CleverScan performs a comprehensive, fully automated assessment of manhole condition in just two to three minutes. It captures visual and dimensional data, and presents the user with three powerful deliverables: 

  • A flat scan with detailed image data covering every inch of the manhole wall
  • A dense point cloud for 3D visualization of the manhole structure and easy CAD integration
  • A virtual view inside the manhole, where an operator can pan, tilt and zoom to areas of interest.

With the press of a button, the system’s probe descends into the manhole, capturing image data using five HD cameras and building a dimensional profile using an array of four lasers. An on board rangefinder controls descent and determines when the scan is complete. Scan data is immediately transferred to a laptop running CleverScan software, where it can be viewed, annotated and shared.  866/936-8476;
