Abstract
Abstract. With the application of UAV Oblique photography, rapid 3D real-time modeling based on aerial image data has become a new technology in the field of 3D modeling. In view of the current poor mapping and inability to reuse the basic surveying and mapping data in the publicity and display, dynamic planning, etc., based on the UAV photogrammetry technology that is used to rapidly and accurately collect image data of the Longji terraced scenic spot in Guilin, Guangxi, this paper develops a platform by 3D real-time modeling technology with the combination of the high-tech such as digital mapping to realize the three-dimensional navigation and smart tourism of the scenic spot. The practical results show that the application can better meet the actual needs of high precision, large scale, wide audience, strong interaction, etc., which effectively alleviates the contradiction between the protection and utilization of cultural resources in cultural tourism, expands the cultural resources audience, and provides high-tech support to the cultural tourism.

Summary
With the continuous improvement of the economic level of our people, traveling has become a part of the lives of many people. With its high resolution and high realism, UAV tilt photography can truly restore the true natural landscape, which is conducive to the protection of scenic spots, especially the protection of geological relics, the promotion of popular science knowledge and the visual display of natural landscapes, attracting Visitors watch, providing users with a more realistic virtual travel method, providing a new way for the scenic spot to display their own image and resources To this end, the basic surveying and mapping data of tourist attractions in the aspects of propaganda, display and dynamic planning are not current and cannot be reused (Guan, Sun, 2017). RELEVANT THEORY AND TECHNICAL SUPPORT OF UAV TILT PHOTOGRAPHY MODELING TECHNOLOGY IN VIRTUAL TOURISM
