Aerospace Instrument-Making Annotation << Back Optimization of the UAV Flight Altitude Selection and Stereo Camera Pair Indicators to Reduce the Smudge of the Generated Remote Sensing Images Alieva G.V., Huseynov O.A. The article is devoted to the issues of determining the fl ight altitude of a reconnaissance UAV, taking into account the appearance of smudge in the images generated by the stereo pair. Two optimization problems have been formed and solved: (1) determining the optimal dependence of altitude on fl ight speed at which the total image size reaches a minimum; (2) determination of the optimal dependence of the operating indicator b on the height at which the average integral value of the lubricant reaches a minimum. These tasks were solved using the method of unconditional variational optimization. The conditions under which the total image size reaches a minimum are investigated. The optimal operating ratios have been determined, under which it is possible to improve the qualitative and quantitative indicators of UAV-based search and detection systems.
