A new threat degree analysis method of abandoned objects based on dynamic multifeature fusion in urban traffic

Abandoned objects in a road can be a potential threat to urban traffic. In this article the authors present a new threat degree analysis method of abandoned objects, which is based on dynamic multifeature fusion to detect the abandoned objects and analyze the threat degree automatically. The image sequence is acquired with a visible sensor installed at overbridges, and is processed by a PC-based image-processing system. In this method, the authors first put forward a multivehicle tracking algorithm to acquire the vehicles' moving information as preprocessing. Then they extracted the dynamic features and built a security threat model upstream of the abandoned object to facilitate further analysis. Finally, they proposed a fusion decision method, based on dynamic multiple features, to analyze the threat degree. The experiments show that the developed method can determine the threat degree of abandoned objects well and truly, and it is appropriate in the intelligent traffic monitoring system.
