Application Of Unmanned Aerial Vehicle Mapping Technology In Land Comprehensive Renovation Managemen

The traditional digital mapping technology,in addition to the process is relatively complex,also need to devote a lot of manpower,material resources,to participate in the mapping of the technical staff of the theoretical and practical ability are very high,in the process of each link are required to be careful enough to avoid errors,and finally into the map,but also in the field of the mapping process in the leak detection,In the process of drawing and so on,to ensure that the ground and surface objects are in the same shape and correct position.With the development and progress of computer technology,surveying and mapping science in recent years,the rapid development of economy and the speeding up of infrastructure construction,the new requirements for the speed of the updating of the existing topographic map and its wide application in various fields are put forward.Unmanned aerial vehicle digital terrain surveying and mapping technology specifically to unmanned aircraft as the carrier,with the help of the aircraft attached to the photographic camera imaging equipment,and then through the computer software tools to obtain the image files processing,matching,extraction of UAV photogrammetry image information,and finally obtain digital topographic map method.The digital terrain surveying and mapping based on unmanned aerial vehicle has high efficiency,low cost and strong maneuverability,and it has obvious advantages in the work of digital mapping,which can reflect the topography and landform of the surveying area realistically in computer software,such as plane and stereo.At present,the results have been applied in many fields,such as topographic surveying,urban planning,disaster management and land comprehensive renovation.This paper mainly studies the digital terrain surveying and mapping technology based on UAV and its application in the management of land comprehensive renovation,the main work includes the following aspects:(1)Research on the principle and method of digital terrain mapping based on UAV.This paper studies the basic knowledge of digital terrain surveying based on UAV and the principle and method of UAV digital terrain surveying and mapping data,and analyzes and researches the digital terrain surveying and mapping technology based on UAV.(2)Digital terrain surveying and mapping process based on UAV.This paper discusses the implementation process and data production process of unmanned aerial vehicle digital terrain surveying and studies its results.(3)Application of digital terrain surveying and mapping results based on UAV.Based on the task of comprehensive management of land in Yongzhou Ningyuan County Zhonghe Town,the application process of unmanned aerial vehicle digital topographic surveying and mapping results in land comprehensive renovation management project is studied,and the actual achievement of the project is evaluated comprehensively.
