One of the major threats to the safe and normal operation of the power transmission lines is the external force or intrusion incurred by construction trucks. Especially for the urban area, construction of truck cranes is increasingly becoming a leading cause to the damages of power transmission lines. However, the conventional monitoring method for protecting power transmission lines is to conduct a routine inspection or patrol on the transmission line network periodically, which is time-consuming and laborious. In this paper we propose a video surveillance system for automatic tracking the dangerous strength such as construction cranes. The criterion of context formation aims to detect the jib of crane and compute its extension angle. Once the crane is parked over a certain period of time, or the jib extension angle exceeds predefined thresholds, warning messages will be sent to power line supervisors. The experiments show that the system is able to achieve automatic detection of truck cranes and protect transmission lines from their careless constructions.
