A method and device for determining a motion trajectory

Abstract

The embodiment of the invention discloses a method and apparatus for determining a motion locus. The method comprises: a target picture containing a target person is selected from a picture library, wherein the picture library is used for storing pictures collected by all collection points and the collection points are used for collecting address information of pictures and / or equipment carried by people; according to the collection point corresponding to the target picture, at least two target collection points are determined and a first preset period of time where collection time corresponding to the target picture is located is determined as a target period of time; at least one piece of address information that is collected by the part of or all of the at least two target collection points during the target period of time is obtained; and a motion locus of the at least one piece of address information is obtained, the obtained motion locus is associated with the target person, and thus the motion locus of the target person is determined. Therefore, the motion locus of one person can be determined accurately and the accuracy of personnel tracking is improved.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method and device for determining a motion trajectory. Background technique [0002] At present, the security monitoring system is often used to track personnel. When tracking a person, it is necessary to first determine the movement track of the person, and track the person according to the movement track, so that the tracking efficiency can be effectively improved. [0003] In the prior art, the pictures collected by the collection points are usually used to determine the movement trajectory, which specifically includes: comparing the pictures collected by each picture collection point with the query pictures containing the target person, obtaining pictures with a similarity greater than a preset threshold, and comparing the pictures acquired Corresponding collection points are connected, and the track corresponding to the connecting line is determined as the movemen...

AI Technical Summary

Problems solved by technology

However, in the security monitoring system, the picture quality is affected by weather conditions (such as: sunny, rainy, foggy, snowy, strong wind, sandstorm), lighting conditions (such as: forward light, backlight, strong light, rain reflection, shadow), Influenced by factors such as video scenes (such as indoors and outdoors), it is difficult to obtain high-quality pictures

[0005] Based on the above reasons, it is difficult to accurately determine the movement trajectory of the person using the pictures collected by the collection point. Therefore, the accuracy of tracking the person is very low
