Experimental Study On DOM Production Of UAV Image Based On INPHO

As has been developed rapidly in recent years a new type of aerial photographic survey technology,low altitude unmanned remote sensing for the high efficiency and real-time performance is strong,the maneuverability is strong,work fine,low cost,and can at any time for small scale aerial and aerial remote sensing image acquisition difficult place to quickly get characteristics such as high resolution image,to make it in the national census,geographical annotation,emergency early warning,disaster evaluation and post-disaster reconstruction and so on has the great advantage,more and more been used in various industries.But it compared with traditional aerial with aerial platform attitude stability is poorer,pictures like picture,photo Angle is too large,too small adverse factors such as the image distortion is larger.These factors bring a lot of difficulties to the image processing of drones,and also pose new challenges for the construction of digital photogrammetric systems.This paper mainly discusses the experimental work of remote sensing image processing.(1)analysis of the composition and features of the uav aerial system,studies the influence factors of uav aerial photography as,highlight the aviation image of the unmanned aerial vehicle(uav)to obtain advantage in the production of surveying and mapping.(2)study using unmanned aerial vehicle(uav)for aerial photography as a key technology with orthogonal projection as figure production process,including the image distortion processing,analytical aerial triangulation,and light and color,is correct,key technology such as precision comparison has carried on the key analysis and research.In this paper,the paper makes a key analysis of the problems in the two areas in the two areas of the plain mountain area.And experiment of three parts in the design based on INPHO and VirtuoZo aerial system of plain area measurement DOM generates experiment,has carried on the analysis and comparison of two kinds of software to generate a DOM precision illustrates INPHO image processing system for different terrain adaptation degree of remote sensing data processing and the advantages compared with other software.
