Application Of Uav Aerial Survey Technology In Large Scale To Pographic Map Making

In recent decades,with the development of science and technology,unmanned aerial vehicle(UAV)technology has been developing rapidly.At the beginning,UAV technology has been used in military field.The combination of unmanned aerial vehicle(UAV)technology and aerial photogrammetry is a new and important direction in the field of aerial photography.The UAV aerial digital technology with its unique advantages,has become an effective complement and expand the technology of aerial photography,the flexible technology in the process of operation,short operation cycle,high production efficiency,low cost,quick access to information on the ground,landform monitoring,disaster assessment,crop survey.The establishment of digital cadastral survey,3D city has obvious advantages,has been widely concerned in the field of industry.The unmanned air vehicle using aerial technology as the research object to large scale mapping,introduces the theoretical basis and no specific steps in aerial photogrammetry in human and matters needing attention,combined with Lingbi County 1:1000 topographic map production project,the application of UAV aerial technology in actual operations further this,and the mapping results of the precision test,mainly has the following several aspects of research:(1)describes the structure of UAV and aerial photogrammetry during the operation of the main operation steps and theoretical basis,including the strip layout,control point measurement,empty three encryption,acquisition and editing within the industry,and based on the specific engineering example discusses the detail steps of empty three encryption.(2)Lingbi County 1:1000 large scale topographic map based on UAV aerial technology,specifically in the practical application of the operation are described in detail,and the inspection by the survey of high precision flat topography,the UAV operations meet the requirements of the standard conclusion.(3)summary of the UAV aerial technology in the actual operation of the advantages and disadvantages of several aspects of UAV mapping might affect the accuracy of analyses: its equipment,strip layout,space three encryption,acquisition and editing,and puts forward the methods of how to improve the operation requirements of technology and precision of UAV aerial operations...
