Rapid Modeling Technology Of UAV Photogrammetric And Its Engineering Application

Photogrammetric is a subject of taking pictures on the measured object,and then use software to deal with the photograph,and finally confirmed by the object's position,size,shape,nature and the relationship.Now as the small drones in the field of photogrammetry applied more and more get the attention of people,uav photogrammetry technology began to be widely studied.In this paper,based on the content of the uav photogrammetry technology,this paper first introduces the concept of uav photogrammetry and basic principle.Then depends on the beipanjiang river bridge project in detail uav photogrammetry rapid modeling technology of concrete operation steps and matters needing attention.Mainly includes two large pieces of content data gathering and processing in the industry.Data collection content have route planning,upload the routes and so on.Processing by photoscan software platform in the industry will get the pictures of unmanned aerial vehicle(uav)to collect information and coordinate data modeling processing,get the initial 3d models.And then through and edit on3 dmax perfect model.Finally,this article use uav photogrammetry rapid modeling technology to the study of deformation monitoring on the water conservancy project.The research of this paper is not only the principle of photogrammetry and modeling technology for unmanned aerial vehicle and expounds the concrete operation steps,more the application of this technology provides an intuitive and realistic case.With the development of the technology,I believe small uav photogrammetry system application prospect will be broader.The results will greatly expand the application field.Such as archaeological survey,topography and regional planning,environmental monitoring,such as mud-rock flow,earthquake,regional survey,such as Bridges,DAMS,and even applied to military war and safety accidents.
