Operating Rausch ScanCam Within POSM

Setup ScanCam Result Fields.

When performing Single Point Measurement scans of a pipe, POSM can read the results of the scan data and put them into a value dimension field of the observation. The user may choose which value dimension field the data will be
placed into from the Edit Preferences, Inc/Laser Measure/ ScanCam/Kampac window. The Horizontal Deflection, Vertical Deflection, Width and Diameter are all measured, and may be stored, in any of the 9 dimension fields.

The default settings are: Horizontal=3, Vertical=4, Width=5 and Diameter=6.

Once the fields have been selected, the observation labels may be updated from the Observation and Code Editor.
After selecting the template in which the inspections will be performed, click the “Edit Observation Labels” button in the lower right-hand side of the screen. Once entered, the labels will be updated in the software while adding observations and for the generated reports.

The Default settings are: Val Dim 3=Horizontal Def, Val Dim

4=Vertical Def, Val Dim 5=Width and Val Dim 6=Diameter.

Perform Single Point Scan.

• Make sure camera is centered (single point scans).
• After adding an observation to the session, highlight the observation by left-clicking on it. Click on the blue highlighted observation, then select “Add Single ScanCam.”

• After selecting “Add Single ScanCam,” the ScanCam application and Send ScanCam Distance windows will appear.

• Ensure ScanCam is on the Single Measurement tab.
• Click the Start Setup button on the ScanCam application. It is very important to always let commands finish before clicking another button or command on the
camera controller.
• Turn off Lights on the Rausch Camera Controller.
• If the camera doesn’t pan correctly or the lasers do not turn on, restart ScanCam and/or the camera controller.

• Adjust iris up/down to achieve halo.
• Adjust iris down until values no longer accurately measure the radius of the pipe. The pipe radius (1/2 diameter of
the pipe) is located to the right of the message box with the OK button. Move the iris up until the lasers are cleanly displayed on the screen, not too small and not too large with a halo.

• Press OK to start scanning.
• Camera will spin and left laser will turn on and off.
• Click Acquire Data to start recording ScanCam data.
• Ensure data streams into the list box.

• Once the pipe circle shows on screen, close ScanCam to return to POSM. If the pipe is too far off center, raise or lower the camera and repeat the scan again. The software can measure pipes while the camera is not centered.
To achieve the highest accuracy, the camera should be properly centered in the pipe.

• Once the X in the upper right-hand corner of ScanCam has been clicked, POSM will save the image to the observation and the image data to the observation data.
• Turn on the camera lights.

• Return camera to home, then press the “wide” button on the camera controller to bring zoom back until home.

Perform Whole Run Scan.

• Make sure camera is centered.
• The session does not have to be running, but you must start ScanCam from the Tools menu of the main session form. Some municipalities are begging to require that the scan
be recorded. In this case, the session shall stay running
to keep the MPEG encoder running during the scan. Some operators wish to have these scans in their own video
file. To accomplish this, stop the session to review the inspection run, then start the session again before starting ScanCam whole run.
• To open ScanCam for whole run inspection, click on the
Tools menu, then select “ScanCam Whole Run.”

• After selecting “ScanCam Whole Run,” the ScanCam application and send ScanCam distance windows
will appear.

• Ensure ScanCam is on the “Line Measurement” tab.
• Click the Start Setup button on the ScanCam application. It is very important to always let commands finish before clicking another button or command on the camera controller.
• Turn off lights on the Rausch Camera Controller.
• If camera doesn’t pan correctly, or the lasers do not turn on, restart ScanCam and/or the camera controller.
• Adjust iris up/down to achieve halo.

• Adjust iris down until values no longer accurately measure the radius of the pipe. The pipe radius (1/2 diameter of
the pipe) is located to the right of the message box with the OK button. Move the iris up until the lasers are cleanly displayed on the screen, not too small and not too large with a halo.

• Click OK to start Scanning.
• Camera will spin and Left laser will turn on and off.
• Click Acquire Data to start recording ScanCam data.
• Ensure data streams in list box.
• Click OK to start Scanning.
• Camera will spin and Left laser will turn on and off.
• Click Acquire Data to start recording ScanCam data.

• Ensure data streams in list box.

• In the macro, press Drive, ensure it’s on backward, click slow or med.

• The camera will stop at 10 feet.

• Ensure counter on controller was reset after placing the tractor in the pipe.

• Pull back manually to start of pipe.
• Click Stop to finish collecting data.

• Once the Stop button has been clicked, the pipe graph will traverse the pipe data showing its ovality. Once it
has finished, click the X in the upper right-hand corner of
ScanCam to close it.

• Turn on the camera lights.

• Return camera to home, then click the “wide” button on the camera controller to bring zoom back until home.

View 2D Reports.

After completing a run, the user may view the Horizontal Deviation, Vertical Deviation, and Diameter 2D reports. The report may be viewed by clicking on the ScanCam tab in the report editor.

