• Scorpion Design

• Scorpion Methodology(How to make a Scorpion Vision system)

• Scorpion Product Overview


Design criteria• Complete Vision System • Standard Components• Low component cost• Powerful• DIY - Do it Yourself!

The easiest way to implement and maintain an advanced vision system


Low Component Cost

• Use standard/commodity hardware• Standard PC with Windows 2000/XP• Complete support for USB and FireWire Imaging

(standard PC ports) through Microsoft standard DirectX

• Standard communication links• RS232, TCP/IP included in the PC• I/O using Adamtech modules (RS232 or TCP/IP)• dB access with ODBC


USB and FireWire Imaging

Complying with Microsoft WDMand DirectX/Show specificationable you to acquire images from

any WDM based imaging hardware,and the transfer of images is

100% standardised


USB and FireWire Cameras• Benefit from the

multimedia revolution• No proprietary hardware

like Framegrabbers and Vision Sensors

• Connect one or several cameras directly to one PC

• Select a camera suitable for your application(Low Cost or/and High Quality)

From 100 €

To 650 – 8.000 €

Baumer


Powerful & Flexible

• Benefits from the ever increasing power of Intel processors

• Multiple camera connections direct to PC through FireWire/USB imaging

• Fully featured robust and reliable image processing in Scorpion Toolbox

• Flexible - upgrade for more functionality, more cameras, more resolution or processing power


Scorpion for custom vision systems

• Interface with plug-ins; dynamic link libraries (DLLs) and Active-X

• Unique python scripting capability to solve special needs


DIY - Do it Yourself!

• Designed for production engineers that want to develop or maintain their own systems and be independent of expensive system integrators

• Easy to use non programming user interface

Methodology• Connect the image input(s)• Define the Logical States

(events that may occur in the Production Process)• Define inspection criteria• Vision strategy and configuration of vision tools• Establish basic states needed for the Logical States• Configure the Communication links to external

systems• Configure the user interface


Starting point• Operation mode: (No password)

– For operators– Can start and stop the inspection– Read history list, curves and

statistics– No access to any configuration

• Settings mode: (Password: 1234)– For operators certified to adjust

logical states and alarm limits• Service mode: (Password: 911)

– Full access to all functions– Camera, vision tools,

communication set-up


Connecting Image Sources• Camera connections are

handled by Windows (plug and play)

• Cameras recognised by Windows are automatically available in Scorpion

• Note: Can also connect to IP Video Servers and other Cameras


One camera – several images


Several cameras


Colour with HSI conversion



(events that may occur in the production process)• Define inspection criteria• Vision strategy and configuration of vision tools• Establish basic states needed for the Logical States• Configure the Communication links to external



Define events that may occur

• Inspection:– Inspection Passed– Inspection Failed– No object present– Cannot measure and

inspect– Undefined object– Type XX object

identified

• Robot Vision– Picking point located– Cannot measure

rotation– No object present– Undefined object– Type XX object

identified


States

• These production events are in Scorpion called: “States”

• The States are created and defined in the “Settings” mode


Example of States


Communicating the results

• The name of the State is displayed in the Inspection Result Panel

• Text and colour is user defined


Defining the constrains• One or more logical

conditions can be used• A logical condition is

either true (value=1) or false (value=0)

• The logical conditions are set in the tool box based on testing results from any vision tool against user defined conditions(distance, area, radius)


Define related commands• Depending on

inspection result (States), one or more commands can be executed:– Sending status info to

PLC or Robot– Sending data to PLC or

Robot or a database– Save images


Inspection criteria

• A logical test of one or more measured parameters generated by the vision system

• Used to define the Logical States equivalent to the events that may occur in the production line


Defining Inspection criteria• Select inspection parameters:

– Measurements of area, dimensions (line, distance, radius)

– Read or verify text or code– Verify a colour or greyscale surface– Find or verify position and rotation– Counting number of areas, lines, circles

• Set inspection tolerances:– Acceptable +/- values for each inspection parameter


Example of inspection criteria

• Logical States– Object Present

– Type of object

– Inspection Passed

– Cannot measure

• Parameters– Area of object within

certain limits– Size of object

– Radius within tolerances

– Quality of circle too low


Vision strategy

• How to locate the object?• How to handle rotation?• How to handle illumination variations?• How to identify a specific object?• How to measure the specific parameters

needed as inspection criteria?


The Scorpion Toolbox• Blob tools• Edge/Line finder tools• Logic/Data tools• Reference tools• Geometry tools• TemplateFinder tools• Barcode &MatrixCode• PolygonMatch tool• Color Matcher tool• Image Processing tools• Python Script Tool


Vision Strategy example

• How to handle rotation?• How to handle illumination variations?• How to measure the label position?


Vision strategy example


Implementing inspection criteria

• Testing measurement results against limits using Logic Tools


Communication with external systems

• RS-232– Raw, tdvcmdprotocol

• TCP/IP– Raw sockets, tdvcmdprotocol

• I/O using ADAM modules from Advantech(RS232 or TCP/IP interface to computer)

• Profibus • OPC• Database ODBC


Scorpion Actions• The Scorpion

Command centre• Set the operational

sequence– Image acquisition– Inspection

(running the tools)– External

communicationIn and Out)


Actions = Power and Flexibility

• Easy communication using names (“camera trigger”)

• Flexible image grab sequence (multi camera or multi position using a robot)

• Robot Vision (signal move robot after image grab but before inspection is finished)

• User defined events– Communicate product type

Sending Status data to a PLS• We want to send status data

(object present or absent) using the RS232 interface

• We will link the timing of sending the data to the event ”Inspection”

• Initially the event inspection activate the command ”Inspect”.

• After that we want the system to send status data


Testing the communication• Add a new RS 232

command• Select the parameters to

be sent (All parameters from all tools are available)

• In ”Communication” tab you can monitor both outbound and inbound messages


Configure the user interface

• Result panel

• Indicator panel

• History list
