The paper presents the stages of frame processing using OpenCV for subsequent gesture recognition. At the beginning, a brief overview of an existing solution is given. Each step of the analysis method used is described. An algorithm for reducing ”convexity defects” is proposed. Tests were performed using a printed gesture on a piece of paper and using a black glove. The results of the testing are presented, and the problems that need to be overcome are described.

This work shows the main requirements for a system for an unmanned landing of a flying vehicle using a pseudo-conical scanning method. The research work focuses on the system sensor - a circularly polarized phased antenna array with pseudo-conical scanning, for locating, intercepting and controlling the detected object - UAV. A functional model of the considered antenna system, with nine beam states, is created. Simulated and measured results are presented.
