Method and system for obtaining trajectory pattern of route

A system for obtaining a trajectory pattern of a route, comprising:

• a point set obtaining unit configured to obtain a set of points associated with the route, the set of points being obtained by at least one entity travelling along the route;
• a coverage determining unit configured to identify a current coverage area in a plurality of coverage areas in a search range comprising an initial search area covering a part of points in the set of points;
• and
• a global connecting unit configured to
• determine whether the search range includes a blind area indicative of a location sensing gap that intervenes the current search area and a successive search area such that the current search area is unconnected with the successive search area;
• determine a main direction of the current coverage area;
• expand the search range to an expanded search range in response to the successive coverage area being not found within the search area, wherein the expanded search range comprises a search distance exceeding a search distance of the initial search area, and the expanded search range skips the sensing gap;
• connect the coverage area with the successive search area based on the main direction of the current coverage area to obtain the trajectory pattern related to the route, the main direction representing a forward direction of the trajectory pattern;
• and;
• a display operatively connected to an input/output interface, the display configured to output, via the input/output interface, the updated route comprising the forward direction of the trajectory pattern.
