Abstract
In order to satisfy the demand of delicacy management in chemical industry park for spatial data acquisition, this paper uses terrestrial 3D laser scanning technology to quickly obtain massive 3D spatial data for measurement in the chemical industry park. Taking one chemical industry park in Chengdu as an example, before 3D laser scanning, it’s necessary to firstly implement field exploration and understand general conditions and internal facilities in the park, especially key measurement and control areas, and prepare a detailed scanning plan. Pre-processing of internal data can be implemented to obtain panoramic 3D data of the chemical industry park, further extract the data and conduct 3D modelling and relevant analysis, so as to achieve 3D measurement and control of the park. Results show that this method is characterized in simple operation, quick measurement, high accuracy and strong practicability. So, 3D laser scanning technology can be used for 3D measurement and control in chemical industry park, so as to quickly obtain 3D spatial data in the park and measure more accurately.
