to 250 micron accuracy. It does not require fixturing, additional equipment, special safety precautions, or lighting beyond typical ambient conditions.

 Random – Objects in any orientation or tilt
 Flexible – Rigid/semi-rigid, opaque/clear objects
 Scalable- Off-the-shelf 3D sensors for just right accuracy
 Tested – With major robot manufacturers; 3 sigma reliability
 ROI – Less than 24 months

Random Multi-D Inspection: Parts from 50mm to 1,500mm


• Compare – actual 3D to CAD/specs
• Align – lids, caps, tops, fasteners, subassemblies
• Assess – surface splits, gashes, holes, missing or loose items
• Complex Objects – molded plastics, curved objects, machined parts
• Difficult Objects – clear glass, black rubber, Mylar, celophane-wrapped, stacked metal
• Combine – with Spatial Vision Robotics for vision guidance or Neocortex for automated intelligence for random situations

Inspecting Small Random Parts in 6 degrees of freedom


Traditionally, pallet inspection has been done visually with varying levels of manual handling or automated machinery, requiring the pallet to be lifted and flipped to see all surfaces. Stringent and frequent audits are required to reduce the variability of visual inspection. Traditional 2D vision is not as reliable as 3D due to the limitations of the technology and the structure of a pallet. Replicating manual inspection requires a flexible, automated vision system that quickly identifies a wide range of defects, including raised nails, and wood damage – whether split, loose, or missing – at a productive line speed. Universal’s 3D solution sees more of the pallet at a faster rate than current approaches.

In fact, CHEP, the global leader in pallet and container pooling services, has selected the Universal Robotics Spatial Vision Inspection (SVI) solution for automated 3D pallet inspection worldwide.

Flexible 3D Logistics Inspection: Areas from 1M to 10M


Whether inspecting parts on a table or within a workstation, or identifying boxes at the far end of a truck trailer, Spatial Vision Inspection integrates just the right mix of off-the-self cameras and 3D sensors to enable real-time inspection of your products.

One of the unique capabilities of Spatial Vision Inspection is stitch together up to eight 3D maps (point clouds) from a variety of sensors, and process and analyze the integrated result faster than the physical movement of a machine or robot.

Whether it is inspecting a turbine part at close range, or looking into a 52′ long truck trailer, Spatial Vision Inspection software works with a wide range of sensor types from any vendor. The 3D accuracy and size of field of view are key parameters of sensor choice.

Universal Robotics experts collaborated with Nvidia engineers to optimized flexible parallel processing to ensure massive data sets with sophisticated algorithms deliver real-time results.
