Study on the Seamless Integration Technology of Oblique Photography Real-time Model Base on AutoCAD

The application of oblique photography real-time model is more and more extensive in recent years. In order to meet the demand of putting oblique photogrammetry data in AutoCAD for displaying and editing in the land and planning departments, aimed at the characteristics of AutoCAD and oblique photography real-time model, this paper discusses the key integration technology of oblique photography real-time model and AutoCAD based on the secondary development technology of OSG and ARX, such as the oblique photography model data conversion and the fast dynamic LOD display of oblique photography real-time model based on the secondary development technology of OSG and ARX. The applied example shows that the method proposed in this paper is suitable for the analysis and display of the oblique photography real-time model directly in AutoCAD, and provides a certain reference value for the application of oblique photography reality model for the S/M units.
