360 Degrees 3D Sensor for Water Conduits Inspection


INO offers a technology for a fast and accurate pipe inspection of sewers, aqueducts and culverts to measure geometry (diameter, ovality, fittings) within the various water lines and to identify defects. Thus, it is possible to better plan and prioritize interventions following the inspection. Also, the system allows better control of the rehabilitation process in order to optimize costs.


The solution is a 3D sensor providing 360-degree images from the inside of the conduits thanks to laser profilometry technology. It detects and locates the smallest defects such as cracks and corrosion very early in the process of degradation. Moreover, it allows to locate the connections to the secondary conduits, thus facilitating the cladding work. Once installed on a autonomous pipe crawling device or on a ‘’sled’’, this sensor becomes the perfect conduit inspection tool.

The video below provides an example of what kind of data the sensor can gather and display:

  • Works planning
  • Control of the rehabilitation process
  • Automated and dimensional inspection of conduits
  • Geometric measurement of defects for inventory purposes (ovality, dents and holes, corrosion, cracks)
  • Positioning of critical characteristics before and after repair and rehabilitation
  • Cleaning check
  • Validation at installation
  • Detection of water leaks and clogging


  • Internal conduit diameters: between 6 and 30 inches
  • Inspects iron cast, PVC, HDPE and brick surfaces
  • 50 profiles per second (1 mm to 3m / min depending on the axis)
  • 1 mm radial resolution (depth)
  • 0.25 ° azimuth resolution (perimeter)
  •      1440 points per profile
  •      0.7 mm in a 12-inch conduit

  • Real-time profiles
  • Complete 3D rendering in minutes



A mature technology, the laser profilometry technique has been successfully used for the design of sensors that can detect 0.02 in. (0.5 mm) cracks at a distance of 6.5 ft. (2 m) and at a speed of 65 mph (100 km/h) for road defect detection applications. INO produces these units on an ongoing basis.
