Abstract

The goal of the research is to determine the potential of laser scanning methods for accurate, non-invasive assessment of the changes in the inner pipe profile of concrete sewer pipes. The main research question is: ‘How accurate is the laser profiler when measuring deteriorated sewer pipes?’ In the research egg shaped concrete sewer pipes were measured under laboratory conditions. The used experimental setup consists of an old concrete, egg shaped sewer pipe. At the front and back of the pipe a ramp is placed to ensure a smooth entrance and exit of the inspection camera. The recordings from the laser profiler are analyzed with Matlab to determine the accuracy.
