摘　　要：本文结合环境保护与资源调查应用领域,通过无人机倾斜摄影测量完成试验区外业采集,针对山区、复杂建筑等高差大、纹理弱等问题进行了针对性设计,增加了航飞尺度的多样性,使用优化后的SFM_MVS算法联合解算多尺度数据,弥补了普通消费级相机在大高差区域的一系列问题,成功完成了广州某重点区域的山林地、古建筑实景三维模型建设。模型完整性相较传统无人机摄影测量航飞结果提升约30%。本文的航飞设计与联合解算方法为复杂区域的实景三维模型采集和环境资源调查提供了有益探索。In the field of environmental protection and natural resource survey applications,this paper combines the external data collection of oblique aerial photography and measurement using UAVs in the experimental area.It aims at issues such as large elevation differences and weak textures in mountainous areas and complex buildings,and designs specifically for these challenges.By increasing the diversity of flight scales,the paper uses an optimized SFM_MVS algorithm to jointly process multi-scale data,which compensates for a series of problems that ordinary consumer-grade cameras face in areas with large elevation differences.The construction of 3D realistic models of mountains,forests,and ancient buildings in a key area of Guangzhou has been successfully completed,with the completeness of the model improved by about 30%compared to the results of traditional UAV photogrammetry flights.The flight design and joint processing methods presented in this paper provide a beneficial exploration for the collection of 3D realistic models and environmental resource surveys in complex areas.
