2D and 3D Robot vision is one of Scorpion’s focus areas. Scorpion gives the robot the ability to see.
Flexible automation means robots, automation and vision working together. This reduces cost and increases the flexibility and possibility to produce several product variants in one production line at the same time – 24 hours a day – with profits. The vision system’s ability to locate and identify objects are critical elements in making these systems.
Scorpion Vision Software has been used in robot vision and inspection systems for many years. Scorpion has a complete toolbox of robust and reliable 2D and 3D image processing tools needed for robot
vision, gauging and assembly verification. Included is high accuracy and subpixel object location with 3DMaMa and PolygonMatch™ technology making it a perfect companion to World Class Image
Components.
Flexible and easy interfacing to standard robots
With Scorpion Vision software it is easy to implement reliable communication with robots from any vendor.
Scorpion is used with robots from ABB, Motoman, Kuka, Fanuc, Kawasaki, Sony and Rexroth Bosch over serial and tcp/ip ports.
PolygonMatch locates any object with sub-pixel resolution
The PolygonMatch Technology locates any object based on multiple user defined polygons robustly with sub-pixel accuracy. TemplateFinder3 is a high performance cross-correlation based pattern matcher powered by PolygonMatch technology handling rotation, perspective and scaling.
Easy to use four to six point 2D Robot Calibration
Scorpion uses a standard four point calibration to enable the system always to work in robot coordinates. Multiple coordinates systems are supported. With five or six points you can evaluate the accuarcy of the calibration.
Combining Nth order lens calibration to improve accuracy
Combining four point calibration with 5th or 6th order lens calibration improves the precision to a sub-pixel level even with a wide angle lens. To the right a typical lens calibration is shown. This feature is important for 3D Stereo Vision systems because the 3D accuracy is directly proportional with 2D resolution. True sub-pixel will increase the height resolution by a factor of 10!
3D camera calibration
Scorpion uses a simple two step 3D camera calibration. This removes the need for multiple 2D calibrations. When finding objects at different heights, the 2D coordinate systems are dynamically generated. This is often was make 3D Stereo Vision a viable solution with Scorpion Vision. Scorpion 8 supports easy to use chessboard calibration.
Firewire or GigE imaging ensures superior image quality
Using the high quality firewire or GigE cameras – the image quality is ensured even when mounting the camera on the robot. The cameras is available in two versions: monochrome and colour both supported by Scorpion Vision. With analog signal transmission, it can be difficult to shield the cable to ensure image quality. Cable lengths up to 100 meters is supported with standard GigE components. We recommend using flexlink cables when mounting the camera on a robot. In complex applications where two or more cameras are needed, these can easily be added at low cost. Both vga, sxga and higher resolution cameras are supported when high resolution and high quality is required.
Wireless 3D robot vision with Network Cameras
Combining Sony or IqEye Networks cameras and Scorpion Vision Software users can make wireless robot vision systems. Scorpion can run multiple 3D robot vision systems on one computer.
PolygonMatch™ locates any object with sub-pixel resolution
Using the unique PolygonMatch™ edge tool Scorpion locates any object based on multiple user defined polygons.
TemplateFinder3 powered with PolygonMatch™ technology locates multiple objects
TemplateFinder3 locates multiple objects with sub-pixel accuracy. It can handle scaling, translation rotation and perspective. Supporting multiple named templates it can easily be configured to handle automatic product changes. With the interactive Polygon Model Wizard optimal models describing an object ensures robust and accurate object location
Scorpion Vision is used for 3D Stereo Vision based Bin Picking
