• VISUALISATIONFor adding graphics on the image, visualising the operation of the toolAll or this tool only visualisation, can be selected

• RESULTDisplaying all the results from the operation of the tool

16

Image used for scaling

• In the catalogue Scaling there is an image with millimetre indicators

• Go to ”Camera” and select the correct directory “Scaling” under Image Setting

17

Scaling image on the screen

18

Manual measurement on the image

• When the mouse is positioned over the image right click to get the menu

• Select ”Show info” and then ”Measure”

• Measurements can now be done from the pixel origo point (0 ,0)

19

Measure distance in pixels

• The distance is measured in pixels

• To set a new origo position the mouse directly on the new origo (use zoom if necessary)

• Then right click to get the menu and select ”Set origo”

• TASK: Measure how many pixels there are in 50 millimetres

20

Configuration of ScaleReference

• If the number of pixels are 480, then we can calculate the parameter to be entered for X and Y

• 480 pixels/50 mm= 9.6

• Look at the result from the tool – it is the pixel resolution of the image(1 pixel = 0.10 mm)

21

Visualisation and scaling

22

Saving and storing

• Saving configuration– Pressing Profile button

– Each time you press the Start button

– Each time you close the application

• Archiving a profile– Select ”Maintenance”

– Press ”Backup” button and follow instructions

23

Changing back to image catalogue

• Select ”Camera” and set the image catalogue back to ”Images”

• Press ”Snapshot” to verify that you get the correct images

24

Start and Stop of Inspections

• Automatic inspection• Pressing ”Start” button set

Scorpion in Running mode

• For every new image an inspection is automatically executed

• The image can either be triggered from an external system or from an internal scheduler

• Pressing the ”Stop” button stop the process

• Manual inspection– Pressing ”Snapshot” button grab a

new picture

– Pressing ”Inspection” button execute the inspection

– Pressing ”Snapshot” button again will grab another new picture.

25

Scheduler

• For setting up tasks running at scheduled intervals

• The task ”Trigger” is configured to grab an image every 1000 ms

• When ”Start” button is pressed a new image is grabbed every 1000 ms

• By pressing edit you can adjust the time interval

26

Using a Blob to locate the object

• Add a new tool in the toolbox:

– Name= FindObject

– Tool = BlobTool

27

Using Reference in a tool

• Select Scaling as parameter in the Reference box and click on ”Apply”

• Show info on the image

• mm coordinates are now used in this tool

28

ROI – Region of Interest

• Each tool can must be configure to search in a specific area on the image (Range of Interest – ROI)

• Move the mouse to the centre of the image and read the X and Y coordinates.

• Enter the co-ordinates and specify the delta X and delta Y values

• The ROI visualisation is shown on the picture

29

Understanding the Blob tool

• A blob search for areas in the specified ROI with greyscale values within a given range

• Place the mouse on the object and read the greyscale value

• If the maximum Threshold is set to higher value and the minimum to a lower, the Blob tool will find the object

30

Apply your configuration

• To apply a new parameter set by you, the button apply must be pushed

• You can also set minimum an/or maximum requirements to the blob area to be located

31

Blob visualisation

• Through the visualisation you can see how the tool works on the image

• Activate only CenterofGravity, MaxContour and ROI

• Remember to push ”Apply” before you see the result!

32

Blob result

• Check the result of the blob tool. Here you can find the number of blobs, individual blob areas and ”Holes”

33

Holes in a Blob

• A Hole is an area inside a blob with greyscale values outside the max and min values set in the blob tool

34

Application of using holes

• Counting the dice

35

Avoiding false alarms

• In a real control system situations may occur where the system will not recognise an object or cannot do the configured measurement.

• Consequently, a vision control system should be prepared and configured for such situations in order to operate properly

• In our example we know that it may occur that no object is present

• Therefore we want to establish a logical classification of Object Present

36

ObjectPresent – logical classification

• To establish a logical classification we use the Logic Tool

• Push ”New” and name it ”ObjectPresent” and select ”LogicTool”

37

Configuring a Logic Tool

• We can use the size of the blob area as the classification parameter

• Push Edit and select the ”FindObject” tool and select the blob(0) area

• Click OK and Apply, you will now see the value of the actual blob area

• Click Edit again and set the minimum area to i.e. 100

38

Checking the ObjectPresent tool

• Select the result panel and go through all images and check that the result is correct

• Object present should give Value = 1

• Object absent should give Value = 0

39

Configuring the User Interface

• In Settings mode we can define the Logical States the system shall communicate to the user and to the process control system

• The valid logical state after an inspection is displayed in the Result Panel

40

OK condition - Object Present

• Double click on the existing OK state

• Now you can enter a new name, description and select the colour for display in the result panel

41

Defining the OK (Present) condition

• Click on ”Constrains” and ”New”

• The box shows a list of all available logical classifications in the Toolbox

• Select ”ObjectPresent”• The OK condition is now

true when the logical classification ”ObjectPresent” is true (=1)

42

Testing the OK condition

• Run through all pictures and check the result of the condition (true or false) and the display on the result panel

• When no object occur the result panel display ”Undefined Condition” since no condition for NoObject is yet defined

43

Adding a NoObject Condition

• Click on ”New” for adding a new condition

• Name it ”NoObject”• Select Red as

background colour (when this condition is true the result panel will be red)

44

Configuring the NoObject condition

• To define the NoObject condition we can use ObjectPresent Logical classification

• Click on ”New” and select ”ObjectPresent”

• To make the NoObject condition true when the logical classification ObjectPresent is false, we invert the statement by pushing the invert button

45

Testing NoObject State

• Run through the pictures and check:– the result of the both

conditions (true or false)

– The colour and text in the result panel

46

History list

• In the Operation Mode you will find the History list

• The history list contain the picture an all result from the inspection

• You can configure the list by right clicking the mouse

47

Statistics

• In Statistics you find the result of current period and previous period.

• The statistics use the logical conditions

• By right clicking the mouse the statistics can be configured

48

Scorpion Events

• All processing in Scorpion are managed through ”Events”

• For each Event one or more commands will be executed

• New Events and Commands can be configured by the user

• A more detailed description of Events are found in part 2

49

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

50

Adding a RS232 command

• In command sequence for Inspection click on ”New”

• Select ”RS232Cmd”

• Name the command ”SendStatus”

51

The command protocol• Syntax

”Text” %dparameter– Text = user defined text– %d = format instruction for

the result value (1 digit)– Parameter = The parameter

description of the result from any of the tools in the toolbox

• To find the parameter description of the result push the ”Parameters” button on the top toolbar

• Select ObjectPresent and Value and click on the copy button

52

Writing the command protocol

• Open the SendStatus command

• In the Parameter field write the following– Status=%d

• Place the cursor after the d and paste (right click the mouse)

• Status=%dObjectPresent.Value

53

Testing the communication

• Mark the SendStatus command

• Push the Execute button – Now the command is run once

• In ”Communication” select RS232 - here the out messages are logged

• Check that the correct status value is sent

54

Testing the Scorpion Profile

• Activate automatic inspection (push Start) and check that the status value sent over RS232 is correct for each inspection
