Method, apparatus, device, system and storage medium for collecting spatiotemporal behaviors and generating a spatiotemporal behavior track

An apparatus for collecting spatiotemporal behaviors and generating a spatiotemporal behavior track, comprising:

• a sampling point obtaining module, configured for obtaining a first time series containing a plurality of sampling points, wherein the plurality of sampling points are projection points of a reality display device;
• a displacement point obtaining module, configured for selecting any one of the plurality of sampling points as a current sampling point;
• setting a window time based on a sampling time of the current sampling point, and finding a first sampling point and a last sampling point within the window time, wherein a middle time of the window time is the sampling time of the current sampling point, and the window time comprises sampling times corresponding to at least three sampling points of the plurality of sampling points;
• connecting a center point of the reality display device with the first sampling point and the last sampling point with straight lines respectively to form a first included angle;
• calculating an angular speed between the first sampling point and the last sampling point according to the first included angle and a time interval between the first sampling point and the last sampling point;
• when the angular speed is greater than a preset angular speed threshold, taking the current sampling point as a displacement point;
• and performing the above process on each of others of the plurality of sampling points to obtain a second time series containing a plurality of displacement points;
• and
• a drawing module, configured for drawing a moving track map based on the second time series.
