Rail transit section planning supervision surveying and mapping records the planning elements of tunnel section in detail,and verifies the consistency between engineering construction and planning approval.In this paper,the moving three-dimensional scanning of integrated inertial navigation system combined with the absolute positioning of existing CPⅢ control points in tunnel is used for interval planning survey.The measurement accuracy of this method meets the requirements of acceptance survey.From the scanned point cloud after fusion and correction,the interval point and line elements are extracted,and the planning element map is generated by combining the interval planning elements.
