Application of Multi-Sensor Road Feature Detection and Mapping in Kazakhstan and Development of Pole Detection and Analysis Procedure

A mobile multi-sensor monitoring system has been actively used in Kazakhstan for monitoring the road infrastructure. The main goal is to justify repair measures and to eliminate technological errors in the construction of new and reconstruction of existing roads, as well as to create an extensive database on the transport and operational condition of roads and road structures. This paper provides a short discussion of the currently adopted procedures to implement this approach. Although almost all data collection is automated, the detection of poles near the roads is still conducted manually. This paper is focused on the automation of pole detection and its detailed analysis to obtain the characteristics vital for its structural health monitoring. It is based on an analysis of point clouds collected by a laser scanner usually installed on top of the mobile monitoring system. A framework for pole detection and its assessment is presented.
