Trajectory information processing device and method

Abstract

The invention provides a trajectory information processing device and method. By using the trajectory information processing device, different position points in moving trajectories of one or more mobile terminals are matched, the position points with matched positions are determined, and a trajectory map is synthesized by using the matched position points and trajectory information. The trajectory information processing device can be used for automatically generating an electronic map and further analyzing a foot passenger distribution characteristic, a user behavior characteristic and other factors in a region so as to provide analytical data with reference values and the like for business management activities. In addition, by using the trajectory information processing device and method, the synthesized trajectory map can also be used for navigation service, the operations of artificially modeling the environment or inputting map data in advance are not needed, the labor and time consumption caused by artificially modeling the environment or inputting the map data in advance in the existing navigation technology is avoided, the construction cost of the electronic map is reduced, and the efficiency and accuracy of the navigation service are increased; and the trajectory information processing device and method have favorable real-time performance and expandability.
