Abstract: Aiming at the problems of model breakage, texture deformation, suspended objects and low detail performance in 3D real scenes in near-ground perspective or when facing complex and special objects, this paper proposes a scene-enhanced display method. Using the corrected undistorted image, find the target image that matches the most similar to the scene and superimpose it on the 3D model accurately to complete the visual fusion and natural transition between the 2D image and the 3D model. And it realizes the dynamic scheduling and real-time rendering of images during the 3D roaming process to support the continuous enhanced display of super large scenes. Practices show that this method can not only make up for the insufficient visualization of the realistic 3D model and improve the visual browsing effect, but also can combine the latest oblique images to enhance the currency of the scene expression, thereby enhancing the promotion and application value of 3D real scene. The research results can contribute to the development of natural resources management, land and space planning, emergency disaster relief, urban governance and other fields.

Key words: 3D real scenes, oblique image, visual fusion, enhanced display
