Fault Detection


Manual process to inspect sewer pipelines to log defects using a camera on a bogie. Very time consuming and limited coverage.


Computer vision based fault detection, automating the inspection process and increasing coverage by over 3 fold.

The How

  1. Understand the inspection process and camera data captured and how it is labelled
  2. Data Engineering phase to improve data sets
  3. Develop a transfer learning model for image classification
  4. Develop a Sewer fault detection tool to help label videos correctly and quickly
  5. Provide alerts on the exact locations of blockages, cracks and intrusions in the network
