DLG Production and Quality Control Technology Based on Realistic 3D Models
Abstract：Digital Line Graph (DLG) is an important component of urban basic geographic information data, and its production efficiency and quality control directly affect the quality and safety of engineering construction. This paper proposes a DLG production process and quality control method based on realistic 3D models, combs and summarizes the key technical points and quality control methods in each production link. Taking a 1:1000 DLG project in a certain town of a city as a case study, it describes the practical application of DLG production and quality control technology based on realistic 3D models. By constructing a realistic 3D model, DLG drawing was completed, breaking through the limitations of traditional line drawings relying on field surveys, while overcoming the limitations of stereoscopic glasses observation of simulated 3D models, and effectively solving quality issues that arose during the production process.
