405-00026-00 iNspect Express User’s Manual The iNspect Application Creating an Inspection Solution 1. Launch iNspect Client You need a PC that is connected to the BOA, either through a local network or by directly connecting through a crossover Ethernet cable. If you have not configured the PC and BOA to communicate please refer to the BOA Installation Manual for instructions on changing the IP Addresses to be compatible.
iNspect Express User’s Manual 405-00026-00 Introducing the iNspect GUI The interface has three panes or panels. The left panel is for Control and Navigation, with the Action Buttons. The right panel is the Work Area, and displays the camera image. The bottom pane is for Configuration and Status. These panels are always present in the application window, but most of the following figures show only one panel.
405-00026-00 iNspect Express User’s Manual If the BOA is currently running and inspecting, the application will open to the Run panel, pictured on page 94. Click the “Ok” button to return to the main panel shown on the previous page. 2. Start Creating a Solution a. Click on the “Select Solution” button, in the Control and Navigation panel. The Configuration and Status panel shows new controls for selecting an existing Solution file, or starting a new Solution. b.
iNspect Express User’s Manual 405-00026-00 3. Set up the Sensor In the “Setup or Modify” area on the Navigation panel, only the Sensor button is active (after “Start New Solution”. This step must be completed before any of the other Setup buttons can be accessed. If you had loaded a previously saved Solution, all of the buttons would be active. a. Click on the “Sensor” button to access the Setup Sensor panel. The Control and Navigation panel changes to show the Sensor Setup panel.

White Balance allows you to “color correct” the camera for changes in lighting or camera sensor temperature. Click the “Set White Balance” button, and draw a rectangle on a white area in the image. You should use an area that is colored white.
iNspect Express User’s Manual 405-00026-00 Displaying Edges and Improving the Image Many tools depend on finding edges in the image. It may be useful to display the edges as a check on the quality of lighting and exposure. The edges cannot be displayed in the Setup Sensor panel because the image is “live”. You must go to the Setup Tools panel. a. Click “Ok” to return to the main panel. b. Click “Tools” to go to the Setup Tools panel. c. Click “Take a Picture” or “Snap Triggered” to take a still picture.
405-00026-00 iNspect Express User’s Manual Using the Calibration Tool Calibration is an option, not a requirement. Calibration corrects for field distortion or perspective, and changes the units reported. If you wish to only change units, you can use the Scale button in any length or distance measurement. If you do not use calibration or scale, measurements are reported in pixels. If you perform calibration or scale, measurements are reported in real units: cm, mm, or inches.
iNspect Express User’s Manual 405-00026-00 4. Set up Measurements a. In the main panel, click on the “Tools” button. Setting up an inspection involves the following steps: 1. Define a template image (reference image of the part to be inspected). 2. Train the Color Map if you are using a color sensor. 3. Apply vision tools and set up associated pass/fail tolerances. 4. Add a Locator if the part moves within the image area. 5. Exit this panel and set up communications.
405-00026-00 iNspect Express User’s Manual Define a Template Image Make sure a good (or perfect) part or assembly is in front of the camera, in the location where your inspection parts will appear; or a series of good parts moving past the camera. b. Click on the “Take a picture” button (top left) to acquire a reference or template image. If using an external trigger click “Snap Triggered”. You will use this Template image to set up your measurements and tolerances.
iNspect Express User’s Manual 405-00026-00 Train the Color Map a. Click on the “Setup Color” button. The Configuration and Status panel allows you to define colors or teach “color classes“. Color classes represent “segmented colors“ in the image, on which some iNspect tools can be applied. The default (New Solution) list of “Classes“ has just the “Background” color. By default, all untrained color shades will fall into the “Background“ class.
405-00026-00 iNspect Express User’s Manual To add more color names 1) Click the “plus” button (+). Type a color name in the text field. 2) Click on the green “check” button, to add this name to the list.

