摘　　要：无人机倾斜摄影技术能够快速、高效地获取三维实景模型数据,但通常应用于大规模建筑群和复杂单体建筑。本文针对合院民居、历史村落建筑群体特征,基于高效无人机倾斜摄影技术,以三维建模质量、精度和效率为指标,比较了环绕式、弓字形和井字形三种飞行航线,给出了环绕式航线的最佳飞行高度、角度等拍摄参数,并提出了增加小半径补飞的航线优化方法。本研究为合院民居数据图像采集与三维建模提供方法支撑,有利于建筑遗产的数字化保护和建筑文化传承更新。UAV tilt photography technology can quickly and efficiently acquire 3D real-world modeling data,but it is usually applied to large-scale building groups and complex single buildings.This paper compares the three flight routes of wrap-around,bow-tie and tic-tac-toe based on highly efficient UAV tilt photography technology for the characteristics of residential compounds and historical villages,takes 3D modeling quality,accuracy and efficiency as the indexes,gives the optimal flight height,angle and other shooting parameters for wrap-around routes,and proposes the route optimization method to increase the small-radius complementary flights.This study provides methodological support for the image acquisition and 3D modeling of the data of courtyard houses,which is conducive to the digital protection of architectural heritage and the renewal of architectural culture inheritance.
