Abstract

The invention discloses a method and device for generating frequent location trajectories based on moving targets, which relates to the field of positioning technology, and the main purpose is to solve the problem of massive location data with different precision, and it is impossible to determine the accurate and frequently occurring target trajectories. The problem with the target location trajectory. The technical solution includes: obtaining the position information of the moving target; performing the associated operation between the track segments corresponding to the position information according to the track segment correlation function; dividing the position information after the associated operation according to the preset grid division method; The established motion state filter and the preset feature point extraction algorithm extract the feature points of the position information after grid division to obtain the resampling trajectory; according to the time attribute, position attribute, orientation attribute and preset space clustering algorithm, the The sub-trajectory form clusters the resampled trajectories after extracting feature points; scans the clustered sub-trajectories and generates frequent position trajectories.

Description

technical field [0001] The present invention relates to the field of positioning technology, in particular to a method and device for generating frequent position trajectories based on moving objects. Background technique [0002] In order to locate and track moving targets, technologies such as location service system GPS, passive reconnaissance and positioning system, and satellite-borne airborne remote sensing system are widely used. Among them, the trajectory of moving targets can be obtained by real-time positioning of the moving targets . [0003] At present, it is possible to locate and track the position of a moving target for a long time to obtain a cumulative position trajectory. This long-term positioning and tracking requires high-precision positioning data, such as the data recorded by the GPS system, but when the obtained position When the data accuracy is low or the location accuracy is unstable, a large amount of location data with different accuracy will be...
