Video – Scorpion Retro Robot Vision

This promotional video was created more than ten years ago – it is still fun to watch.

It is uploaded as reference of the first Scorpion 2D Robot Vision applications deployed from 2000 to 2002. These applications have been running in many years and some of the application are still alive and some have been retrofitted to increase the flexibility and performance.

We can still support all these systems with our 100% backward compatible software. 

Video – Tool Threading and Template Classes make Scorpion Vision fly

This video shows how template classes and tool threading speeds up Scorpion image processing proportional to the number of cpu-core on the computer. The demo requires the latest Scorpion Vision version X.II.

The task of measuring 24 spouts of the bottles in a crate is configured in less than 5 minutes – for every bottle a thread is created automatically ensuring completely parallell image processing without any programming – Watch for yourselves.

Watch Bob Hindcliff, Quasar Automation and Jeremy Shinton, Mitsubishi Electric discuss the unique food safe robots from Mitsubishi.

The focus in the discuss is how these are used in the award-winning solution from Quasar Automation to provide automatic 3D deposit solutions for the food industry.

The solution is powered by the Scorpion 3D Stinger MLaser Camera – read more – the video contains a nice description of how to apply  the Scorpion 3D Stinger MLaser Camera.

New in Scorpion Vision X.II – The best circlefinder in the world?

One of the fundamental challenges in Machine Vision is to locate round objects.  In Scorpion Vision X.II we are proud to announce a new significant tool – CircleFinder2D.

Ten years of knowledge and practical experience is built into CircleFinder2D

More than ten years after releasing RadialArcFinder a ransac based circlefinder with subpixel accuracy we have been working hard to create a new tool that meets the challenges our Scorpion 3D Stinger technology. The challenge is when we doubling the accuracy of a feature in 2D we also double the 3D depth resolution. With CircleFinder2D we have seen 2-4 times the accuracy in depth resolution in challenging 3D picking Robot Vision applications by just replacing RadialArcFinder by CircleFinder2D. This means that we can solve more application or lower the cost of existing solutions.

Robust Bottle Center Location using Ellipse option of CircleFinder2D

Robust bottle center estimate using the dual pass and ellipse option of CircleFinder2D. The bottle is view with a 30 degree perpective or angle.

Last year we added the the Scorpion Tool Components – STC-0046 FindCircles that was based on Detect/Fitting Circles using Hough Transform in OpenCV and the STC-0039 EllipseFit that fits an ellipse from a collections of 2D points. These activities increased our understanding of circle finding and that we could create a CircleFinder2D that is significantly better than these implementations.

A selection of features in CircleFinder2D

  • Works with Color Images – Low contrast detection in color images

The CircleFinder2D locate low contrast bottle, low resolution in color images captured with wide angle web cameras. By clever algorithms an ellipse is fitted using the valid ellipse edge points.

Locate Bottle in Color Image with CircleFinder2D

Locate a bottle in a color image with CircleFinder2D – speed is 11 ms – the resolution and contrast is low and difficult

  • New – Clever user defined cost function

The user defined cost function lest the user define the criteria for selection the “best” circle located by the ransac algorithm

New cost-function lets user specify optimal search to locate circle

New cost-function lets user specify optimal search to locate circle

  • New – User define ransac iteration through Multi-Search Function

A challenge with ransac based tools is to generate independant samples to be able to find the best solution. With the user defined MultiSearch multiple search for edge points can be be specified.  More of less all the parameters of the CircleFinder2D can be iterated: origin, fitted points, traceline width, steps and search count. When a solution is found with acceptable cost function the search can be terminated to optimize the system solution speed.

  • Accurate – Dual Pass doubles accuracy be two step edge location
  • Accurate – locates circles based on sub-.pixel edge detection
  • Robust – Extensive set of contraints to improve ransac point / solution selection
  • Perspective – EllipseFit fits circles with perspective properly
  • Flexible – Option to set minimuym number of points to %
  • Fast – Multiple CircleFinder2D can be processed in parallel using the Scorpion Tool Threading
  • All the search results are available for investigation to understand the circle fitting process.
  • Advanced – The results can be used for validation and verification in 3D space increasing the accuracy and robustness of a Scorpion 3D Stinger system.


The tool is created to solve the true challenges of location of round objects in 2D and 3D machine vision. The tool are significantly increasing the robustness and accuracy of our Scorpion 3D Stinger based solutions with respect to automated 3D calibration and feature location.
