METHOD AND SYSTEM FOR REVERSE OPTICAL TRACKING OF A MOBILE OBJECT Russian patent published in 2019 - IPC G06T7/70 

FIELD: information technology.

SUBSTANCE: invention relates to moving object tracking method and system and can be used in virtual or augmented reality systems. Technical result is achieved by the fact that the tracking method includes a step of automatic adjustment of the tracking zone, on which unique combinations of elementary optical patterns are detected and recorded, and a step of tracking the change in the position and/or orientation of the mobile object, on which unique combinations of elementary optical patterns are detected and compared with those recorded when tuning the tracking system zone. Moving object tracking system comprises at least one tracker arranged on the movable object and having an optical sensor; at least one marker strip containing active markers forming elementary optical patterns on the image obtained from the optical sensor; and central data processing device.

EFFECT: automatic adjustment of the tracking zone during reverse optical or optical-inertial tracking of the mobile object using a tracker mounted on the mobile object and comprising an optical sensor and an inertial sensor.
