Abstract
The present application relates to a method, apparatus, device, system and storage medium for collecting spatiotemporal behaviors and generating a spatiotemporal behavior track. The method includes: obtaining a first time series containing a plurality of sampling points; taking one sampling point as a current sampling point; setting a window time, and finding a first sampling point and a last sampling point within the window time; taking a first position as a center of a circle, which is a center point of the reality display device corresponding to the current sampling point, and calculating an angular speed between the first sampling point and the last sampling point; if the angular speed is greater than a preset angular speed threshold, taking the current sampling point as a displacement point; processing the plurality of sampling points as described above to obtain a second time series; drawing a moving track map.
