Abstract

An embodiment of the present invention provides a trajectory data reporting method and a moving trajectory restoration method. The trajectory data reporting method includes: taking the first data point in the original trajectory data as the initial data point, and judging the nth data point after the initial data point Whether the data point meets the preset conditions; if the nth data point meets at least one of the preset conditions, report the nth data point. The trajectory data reporting method and the moving trajectory restoration method provided by the embodiments of the present invention are based on the virtual road width and boundary in the three-dimensional space, the end-to-end line segment composed of N tangents, the connection point is the trajectory data collection point, As well as the well-formed linear trajectory formed by these points, the algorithm makes the trajectory more intuitive and clearly restores the actual driving route without greatly increasing the amount of reported data.

Description

technical field [0001] The invention relates to the technical field of mobile positioning, in particular to a method for reporting track data and a method for restoring a moving track. Background technique [0002] Mobile positioning refers to the technology or service that obtains the location information (latitude and longitude coordinates) of a moving object through a specific positioning technology, and marks the location of the positioned object on an electronic map. The moving track of the moving object is obtained by connecting the position points in multiple electronic maps into a line according to the sequence of time. [0003] In the prior art, most of the vehicle positioning is through the satellite positioning module, for example, the real-time trajectory data is obtained through the GPS positioning module. It is reported to the background server for storage, and after the event, supervisors can retrieve its driving track data at any time to restore the vehicle'...
