The invention discloses a dynamic measurement method for a subway rigid contact network, and the method comprises the steps: scanning a subway tunnel through a dynamic measurement instrument, and obtaining three-dimensional point cloud data; removing interference data, and segmenting three-dimensional point cloud data of the busbar positioning bracket and the adjusting bolt; taking a plurality of different samples, repeatedly and dynamically identifying and measuring, and repeatedly and iteratively determining the model characteristics of each sample; and applying the cloud data characteristics to dynamic detection, and calculating the height difference between the contact line guide height pull-out and the busbar bracket and the level and/or height difference of the adjusting bolt relative to the contact line. According to the method, a non-contact detection method is adopted to continuously scan and measure the rigid catenary through the high-precision laser radar, a detection result is rapidly and accurately given, and the measurement precision is high; according to the method, the characteristic coefficient models of the busbar, the contact line, the busbar positioning bracket and the adjusting bolt are trained by adopting the three-dimensional point cloud, so that the tunnel davit is quickly and effectively judged, the detection speed is high, the result is accurate, and the method is not interfered by the environment.
