Pilot Pipe Dectection with UAV (2016)

During the summer of 2016 Shore performed a pilot study together with the waterboard Scheldestromen to investigate the applicability of R,G,B colour- and infrared sensors deployed from UAV’s for the observation of piping along dikes and other water retaining bodies. Hereto several test measurements have been performed along the Gouweveerse Sea dike in the Netherlands where sand-carrying pipes are clearly visible.

The results showed that it is possible to detect pipes with an infrared sensor. However, by the time of this pilot the Infrared technology was found to be unsuitable for automatic pipe detection. Differences in emission between grassland, shading and colour differences on the surface cause similar Infrared images, making it difficult to automatically isolate potential piping locations. Detection with regular R,G,B images proved to be possible.

The pilot gave the waterboard insight in the possibilities of new UAV applications on their professional practice. Based on this pilot they saw possibilities for ‘digi-inspection’ with R,G,B, imagery obtained by UAV’s and collecting an image archive of watercourses and flood defences.
