Introduces the bow of pantograph, system designing of dynamic envelop line of the pantograph machine vision and camera calibration. The principle of the dynamic envelop line detection and algorithm of template matching are illustrated in this paper. The experimental results show that the analysis on dynamic envelop line of the pantograph has strong acceptance and high precision. This method offer the real bases and theoretical foundation to detection of the dynamic envelop line of the pantograph.
