Among them optical methods can perform an important role in a precise definition of drones' coordinates, their tracking and recognition. The paper is devoted to the primary signal processing in the passive optical system with two channels of video observation and photosensitive matrices. The considered configuration of the optical system allows estimate a distance from a drone and realize its angle tracking on the base of measuring linear parallaxes of drones light images projected onto matrices. Experimental results include corrections of lens distortions.enangle trackingDJI Phantommotion detectionquadcopterrange estimationstereo video observationUAVvideo streamArticle
