Three-dimensional modeling technology based on oblique photography assisted BIM and GIS

Abstract

The invention discloses a three-dimensional modeling technology based on oblique photography assisted BIM and GIS. The method is characterized in that high-resolution images at the same position and at multiple different angles are taken as the basis of oblique photography aerial survey, three-dimensional modeling is carried out through calculation, a BIM technology is used for processing buildingmonomers and internal information, and spatial geographic information data are integrated and analyzed in a GIS through data conversion. The invention relates to the technical field of three-dimensional modeling, in particular to a three-dimensional modeling technology based on oblique photography assisted BIM and GIS. The three-dimensional modeling technology can automatically establish the three-dimensional model, has the characteristics of high efficiency, high precision, high authenticity and low cost, combines the BIM to carry out refined internal processing on the building model, carries out three-dimensional visualization on the model processing through the 3D GIS, has the characteristics of rapidness and reality in modeling, and has the characteristic of space visualization in management and analysis. The problems that traditional three-dimensional modeling is low in efficiency, high in cost and insufficient in model precision, and geographic information management cannot be carried out are solved.

Benefits of technology

This patented describes an improved method for measuring elevation levels on surfaces that may be difficult or expensive to measure manually due to their shape. It uses images from different angles to create models without any errors caused by human factors such as shading or unevenness between areas. By adding these altitude controls at specific locations within each section of the surface, accurate measurements become easier than previously needed. Additionally, this technique allows users to see how things look inside them more clearly during construction process while also showing it's true state over time. Overall, this new approach improves the quality of buildings built using digital techniques like laser scanning (LSC).

Problems solved by technology

The technical problem addressed by this patented method is how to create accurate virtual reality (VR) worldwide with advanced tools like BIM for urban planning purposes while also utilizing obliquely photographed images collected through traditional techniques such as ground photosensors.
