Embodiment Construction

[0076] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0077] figure 1 It is a flow chart of a method for expressing a motion track according to an exemplary embodiment. Such as figure 1 As shown, the motion trajectory representation method may include the following steps:

[0078] In step 102, k pieces of position data corresponding to the movement trajectory of the target object are acquired, where k is a positive integer.

[0079] I...

Abstract

The present disclosure relates to a motion trajectory representation method and device, and belongs to the technical field of data processing. The method includes: acquiring k position data corresponding to the motion track of the target object; determining the access situation of the motion track to preset n hotspot areas according to the k position data, and the hotspot area is calculated according to several historical motion tracks The obtained geographical area whose visit popularity is higher than the preset threshold; determines the trajectory feature vector corresponding to the movement trajectory according to the access situation, and the trajectory feature vector is used to represent the characteristics of the movement trajectory. This disclosure solves the problem that the large amount of data brought by directly using position data to represent the motion trajectory is not conducive to the calculation and processing of the subsequent analysis of the motion trajectory; In order to simplify the representation, the effect of data dimensionality reduction is achieved, and it is convenient for the subsequent analysis and calculation of the motion trajectory.

Description

technical field [0001] The present disclosure relates to the technical field of data processing, and in particular to a method and device for expressing a motion track. Background technique [0002] The trajectory of an object such as a person, vehicle or other object is usually represented by a set of position data obtained during the movement. [0003] Taking cycling as an example by a user, the user may carry a locator with a positioning function, such as a GPS (Global Positioning System, Global Positioning System) locator. During the ride, the locator collects the user's location data at predetermined time intervals. The user's movement trajectory during the entire riding process can be represented by a collection of all location data collected during the riding process. For example, if the locator collects location data every 3 seconds, the user's movement trajectory within one hour can be represented by more than 1,000 pieces of location data collected within the hou...
