Design of Fast Performance Testing & Analysis System of Road Traffic Markings
Jun Ma, Wen Ying Su · Applied Mechanics and Materials · 2012
In view of the heavy workload and the lack of objective measurement and evaluation standards of disrepair rate during the performance testing of road traffic marking, this paper is designed to present a system that can be installed in an automobile and automatically track and analyze the performance of traffic marking. The system consists of a carrying vehicle, GPS, IMU, line-array cameras, frame grabbers, data acquisition software and data analysis software. Based on image enhancement and image segmentation technology, the system is designed with a set of effective road traffic marking automatic detection algorithms, which can automatically measure and analyze the properties of road traffic markings, such as disrepair rate, width, length, longitudinal distance, horizontal distance and so on.
