The world’s largest aerial array mapping camera came out

Recently, a large format digital aerial camera undertaken by the 508 Institute of the Fifth Academy of Aerospace Science and Technology Group has completed the technical calibration flight and data processing in the sample stage. The camera function is normal, the image quality is good, and the mapping accuracy meets the highest scale accuracy requirements of the national standard. At present, the project has been transferred to the stage of application flight calibration, and the pilot production of application flight and image products will be carried out in the future. < / P > < p > the camera creatively adopts a new multi center parallel mapping imaging system, which breaks through the core technology of mapping and imaging of super large format construction under the limitation of imaging detector scale. At the same time, the project team has also overcome the key technology of large field of view and wide spectral range aspheric transmission lens alignment, to ensure the camera high speed, high efficiency, high quality and stable imaging. < / P > < p > in order to meet the requirements of the existing flight platform and realize the integrated design of multiple wide field of view lenses with limited aperture size, the technicians have completed more than 10 versions of design schemes; in order to improve the efficiency of big data forwarding, the designers put forward the processing scheme of high data rate fusion board forwarding, which not only meets the requirements of big data transmission, but also has In order to solve the problem of high-precision calibration in camera splicing imaging mode, designers boldly put forward a three-in-one three-dimensional calibration scheme of indoor test field, ground test field static and air dynamic, which has been fully verified by many flight tests. < / P > < p > in the application of the camera, the wide field of view and large base height ratio of the camera enable it to improve the operation efficiency by about 1.5 times compared with the typical similar products at home and abroad under the same working conditions of aerial photography, and can obtain higher mapping accuracy, effectively promoting the operation level of aerial photogrammetry. < / P > < p > in the application stage, the project will cover natural resources, land transportation, geophysical remote sensing and other fields, and the application area is distributed in Shanxi, Sichuan, Hunan and other provinces, with a total area of about 4000 square kilometers.