iNspect Express User’s Manual 405-00026-00 Performance Tips Your BOA Vision System is optimized for performance, but for very high-speed applications, it may be necessary to minimize inspection overheads, to prevent “part skipping”. This can happen if the inspection queue is full when a new part to inspect is detected. In most cases, this would not be a problem given that the BOA Vision System can capture new images as it processes and renders a result on a previous image.

iNspect Express User’s Manual 405-00026-00 LOCATOR EXAMPLES Creating a Locator requires one or two tools that create active points. While there are several tools that can create active points, some do not make good choices for the Locator anchors. Match Tool The Match tool is a great choice, because it has a search box. You can adjust the search area to compensate for movement of the part. You can change the Match tool properties to look for edges only or all pixel intensities.
405-00026-00 NOTE iNspect Express User’s Manual The Position anchor alone can track or follow horizontal and vertical movement, but not rotation. If your part is mechanically restricted to not rotate, for example a square or rectangle part sliding between two closely fitting rails, the position anchor alone may be enough. If your part does rotate, you need a Rotation anchor too. 7. In the Configuration and Status panel, select Rotation anchor. Click on the center point of the second Match tool (MS2).
iNspect Express User’s Manual 405-00026-00 Pencil Line Intersection Some parts may not have features that are good for the Match tool. If the part has straight sides, the Pencil line may be a good choice. 1. Click the Pencil tool. In the image area, create a pencil line on the edge or side of the part. 2. Create a second pencil line on another edge. The illustration shows the 2 lines, and the four click points.
405-00026-00 iNspect Express User’s Manual 3. Hover your cursor over the first line. Drag the square handle at the end of the line, to extend the first pencil line past the end of the part. Extending the Pencil Line 4. Hover your cursor over the second line. Drag the square handle at the end of the line, to extend the second pencil line past the end of the part, to intersect with the first pencil line. An active point is created where the two lines meet (intersect).
iNspect Express User’s Manual 405-00026-00 6. Hover over the third click point (second line), and extend the size of the search area to compensate for movement of the part. Repeat for the second click point on this line. Increasing the Search Area 7. Click on the Locator button. In the Configuration and Status panel, click on Position Anchor. 8. In the image area, click on the intersection of the two pencil lines.
405-00026-00 iNspect Express User’s Manual Edge Count Tool – Circle In some cases the Edge Count tool, used with a Rectangle or Circle ROI may be a good locator for parts that rotate by large amounts. The Match tool does have settings for rotation, but also takes more time for accurate tracking of large rotation. For this example, the notched disk in the following figure is always placed on a (non–moving) shaft in the camera view. The only movement is rotation.
iNspect Express User’s Manual 405-00026-00 8. In the Configuration and Status panel, select “Rotation anchor” 9. Click on the point at the left edge of the notch. The flag icon should appear. Loc1 Notched Disk with Locator Anchors We need two anchors to find the rotation. The circle tool works only because the center of the disk is always in a fixed position in the image area.
405-00026-00 iNspect Express User’s Manual 5. Click on one of the points on the Edge Count region. A cross hair appears with a label “Loc1”. 6. In the Configuration and Status panel, select “Rotation anchor” 7. Click on a second point on the Edge Count region, the furthest point from the position anchor is best. The flag icon should appear.
iNspect Express User’s Manual 405-00026-00 4. Click on the Locator button. In the Configuration and Status panel, select Locator 1, and select “Set position anchor”. 5. Click on the Center point of the Match Tool. 6. Select the Edge Count tool and select a Circle Region. 7. Draw a circle on the disk, near the outer edge and passing through the notch. Move and resize the circle as needed. Loc1 Locator 1 and Edge Count Tool 8. Right-click on the Edge Count tool, to open the Properties.
