Quality Requirements for First Person View Unmanned Systems Control Service

Unmanned systems' first-person view control requires transmitting the video stream from the unmanned system to its operator. The quality of the transmitted video stream directly affects the external pilot's assessment of the current flight situation and the formation of appropriate and timely control commands. The paper investigates the dependence of the unmanned system's operational objective achievement probability on the objective video stream quality metrics (SSIM, PSNR). Relevance of this work is based on the necessity to determine the unmanned system FPV control video coding system parameters depending on the specified unmanned system’s operational objective achievement probability. Methods used. When processing the results of natural experiments, methods of statistical analysis, experimental design theory and probability theory were used. Results. Quantitative values of video stream quality metrics requirements are justified when using standard video codecs for a given operational objective achievement probability in unmanned systems FPV control for various purposes. Novelty of the results is that the requirements for the transmitted video stream quality metrics are determined not by experts, but by experiments based on the analysis of the transmitted video stream quality, which allowed to develop the unmanned system control that achieved its operational goals. Practical significance. The required values of FPV video stream quality metrics have been determined, at which FPV control is possible with a given unmanned system’s operational objective achievement probability.
