Method and system for tracking and displaying object trajectory

An object trajectory tracking and displaying system, comprising a trajectory tracking server and a distributed search server for a requesting terminal to access the trajectory tracking server and the distributed search server, wherein:

• each of the trajectory tracking server and the distributed search server comprises at least one processor and a storage and a communication component communicatively coupled to the at least one processor, and
• the storage stores instructions executable by the at least one processor, and a data channel is created through the communication component when the instructions are executed by the at least one processor to cause the at least one processor to execute the instructions, wherein the instructions comprise:
• instructions for creating a mapping relationship database of image features and WIFI information for objects in a distributed search server, wherein each WIFI information comprises position information;
• instructions for receiving a trajectory query request for a monitored object;
• instructions for searching the mapping relationship database of image features and WIFI information for objects according to an image feature of the monitored object to produce a WIFI information set, and producing a corresponding position information set based on the WIFI information set;
• and
• instructions for generating real-time trajectory information of the monitored object based on the position information set.
