Making it Easy – STC-0028-PointExtrema

Posted on May 28, 2012 by Thor

With Scorpion Tool Components we strive to make it easy. The STC-0028-PointExtrema calculates the extremal point based on three or more points. This is needed to perform sub-pixel width measurement in the sample below.

The challenge:  To locate the outer-most points – to measure the maximum width – a good way to do this is to estimate it from a sequence of edgepoints

How we solve to locate the outer-most points:

  1. Locate the six objects with TemplateFinder3
  2. Locate edge points with SingleLineFinder
  3. Use STC-0028-PointExtrema to estimate the outer-most point with an 2 or 3th order polynom

2. EdgePoints located with SingleLineFinder

3. The estimated PointExtrema – fitted with 3th order

STC-0028-PointExtrema Setup

It is just to link to the SingleLineFinder output polygon and the PointExtrema is estimated accurately.

Making it Easy – STC-0025 PolygonExtrema

Posted on May 26, 2012 by Thor

With Scorpion Tool Components we strive to make useful things easy. The STC-0025 PolygonExtrema is such an operation. Find the extremal points from a polygon.

Find the extremal points of a blob contour

To use STC-0025 is easy – it is a Scorpion Tool Component

STC-0025 PolygonExtrema is easy to use – just link to a polygon

It will be available will Scorpion Vision 9.3 :)

Scorpion Vision in R&D – Syringe Fill Level Measurement

Posted on May 20, 2012 by Thor
This is an update on the development work being done by Denis Lebel of Sainte-Justine Hospital in Montreal based on Scorpion Premium 3D.
As you will see at the following YouTube link, the application is to read the fill level on the syringes… first acting like an error proof double check to the pharmacy’s technician’s (preparing syringes for use in the hospital and in oncology) and second to get an even more precision reading on the syringe’s dosage.

Reading Syringe Volume

Precision’s are excellent at sub-milli-liter reading !  
In the case of oncology drugs, cancer fighting drugs, precise measurements are extremely important since a slight over-dosage can kill the patient instead of helping the patient !  There have been reports of patients being over-dosaged by a factor of 10X and dying !!
The syringe bodies are covered to hide the syringe tip and the measurement is done by reading the piston’s outward distance from the finger grip area of the syringe.

Making it Easy – Image Stitching in Scorpion Vision 9.3

Posted on May 18, 2012 by Thor

In the upcoming Scorpion Vision 9.3 – Image Stitching is just defining another image – no scripting or programming required :)

Image Stiching is just configuring the Image Advanced tab

The resulting image – the number is labelled 1, 2 and 3, looks like this:

Three images stiched – perfect for conveyor applications with line or area scan cameras

1000 parts pr minute by HDS Group

Posted on May 9, 2012 by Thor

The machine is so fast that no manufacturer can follow :)  It is demonstrated at Polytec’s booth at the Control Show in Stuttgart and is a impressive setup.

HDS Group measure, classify and sorts with Scorpion Vision 9.2

The standard Scorpion Vision Operating Screen Shows two images and a custom HDS Operating Screen

The internal of the machine consist of two telecentric hw-triggered camera systems, three pneumatic ejectors, led backlight, the parts flowing on a glassring and the inspected parts being process at 10-16 parts / second with a system resolution of 20 microns

Scorpion Vision extends support for Windows-7 64-bit

Posted on May 4, 2012 by Thor

Adapting to Windows-7 and especially 64-bit is quite a process primarily due to driver support but times are slowly changing to the better. With Scorpion 9.2 we can now report the following verified status:

  • Complete firewire support for Windows-7 32 and 64 bit
    • Unibrain’s generic ubCore driver support all firewire camera through Scorpion Firegrab camera driver
    • Allied Vision Firewire camera is extended with low-level register access  and Windows-7 32 and 64 bit support
  • AVT Prosilica GigE driver has been used for a long time with 64 bit
  • Scorpion Vision supports the Advantech Bionic API with complete Windows-7 support which makes all Advantech io-modules available under 32 and 64 bit.
    • The ethernet adam-60xx modules are supported on both 32and 64-bit through standard tcp/ip connectivity
  • Scorpion Vision 9.2 is also running smoothly both on 32 bit and 64 bit Windows
    • The screen shot below shows a very extensive and advanced 3D Robot Inspection system capturing 34 images and doing more than 200 inspections
    • This Scorpion Profile consumes 2.5 GByte memory. It runs very nicely with headroom on Windows-7 64 bit
      • There is still more than 1 GByte free on a system with 4GByte
        • on 32 bit this would be very tight even with a 3GByte switch enabled.

Scorpion 3D Robot Inspection – 2.5 GByte Memory Consumption

Windows-7 64 bit Task Manager 0.8 GByte Free Memory Space

Summary:  

  • It is time to consider Windows-7 64-bit as your operating system platform!
    • If you need more memory for demanding 3D applications this might be a must.
  • Scorpion Vision will continue to support Windows XP, XPembedded, Windows-7 32 and 64 bit for a long time!
  • With Scorpion Vision you can select your platform based on your own requirements.

Note 1:

  • Camera drivers not mentioned will most probably work with 64 bit – check with the specific camera vendor.
  • Basler promises full support for 32 bit and 64 bit with Pylon 2.3

Note 2:

  • To verify stable camera and io
    • drivers are always important independant of operating system
    • they have to be tested and verified to be able to guarantee stable operation
