摘　　要：轨道交通区间规划监督测绘翔实记录隧道区间的规划要素,核实工程建设与规划审批的一致性。文章采用集成惯导的移动三维扫描结合隧道已有CPⅢ控制点绝对定位的方式进行区间规划测量,此方法的测量精度满足验收测量要求。从融合校正后的扫描点云,提取区间点线要素,结合区间规划要素,生成规划要素图。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 CPⅢcontrol 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.
