- To reduce the load on the operator of an unmanned aerial vehicle (UAV) during long search and rescue, and monitoring missions, the concept of an automatic system is proposed, which directly on board performs a prelimi-nary analysis of images received from a high-resolution navigation video camera, determines areas of interest, and sets the position of an additional camera with a reduced viewing angle to scale the image of the selected area. This allows the operator to speed up the final decision and reduces the re-sponse time to the detection, identification of an object, as well as to the preparation of a mission report. To develop a technical system that will be able to solve the tasks, a complex hierarchical model is considered, consist-ing of three components: a software system for image pre-processing and analysis, an electromechanical camera positioning system, and a higher-level human-machine complex. It is determined that the model of the first com-ponent should be based on the use of a deep learning artificial neural net-work using inference trees. The Simulink model of the positioning system contains a controller that improves the dynamics of two interconnected elec-tric drives by using three control loops in each of them. The features of in-formation perception by the operator of the UAV control complex are ana-lysed and the need to consider the effect of global precedence is noted. The results of the simulation of the electromechanical link are presented and the complexes of further research are outlined.

- To reduce the load on the UAV operator during long-term search and rescue missions, an on-board automatic system is considered that generates control signals for positioning an additional video camera with a narrow field of view. The requirements for the system of automatic detection of the area of interest are defined. Various methods for detecting objects in images are considered, analyzed and compared. Software and hardware tools are discussed, which are advisable to use in the preparation and conduct of experimental studies.

- Carrying out long-term search and rescue missions, intelligence, surveillance and reconnaissance, which are carried out with the help of unmanned aerial vehicles (UAVs), overload the operator and reduce the effectiveness of solving the assigned tasks, up to the point of making their implementation impossible. The paper proposes the concept of increasing the speed of the human-machine system based on information obtained from images transmitted in real time by video cameras installed on a platform moving relative to the UAV, by mean of the intelligent control system of this platform.Thus, the image from the main video camera with a wide viewing angle is divided into rectangular sections (zones), the size of which is determined by the viewing angle (zoom) necessary for the operator to make the final decision. The software system of the lower level, evaluating the video frame, determines and marks the areas in which the object of interest may be present. For the zone where the probability of the presence of the candidate object is the greatest, the focal length is increased and focusing (ie, zooming the image), as well as the positioning of the main camera. In another variant, a separate spot camera with a reduced and fixed field of view is aimed at the yaw and pitch angles, which requires that this camera be directly suspended on a gyro-stabilized platform, where a block of other sensors is installed, including the main video camera.An example of modeling the electric drive of a spot camera by the yaw angle is given and further steps are determined for the development of subsystems of three levels: software (recognition), hardware (scaling and positioning), human-machine (coordination of information flows). To improve the dynamic characteristics in comparison with the basic proportional-integral laws, it is proposed to use quasi-optimal algorithms for regulating electric drives.
