Laser Profiler System
What is it?
-
The Laser Profiler is a stand-alone, snap-on tool for use with a CCTV survey system/camera to collect survey data and create pipeline reports, including fault measurements and internal pipeline features.
-
Attaches to existing CCTV crawler camera, using machine vision software to analyze CCTV images.
-
The Laser Profiler measures pipe size, laterals, water levels and other features.
-
Performs automatic analysis of pipe ovality and capacity at a rate of 30 times per second.
-
The Laser Profiler enables the contractor, municipality, or engineer to determine internal pipeline conditions before, during, or after rehabilitation.
-
For use within 5" to 72" pipe diameters.
Laser profiling is an advanced technique for determining the accurate surface profile of a pipe or other structure. The method projects a laser generated source onto the interior of a pipe or structure wall to determine accurate measurement of the structure.
Laser profiling uses include:
-
Determination of the structural shape, cross sectional area and defects
-
Estimation of debris quantity
-
Calculation of pipe capacity before and/or after cleaning
-
Rehabilitation/Replacement design information to improve selection of method
-
Post rehabilitation verification of lining and subsequent capacity
How It Works:
-
A ring of laser light is projected onto the internal pipe surface
-
Laser image is in the field of view of the camera while the camera moves through the pipe
-
Analysis is performed on the ring of light using the Laser Profiler software to build a digital pipe profile
-
For use with live or pre-recorded video (tape, CD, or DVD) Ovality - The Ovality function calculates the “q” (as per ASTM F 1216, the internationally recognized standard for CIPP rehabilitation).
-
Capacity - The Capacity (X-sectional Area) function calculates the cross-sectional area for each profile and normalizes the results against the expected internal pipe area.
-
Interfaces with CCTV software.
-
Delta - The Delta calculation finds the maximum and minimum pipe radius for each profile.

Examples of quantifying lift in liner using both the
manual and the automated digital measurement
methods.
Automated Analysis- The software uses machine vision. Machine vision is used to find the video image of the laser profile (red laser line). Each frame of the inspection video is analyzed to build a digital profile of the pipe.

Laser profiling technology that adds new dimensions to conventional pipe inspection methods is now available in Canada.
The Cleanflow system laser profiler measures the interior ovality of any type of pipe to assist in accurately verifying the overall condition of an existing pipeline or to confirm that installation of new pipe meets ovality specifications.
The laser profiler is not intended to replace conventional CCTV inspections, but to gather data about the pipe ovality, slopes and other information that are beyond the capabilities of standard CCTV methods.
Three-Dimensional (3-D) Display
The pipe data can be displayed as a fully interactive three dimensional model. The user has the ability to zoom in and move around the model to find and display points of interest. Reporting is available using the Profile Report. The model can be displayed using two methods:
-
Topographic display: A user defined topographic scale is having been exceeded. In this example, the red rings highlight where applied to highlight where the actual pipe radius is greater than the expected internal radius (shades of yellow, orange and red) or less than the expected internal radius (three shades of blue).
-
Capacity and Ovality display: Cross-sectional coloring allows users to easily locate sections of pipe where user defined ovality and capacity thresholds capacity threshold of 10.2% has been exceeded.
