Abstract: Many cities in China have basically realized the application of digital three-dimensional modeling technology in planning and planning before the three-dimensional simulation program management, have effectively improved the quality and efficiency of the planning approval.However,by the project planning and acceptance of data collection restrictions,planning verification using three-dimensional platform of the city is one of the few. With the development of 3D laser scanning equipment and technology, micro long distance and high precision 3D laser scanning equipment has entered the application stage,rotor UAV equipped with mini 3D laser scanner operating mode,let the small area fast and accurate 3D model become possible.Through a building completed 3D mapping test case,this paper tested the application area of 3D laser scanning technology,the number after the management objective of the project construction and project schedule management,real,accurate,intuitive and detailed and accurate understanding of the actual project construction situation,improved the efficiency of planning and planning management after batch verification that greatly promoted the planning management more scientific and efficient.

Key words: three-dimensional laser model, three-dimensional real image model, laser point cloud, planning verification, completion surveying
