Abstract

Underground infrastructural objects such as sewage and water supply networks, which mainly consist of pipes or collectors, are exposed to solid corrosion of concrete and metal, significantly reducing their service life. Today, laser 3D scanning, which allows you to create a three-dimensional map of the pipe's inner surface, is considered one of the promising methods of monitoring sewer networks. Specialists use wheeled robots or aerial platforms with stereo cameras and lasers as devices for laser scanning. The main advantage is that 3D maps can easily detect and quantify structural defects on the pipe's inner surface. Creating a three-dimensional model and its subsequent analysis makes it possible to examine the drainage network in the shortest possible time to find cracks and sealing violations. This model helps to determine the nature of the flow of waste liquids; establish the presence of deposits; assess the degree of wear and corrosion of pipes; insulation condition; integrity and quality of the network after construction or repair. Laser scanning will prevent negative environmental impact, preserve ecology, and not harm the life and health of workers.
