Laser-based Metrology for Quantitative Inspection of Water Pipe

The PipeDiver is a free-swimming platform developed by Pure Technologies, which can carry sensors and devices for non-destructive inspection of in-service water pipelines. CCTV (closed-circuit television) inspection is a well-adopted method, which employs a CCTV camera on the platform. General, the CCTV inspection can only provide qualitative results about pipe condition. To achieve quantitative inspection, such as the measurement of pipe joint gap, precise laser-based measurement is preferred. This research is to integrate laser sensor with digital camera on the PipeDiver platform to implement the gap measurement. The principle is to use camera to capture the laser profile projected onto the gap and use image processing to calculate the width from the laser profile. The automatic processing algorithm will be developed as a software prototype by the intern for Pure Technologies.
