Embodiment 1
[0055] Embodiment one: if figure 1 The method for generating summary information of the shown motion trajectory, which is completed in the server, includes:
[0056] Step 1: Receive the position sequence sequence of the person to be monitored and generate the movement track of the person to be monitored. The position sequence sequence includes the ID, time and position ID of the person to be monitored.
[0057] Time-series data is obtained by collecting individual positions according to time intervals and fixed time intervals, and its format is as follows:
[0058] [Personnel ID to be monitored, time, location ID];
[0059] Among them, the ID of the person to be monitored and the ID of the location represent the unique identification of the person to be monitored and its location, which can be represented by codes, for example: the ID of the person to be monitored is: 001, 002, 003; the location ID can be E116° 23'N39°54', indicating that the location is 116°23' east latitud...

The invention discloses a method and system for generating summary information of a movement trajectory. The method is completed in a server, including receiving the position sequence sequence of the person to be monitored and generating the movement trajectory of the person to be monitored, and the position sequence sequence includes the sequence sequence of the person to be monitored. ID, time and location ID; according to the time value in the location time series and the characteristic information of each place in each time period in the social environment, the attribute of the place at each location ID is obtained; the movement track of the person to be monitored is divided into at least one sub-track, Set the place at the corresponding position ID at both ends of each sub-track as a node, and store the time information and trend direction corresponding to the corresponding node in the node database; retrieve the time information and trend direction of each node in the node database, generate a track tree and Store in the track tree database; add logical connectives between each node of the track tree to generate summary information of the movement track of the person to be monitored.
Description
technical field [0001] The invention belongs to the field of personnel monitoring, and in particular relates to a method and system for generating summary information of motion tracks. Background technique [0002] Trajectory refers to all the paths that individuals move through to meet their needs in the objective space. It is an objective manifestation of individual behavior. Trajectory management is to effectively analyze the behavior path of individuals, fully mine the effective data and abnormal data in the trajectory, so as to find problems in time and correct them, so as to ensure the good living conditions of individuals and groups, and thus produce good management effects . Abnormal living conditions are very harmful to individuals and society. If the abnormality cannot be discovered in time, it is easy to go astray and become a hidden danger to the family or society. [0003] The existing individual trajectory monitoring has poor continuity of position and time ...
