Abstract
The three-dimensional laser scanner in road final survey application compared with the conventional mode of operation greatly improves the operation efficiency, reduce the amount and intensity of labor and industry. Due to the three-dimensional laser scanner can quickly collect a large amount of point cloud data, virtual reproduction of the surveyed area terrain, compared with the traditional operation method, it has incomparable advantages. It briefly introduces the working principle of 3D laser scanning technology, introduces in detail the 3D laser scanning technology in road final survey in indoor and field work method, and the testing of the accuracy, of three laser scanning technology in he related engineering application provides a very good reference.关键词
