METHOD, AS WELL AS APPARATUS, DEVICE, SYSTEM AND DATA MEDIUM FOR OBTAINING AND CREATING TRAJECTORY OF SPACE-TIME MOVEMENT Russian patent published in 2025 - IPC G06T19/00 

FIELD: physics.

SUBSTANCE: present invention relates to a method, as well as an apparatus, a device, a system and a data medium for obtaining and creating a trajectory of space-time movement. Method includes: obtaining a first time series containing a plurality of sampling points, where the sampling points are the projection points of the reality display device; for any sampling point, setting a time window based on the sampling time of the current sampling point, finding the first sampling point and the last sampling point in the time window; taking a first position, which is a centre point of the reality display, corresponding to the current sampling point, as the centre of the circle, calculating the angular velocity between the first sampling point and the last sampling point and applying the current sampling point as the offset point if the angular velocity is greater than a predetermined threshold value of the angular velocity; executing said process with respect to a plurality of sampling points to obtain a second time series comprising a plurality of offset points; and trajectory mapping based on the second time series.

EFFECT: present invention can comprehensively, completely and systematically record information on time and space of movement of a human body in a virtual reality or mixed reality scene.
