Study on OCS Dynamic Geometric Parameters Detection Based on Image Processing
In order to assure that the high speed train can operate normally,it is necessary to ensure the security of catenary and detect catenary geometry parameters frequently.Traditional detection methods will reduce the similarity between detection pantograph and actual pantograph,which results in the error of catenary detection parameters.In this paper,the feasibility of detecting catenary dynamic geometric parameters using roof camera is analyzed.An image processing based non contact detection method that calculates and detects contact line height and dynamic pull out value is proposed.The experimental results show that the system is feasible,and has the characteristics of simple installation and high precision.
