Research on automatic analysis method of power engineering quantity based on multi-source data

In the process of power engineering construction, there is a lack of efficient automation means for the management of construction quantities. In this study, an automatic analysis system of engineering quantity of electric power engineering based on BIM 3D model, oblique photography and laser point cloud technology is proposed, with engineering quantity database as the core. Through the fitting of multi-source data, the three-dimensional model of the real-time progress of the site is matched with the engineering quantity of the database, and the real-time engineering quantity of the engineering site is automatically calculated, which is intended to solve the lack of efficient and automated means of engineering quantity statistics at the construction site of electric power engineering.
