DGPS/IMU Auxiliary Aerial Photography Aerial Photo Processing Method

With the rapid development of city construction, as an effect complement to the satelliteremote sensing and conventional aerial remote sensing, UAV aerial photography method providedecision-making for city development and plan. According to the characteristics of the UAVaerial photography, clarified the advantages and disadvantages of the aerial photography, UAVaerial photography system structure, the UAV aerial data pre-processing principle and process.Through the study of DGPS/IMU auxiliary aerial photography principle select the INPHO seriessoftware andifferent method processing aerial photo in different conditions, fast to get a certainarea of DOM meeting certain requirements. With the development of aerial survey system andthe computer vision, brought convenience to the UAV aerial triangulation implementation, butprocessing UAV aerial technology are badly needed. This paper uses INPHO software produceDOM combined with the Guangdong Yang image data and carried out in-depth study andresearch, introduced qualified digital orthophoto procedure using INPHO software, discussedINPHO parameter setting method,DGPS/IMU auxiliary aerial photography technology,aerialphotography inside and outside procedure and the method of INPHO series software processingUAV data, provide necessary help for DGPS/IMU auxiliary aerial photography and within thepages of data processing.Through the study of the aerial data processing principle and practice of production process,this paper has solved the INPHO series software processing aerial data encountered in matchingfailure problem, used POS data involved in the computation, completed the connection pointextraction process, produced products meeting the requirement of the digital DOM product. Withthe technology of GPS and inertial navigation system development,GPS assisted aerialphotography technology development, DGPS/IMU combination brings revolutionary change foraerial photography. This paper has been introduced the principle of DGPS/IMU assisted aerialphotography. Solved the error and correction methods of DGPS/IMU auxiliary aerialphotography, the UAV Aerial Photogrammetry data processing method of experiment, summedDGPS/IMU auxiliary of different methods of aerial photography on the results of the air aerialtriangulation and the DOM attainable accuracy.In order to get a high precision of velocity, position and attitude, DGPS/IMU combinedaerial photography quality improves, save a lot of money and economic losses.Aerial photography technology provides intuitively true digital imaging products in our life, to build abeautiful home and provides an effective means of aerial surveying technology, new ideascontinue to emerge, and new problems continue to overcome, more and more image of the realword will appear in our life.
