Research on the computer aided design of UAV aerial photography scheme

With the development of science and technology,UAV aerial photogrammetry has gradually become an important means of modern surveying and mapping technology with the advantages of high timeliness,flexibility and high accuracy of data acquisition,playing an increasingly important role in the field of Surveying and mapping.However,at present,the design of UAV aerial photography scheme mainly relies on manual work,which is not assisted by system equipment.It needs a lot of work and is difficult to meet the specific work requirements of UAV aerial photography.In view of the problems,this paper puts forward a technical method of using computer-aided design for aerial photogrammetry scheme of UAV,and develops a scheme design book according to the design of navigation area and relevant parameters before the UAV flies.It is convenient for the staff to verify the feasibility and safety of UAV flight operation in theory,improve the automation process of aerial photography scheme design,improve the work efficiency,and provide technical and safety guarantee for carrying out photogrammetry.
