Results of validity analysis.

Tilt photography of unmanned aerial vehicles (UAVs) is widely used in urban management, cadastral mapping, disaster monitoring and other fields, but there are few innovative applications in online tourism. In this study, empirical design and usability testing methods were adopted, advanced positioning technology and Cesium engine were used to build a 3D real online travel application based on tilt photography, and the interactive function was realized through JavaScript language dynamic interactive function script. Meanwhile, combined with the questionnaire survey, the mobile application Rating Scale (MARS) was used to evaluate the function and quality of the application. The results show that engagement, functionality and aesthetics have no significant influence on user perception. Information quality and subjective quality of application have significant positive influence on user perception, and the influence of information quality is more significant. This study extends the application of oblique photography in tourism and provides experience for the development of tourism digitization.无人机（unmanned aerial vehicles, UAV）倾斜摄影技术已广泛应用于城市管理、地籍测绘、灾害监测等领域，但在在线旅游场景中的创新应用相对较少。本研究采用实证设计与可用性测试方法，结合先进定位技术与Cesium引擎，构建了基于倾斜摄影的三维实景在线旅游应用，并通过JavaScript语言动态交互脚本实现了交互功能。同时结合问卷调查，采用移动应用评分量表（Mobile Application Rating Scale, MARS）对该应用的功能与质量进行评估。研究结果表明：用户参与度、功能特性与美学设计对用户感知无显著影响；信息质量与应用主观质量对用户感知具有显著正向影响，且信息质量的影响更为突出。本研究拓展了倾斜摄影在旅游领域的应用场景，为旅游数字化发展提供了实践经验。
