土地调查中无人机摄影测绘技术的应用研究

当前无人机技术发展迅速，基于无人机的摄影测绘技术在土地调查中的应用是未来的大趋势。首先研究了无人机遥感系统，共由5大部分构成，分别为飞行平台、导航控制系统、传感器、地面工作站以及数据处理系统。在对试验区域基本情况进行简要介绍的基础上，分析了无人机影像获取的基本过程与步骤，对影像图片数据处理中的关键技术进行了分析。通过人工方式对试验区域内的土地类型进行了内业解译，同时选择部分区域开展外业实地调查工作，将两者结果进行对比分析，发现内业解译结果精度超过95%。若使用分辨率更高的摄像设备可以进一步提升内业解译的精度。

Application research on unmanned aerial vehicle photographic surveying and mapping technology in land survey

The current UAV technology is developing rapidly，and the application of UAV-based photographic surveying and mapping technology in land surveys is a general trend in the future.First，the UAV remote sensing system was studied，which was composed of 5 parts，which were the flight platform，navigation control system，sensor，ground workstation，and data processing system.On the basis of a brief introduction to the basic situation of the test area，the basic process and steps of UAV image acquisition were analyzed，and the key technologies in image data processing were analyzed.The internal interpretation of the land types in the test area was carried out manually.At the same time，some areas were selected to carry out field surveys.The results of the two were compared and analyzed.It was found that the accuracy of the internal interpretation results exceeded 95%.The use of higher-resolution camera equipment can further improve the accuracy of interpretation in the office.
