Is the box Empty? – A perfect solution using the Scorpion 3D Stinger MLaser Camera

Introduction

I have been working with Robot Vision for more than ten years. In the beginning we were happy when the could pick at all and the robot did not crash too often :) When picking from boxes and pallets the there is always a last challenge to know that the layer or box is empty before you move it away – if you are wrong it hits hard when the robot moves non-empty box.

Scorpion 3D Stinger Starter KitScorpion 3D Stinger MLaser Camera

Our innovative and new solution is the Scorpion 3D Stinger MLaser Camera. The system consists of the following standard elements:

  • Scorpion Vision 3D Empty App
  • Compact PC running Scorpion Version X
  • Scorpion 3D Stinger MLaser Camera

The Scorpion 3D Stinger MLaser Camera is a combined with a 10 mW or 100 mW multiline laser that is projected onto the pallet or into the box.

Locate moving objects in 3D

The technology is not limited to robotics – the challenge also exists in all kind of box moving application where everything stops when the box or conveyor is not empty.

Scorpion 3D Stinger MLaser is able to operate with superior performance based on the following features:

  • Packaged in the Scorpion 3D Stinger Camera
    • Using stereo vision to locate the laserlines
  • Automatic and Accurate One Push 3D Calibration
  • Robust sub-pixel 2D location of laser lines

The image shows an plane surface illuminated with 15 laser lines – the surface does not reflect the red laser very well

Locate laserlines FindPaths2D

The laser traces / paths are located with the Scorpion Tool Component FindPaths2D even with low contrast. Note that the outermost laserlines are not straight

  • Create a 3D Image in Real-time 
    • The Scorpion Tool Components LocatePaths3D has significant features to handle missing laser points and folding challenges.
    • The sample shows a point cloud of 4489 points that is generated in 165 ms
Empty_3DImage

The most accurate 3D image is created – the rms value for the 4889 3D points is 0.29 mm – given a 2D pixel resolution of 0.62 mm

The Scorpion 3D Stinger MLaser Camera is created to solve demanding applications in robotics and automation. It has a long list of features that make a difference in mission-crtitical applications. The 3D technology is available to OEMs and System Integrators.

Used to solve challenging 3D Bin Picking

YouTube ButtonWe have used the Scorpion 3D Stinger MLaser Camera to solve an innovative 3D Bin Picking solution for dog food packaging using an ABB robot.

With a fast vision cycle time of less  than 500 ms a robust strategy must be developed. The empty check is critical for 100% reliable operation because the robot must empty the bin before moving the box away.

The animation shows the the two stereo-vision cameras, the 3D Model and the corresponding height map. There are images showing one item, two items and empty.

Scorpion 3D Stinger for Robot Vision

Scorpion 3D Stinger for Robot Vision

Together with our excellent automation partner Dynatec from Askim, Norway we have developed an innovative 3D Bin Picking solution for dog food packaging using an ABB robot.

The cycle time of the system is less than 2 seconds leaving less than a 500 ms for 2D and 3D image processing. This requirement called for an innovative approach using the new Scorpion 3D Stinger Camera that locates moving objects in real-time in 3D.

The video shows the 3D Bin Picking solution in operation picking the smallest sausage. The system handles three different sausage sizes.

The pace is fast – the sausage is rolling and moving while picking – the system handles this with ease.

Scorpion 3D Stinger for Robot Vision

We designed a solution based on our latest 3D technology and Scorpion Vision Software Version X. The Scorpion 3D Stinger for Robot Vision was implemented using a Scorpion Industrial PC and a Scorpion 3D Stinger MLaser Camera.

This solution adds the speed and accuracy by extracting 3D data from 2D images in addition to using structured light. This creates contrast on the sausages making it possible to use a 3D Cylinder fit to locate the dog food with the required robustness.

3D Cylinder Model

Each dog sausage is located based on structured light and a fast and reliable 3D Cylinder Fit

The system is very fast and reliable due to the unique Scorpion 3D Stinger concept  ”Extracting 3D from 2D images”. The 3D technology is proven and is ready to be used in applications in many industries.

CATS – Characters Acceptance Technology Software

We are proud to present one of our many OEM-partners  VPTS from Gillingham in UK. They have over the last three years created a very good CATS solution.

Leon Stonebank of VPTS says “Most camera systems have old outdated technology. We use the latest versions of drivers, hardware and software. The CATS system is based on Scorpion Vision Software, an industrial automation package that is used widely throughout industry in many sectors including automotive, food and beverage, oil and gas, general manufacturing and aerospace.

Scorpion Vision is a mature and well developed machine vision product that offers the robustness and reliability that ensures CATS operates 24 hours per day 7 days a week.

We integrate an easy to use interface between the Scorpion Software running in the background and the user.

Over the years we have been involved with many different types of vision systems and know the limitations and costs involved.  

Which leads us to our system : Developed over 3 years and from looking at all the possible suppliers and vision systems available. We think we have the best combination of hardware and software. Scorpion Vision Software, Unibrain Cameras, Omron PLCs and Controls.”

The core Character Acceptance technology is based on the Scorpion Vision TemplateFinder3 tool. The system verifies text, 1D and 2D barcodes with up to 16 Unibrain cameras.

Customer Reference

kpm’s requirements for a camera solution were very specific. Above all it needed to be both quick and easy to setup by operators, have the ability to read accurately from a vast array of lasered or ink jetted substrates and font sizes. The system supplied by VPTS has definitely proved itself over the last three years and the support from them has been excellent. As a result of this success VPTS installed a second system towards the end of 2012.”

Version X supports OpenCV 2.4.3

Scorpion Vision Version X supports OpenCV 2.4.3 which was released the 2nd of November. We plan to follow OpenCV, Numpy and Scipy because these libraries are important to anyone. We want Scorpion Vision to be the best way to integrate these libraries through Python. We are are a proud user of Python since 2001 when we included it in Scorpion Vision version 2.0.

In the Scorpion Vision Software Version X build 533 we have added a nice profile that shows how we can access all the samples and the most of the OpenCV code directly from python and Scorpion Vision. Below a screenshot using Windows-8 :) and Scorpion Version X.

The OpenCV samples are accessible with a mouse click

Below the kmeans clustering is shown.

Turn any PC into a machine vision system

With the release of Version X the new Metro look and Windows compatibility we are happy to announce that Scorpion Vision Apps 2.0 is available for our customers and partners. The compact user interface is a great value when working with PC with multiple machine vision systems.

“The Scorpion Vision Apps turn any PC with a camera

into a professional Vision System”

We have updated all Vision Apps to 2.0 and they will be at display at Vision-2012 in Stuttgart next week.

Dirty Filtering with Version X

Inspired by the film “Dirty Dancing” – this image shows what you can do with image filtering even when there is NO contrast :) and you need to find an object.

How can we do it? Try Scorpion and STC-0011-OpenCVFilter and learn the dirty filtering…
