- Abstract
In the article, a variant of solving the problem of aerial photograph efficiency delivery from the aircraft without loss of its reliability are discussed. It is proved that information technologies at the level of information representation on a digital aerial photo do not guarantee the delivery of an aerial photo without risks, to lose its authenticity. The variant of reducing the information aerial photo coming from the aircraft is considered, without loss of its efficiency and authenticity.The classification of aerial photographs depending on their importance for facilitating the work of the decryptor is considered. The variant of realization of deciphering coding technology of an aerial photo is proved. The reasons for the risks of disrupting tasks for deciphering aerial survey objects are justified. A perspective technological concept of an effective syntactic description of aerial photograph sufficiently informative segments elements that take into account the characteristics of the discrete cosine transform is proposed. The direction of reduction of aerial photos information redundancy with preservation of key information is offered. The highly informative aerial photographs informative intensity reducing technology was created. This technology is based on two conceptual components: the mechanism of diagonal reading of the coefficients of the highly informative image segment transformant and a mechanism based on two-graded uneven positional coding with a dynamic basis update. This provides the reduction of the information intensity of aerial photographs and the restoration of segments of aerial photographs without losing key information to deciphering. In turn, the decreasing of the aerial photographs information intensity will positively affect the throughput of onboard data transmission channels, which will lead to increasing of aerial photograph speed delivery. The developed method work description for reducing the information intensity of highly informative segments of an aerial photograph is given. The results of the research can be used for design and production of perspective digital scanners.
