Three-dimensional laser scanning-based precise troubleshooting device for urban concealed culvert discharge port

The utility model provides a three-dimensional laser scanning-based urban concealed culvert discharge port accurate troubleshooting device. The three-dimensional laser scanning-based urban concealed culvert discharge port accurate troubleshooting device comprises a three-dimensional laser scanner unit and one or more target units. According to the utility model, the three-dimensional coordinates of the discharge port, the plane position of the hidden culvert, the longitudinal and transverse sections of the hidden culvert and the three-dimensional modeling of the hidden culvert can be accurately measured under the condition of meeting the discharge port troubleshooting requirement, and personnel do not need to go down the hidden culvert for operation, thereby reducing the safety risk of operation. 本实用新型提供了一种基于三维激光扫描的城市暗涵排口精准排查装置，包括三维激光扫描仪单元和一个或数个标靶单元。本实用新型可以在满足排口排查要求情况下，精确测定排口三维坐标、暗涵平面位置、暗涵纵横断面及暗涵三维建模，同时人员不用下暗涵作业，减小作业的安全风险。