The user may choose to include blue limit bars. If the “No Limits” option is selected, no blue bar will appear on each plot. Choosing 5% or 7.5% will place a blue bar on the plot at
+5% (-7.5%) and -5% (-7.5%).
By checking the “Show Only +/- Percent” box and entering a numeric value into the adjoining text box ,the plot will be zoomed in to only show data between the entered numeric value. In the example above, the plot will show +/- 7 percent of data.
The Maximum Data Value field will limit the maximum deflection data allowed to be plotted. This is useful when the camera is run past the end of a pipe to keep large spikes from going off the chart.
Change Horz and Vert Data By fields were only used for testing purposes and for advanced users in certain types of pipes to modify the output of the Horizontal or Vertical plots. These values should normally be set to 0.
“Filter Diameters > or < Than From Average” allows the user to adjust the maximum diameter plot values displayed. Like the Maximum Data Value for the deviation plots, this filters out data mostly when the camera is run past the end of the pipe.
“Group Diameter Values in Increments of:” allows the user to average diameter values in the pipe size plot. For example, a

POSM Pro // Operating Rausch ScanCam within POSM. // Page 5

value of 1 will average each foot (meter) of the pipe and plot the diameter. This option is useful for plotting a smooth pipe size plot.
The “Auto Center Data” checkbox will move the Horizontal and Vertical data to the average point. This option should only be used in special cases, such as when the data from ScanCam are the correct percentages.
“Show Horz Plot” will turn the horizontal deviation plot on and off.
“Show Vert Plot” will turn the vertical deviation plot on and off.

“Show Width Plot” will turn the pipe diameter size plot on and off.

View 3D Reports.

By clicking on the Additional Tab or from the DVD selecting the Additional Reports page, the user may start the 3D ScanCam viewer for this inspection.

The link shown in the reports will navigate the user to the ScanCam folder for this session. To open the ScanCam 3D viewer, double-click on the start.cmd icon.

The Rausch 3D ScanCam viewer will now open.

The Pipe Complete and Pipe Sector options allow the user to view the entire pipe or sections of pipe. While the pipe sector option is selected, the user may slide the slider below pipe sector option to the right or left to move along the pipe. The number of segments to show may be adjusted by moving the up/down value of the number of displayed segments box.
To change the red and yellow deflection values, the user may move the Red percentage and Yellow percentage value up/ down box values. To change the default settings before a disc has been burned to a DVD, the ScanCam3d.ini values may be adjusted. Modifying the GELBGRENZE value will change the yellow deflection value. Changing the ROTGRENZE value will modify the default red deflection value. Note that the values must have a decimal value, but a comma is used rather than

a period. For instance, 5.0 would be entered in as 5,0.

Laser Video Micrometer Measurement.

POSM’s Laser Video Micrometer allows the operator to make accurate measurements of observations inside of
a pipe. The distance between the lasers is known ahead of time and entered into the calibration box. By calibrating the screen, POSM will count the pixels of the drawn line and give an accurate distance measurement of that line. For the most accurate measurement, zoom in as close as possible to the defect while keeping the laser lines in view of the
camera. The more pixels used in the measurement, the more accurately POSM can measure.
After enabling the POSM Measurement Utility, set the “Enter Length of Targets” box with the distance between the laser dots or lines. If using imperial units, enter this in inches. If using metric, use millimeters.

POSM Pro // Operating Rausch ScanCam within POSM. // Page 6

The measurement utility must be calibrated each time a measurement is taken. To calibrate the measurement utility, right-click on the screen and drag a blue line between the laser points. This will let POSM know how many pixels per inches or mm’s there are on screen. Anytime the camera is moved or zoomed, the calibration must be redone.
• Click Right (or Left) Button on Macro to bring to 90.
• Click on Measure tab.
• Turn on lasers.
• Zoom to max pixels of lasers on screen.
• Click Magnify to show mag of screen to calibrate.
• Check Target Width to make sure it’s correct for the pipe size (V of laser).
• Right-click and drag blue line from center of laser to center.
• Select Observation to place measurement into.
• Right click on Screen hold and drag a line to end of object to measure.
• POSM will then load the calibrated length into the field that is set in POSM Setup of the Measurement Utility.

• Add the observation.

Helpful Hints.

• Start with single point scan. Use the picture to make
sure the camera is centered. Put diameter measured into inner diameter box for whole run scan.
• The less centered the camera, the less accurate the data.
• Run tires with less air pressure if system is in corrugated pipe to lessen bounce.
• Initiate scan inside the pipe, not in the manhole. Running ScanCam in the manhole will create large spikes in the report graph.
• Make sure it is pitch black in the pipe and manholes when running ScanCam. Cover up any sources of light into the pipe.
• The slower you scan, the more accurate the measurement results. See Speed Density Chart.
• After whole run line measurement, if the graph indicates any issues or spikes, go to spot/s and run a single

point scan.
