乡村振兴中消费级无人机摄影测量的应用与评估

Application and Evaluation of Consumer-grade UAV Photogrammetry in Rural Revitalization

在实施乡村振兴战略的过程中,规划工作开展的同时伴生了对所规划地区地理信息数据的需求。规划设计过程中,对于非测绘专业的设计人员,获取所需地理信息数据大多依赖于精度有限的卫星地图,难以满足规划过程中进一步深化的需求。无人机摄影测量的结果经处理,可转化为数字正射影像图、数字高程模型和真实三维模型等多种成果,为乡村规划的设计人员提供认知和数据上的支持。文章以作者的实践案例为基础,介绍无人机摄影测量的技术流程、注意事项及成果使用。

In the process of implementing the rural revitalization strategy,the planning work is accompanied by a demand for geographic information data in the planned area.In the planning and design process,for non surveying and mapping professionals,obtaining the required geographic information data mostly relies on satellite maps with limited accuracy,which is difficult to meet the needs of further deepening in the planning process.The results of UAV Photogrammetry can be transformed into various results such as digital orthophoto maps,digital elevation models,and real 3D models after processing,providing cognitive and data support for rural planning designers.Based on the author's practical cases,the paper introduces the technical process,precautions,and application of UAV Photogrammetry.
