With the continuous maturity of UAV (Unmanned Aerial Vehicle) tilt-ed photogrammetry technology, its data acquisition methods have ad-vantages such as high speed, high efficiency, high precision, low cost, etc., and can realize three-dimensional automated modeling. The com-bination of UAV tilted photography technology and Geographic In-formation System provides a new way of planning for cultural herit-ages conservation. This article combines examples, aiming at the prob-lems of low efficiency, few data types, and lack of rational analysis of basic data in the early period of cultural heritages conservation planning, and proposes the use of UAV-assisted pre-investigation re-search to obtain many types of precise data in large quantities within a wide range over a short period of time. Real-time data collected by UAV is used for error correction and spatial statistics of topography maps as well as rapid processing of large-scale research. Automated three-dimensional modeling based on tilted photogrammetry tech-niques is used to establish fine models of building monoliths, and to analyze the status of cultural heritage. Combining the DLG data from ArcGIS software that is used for spatial analysis of the surrounding environment of the cultural heritages, the application of tilted photo-graphic data of UAV in conservation planning and management is ex-plored to improve the scientificity and operability of cultural heritage conservation planning. Applying UAV tilted photography to cultural heritage conservation planning, the working methods and analysis ide-as introduced in this artical will become an important scientific and technological means in the conservation of cultural heritage.
