Abstract: In order to better understand the working principle of laser scanning technology and the whole process of 3D information acquisition, and to overcome the limitation of practical teaching in existing laser scanning course, especially airborne ones that is restricted by the practice sites, this paper introduces the self-developed laser scanning instrument for 3D data collection based on the aviation simulation platform (ASP) in the Shahe campus, China University of Mining and Technology-Beijing. The scanning instrument is developed by a single-pulse scanner and a rangefinder. First, this paper introduces the mathematical principle of the scanning instrument. Then, we design the method and scheme of 3D data acquisition in practical process with the developed scanning instrument. Finally, we conduct the experiments on 3D data acquisition and quality evaluation with the developed scanning instrument. The experimental results show that the accuracy of the scanning instrument for point clouds collection is better than 99%, which can provide effective practical support for practical experiments, innovation training and graduation project. Besides, the developed scanning instrument can be promoted to engineering applications such as storage square volume accounting.