405-00026-00 iNspect Express User’s Manual EQUATION EXAMPLES Override Examples Here are examples for setting override variables in the “Post Image Process” function. The composite result is formed after all statements have been evaluated. NOTE The variable FAIL supercedes RECYCLE and RECYCLE supercedes PASS. The variable Result (the Composite Result) takes 3 values: 1, 2, 3 where 1=Pass, 2=Recycle, 3=Reject. Example 1 FAIL = 1 RECYCLE = 1 PASS = 1 The Composite Result = 3 which is the value for Reject.
iNspect Express User’s Manual 405-00026-00 Output Examples Indicate a Pass or Fail You can make the outputs indicate the inspection passed or failed. This very similar to selecting ”Pass Pulse” or ”Fail Pulse” in the ”Setup I/O Connections – Outputs”. You can specify your own pulse width using scripting. This example is a shows a long pulse width. If (Result.0 = 1) Global.GPO(0) = pulse(1,3,400) If (Result.0 = 3) Global.
405-00026-00 iNspect Express User’s Manual If () Global.GPO(1) = (MS1.Result != 1) Set GPO(1) to logic 1 if MS1 match does not pass; set GPO(1) to logic 0 if MS1 match passes. “If ()” is the first of 3 fields in the statement. It gets dropped off in the Manage Equation Execution Order panel. , and the statement becomes: Global.GPO(1) = (MS1.Result !=1) MS1.Result is the Pass/Recycle/Fail result of the Match tool. MS1 is the measured value of the match.
iNspect Express User’s Manual 405-00026-00 In the Delayed Event Function, set the outputs low. Delayed Event – 60 ms after Image Process: If () Global.GPO(1) = 0 If() Global.GPO(0) = 0 The Delayed Event Function can also be used to clear or reset PLC registers or other external devices. Related Functions You can use the Solution Initialize Function to clear or set outputs and PLC registers when you load a solution.
405-00026-00 iNspect Express User’s Manual Input Examples Using a Control Logix Tag for a Trigger Vision Systems can use a Control Logix Tag for an inspection trigger. Because the Vision System is interfacing with external equipment, there are several steps to prepare or verify the setup before the assignment equations. 1. Set the Sensor Trigger to Inspection Trigger, in the Setup Sensor panel. 2. Add the Control Logix PLC to the Solution file.
iNspect Express User’s Manual 405-00026-00 5. Set the time interval (30 ms) for the Periodic function and then click the “Add” button. The Periodic Function now appears in the Function list. The Periodic Function will occur at the interval entered (30 ms). To prevent multiple inspections per trigger a variable called “Once”, in this example, is set after one trigger is generated and will be reset after the image is processed.
405-00026-00 iNspect Express User’s Manual A tag that indicates that a trigger has been received is written to in the Pre Image Process function. This function is executed one time prior to the image processing of the image just acquired. After the PLC receives this indication, the PLC should change the state of the trigger tag to avoid processing the same part after image processing is complete.
iNspect Express User’s Manual 405-00026-00 After the inspection is processed, the “Post Image Process” function is executed one time. This function should output the inspection results to the appropriate Control Logix tag(s). The variable, “Once” in this example, that keeps the Periodic Function trigger from happening multiple times should be reset. The arrows to the right, between the Edit and Del buttons, are used to put the statements in the correct order.
405-00026-00 iNspect Express User’s Manual GLOSSARY Accuracy – For most measurement tools, increasing the “accuracy” means increasing the number of sample points. Refer to the detailed description of each measurement tool. Binarization – turning a gray-scale image into a “binary image” with all pixels replaced with values 1 and 0. Camera – The camera contains a sensor that converts the pattern of light from the part into electrical signals that are sent to the Vision Appliance.
iNspect Express User’s Manual 405-00026-00 Lighting – In most cases you will need special lighting that ‘amplifies’ the elements of the part that you want to inspect and ‘attenuates’ elements that you don’t want to inspect. Proper lighting makes inspection faster and more accurate. Poor or inappropriate lighting is a major cause of failure in machine vision inspection systems. Light Ring – a ring or circle of Light Emitting Diodes or other light sources in a circle.
