摘要: 自然资源外业核查是自然资源调查重要的一环, 该文针对传统自然资源调查外业核查过程中存在的工作效率低、有安全风险等问题, 提出了一种基于无人机地理信息视频技术的外业核查应用方案。首先针对无人机地理信息视频技术的特点, 结合自然资源外业核查工作的需求, 将核查图斑分为地类判断和量测判断2种类型, 并针对不同类型进行无人机地理信息视频的采集设计; 然后将采集的无人机地理信息视频与地理信息系统(geographic information system, GIS)平台联合进行图斑的判断量测。结合生产实践对设计方案进行了测试, 测试结果表明, 该方案能够提高图斑外业核查的效率, 量测精度能够满足实际生产的需求, 且弥补了地面拍照的局限性, 降低了安全风险。Abstract: Field verification of natural resources is a vital part of natural resource surveys. To address issues such as low efficiency and security risks encountered in traditional field verification methods, this study developed an application scheme for field verification utilizing UAV-based geographic information video technology. First, this study examined the characteristics of UAV-based geographic information video technology. Based on these characteristics, as well as the requirements of field verification, the features for the field verification were categorized into two types: land use classification and measurement assessment. Subsequently, the UAV-based geographic information video acquisition was designed for each type. The collected videos were then combined with a geographic information system (GIS) platform for feature evaluation and measurement. The application scheme was tested based on production practices. The test results indicate that the proposed scheme can improve the efficiency of the field inspection, with the measurement accuracy meeting the demand for actual production needs. Furthermore, the scheme can overcome the limitations of ground-based photography and reduce safety risks.
