Embodiment Construction

[0056] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the following will further describe the embodiments of the present application in detail in conjunction with the accompanying drawings.

[0057] Before explaining the embodiment of the present application in detail, the application scenario involved in the embodiment of the present application is explained first.

[0058]At present, in indoor monitoring scenarios, tilted cameras are usually deployed on the walls around the indoor area, but tilted cameras are prone to occlusion due to viewing angles, resulting in unavailable features of the collected images and prone to problems such as tracking interruption. Moreover, the positioning accuracy of the tilted camera tracking trajectory is poor, so the accuracy of cross-camera association will be relatively low.

[0059] In order to achieve higher camera correlation accuracy, vertical cameras can also be u...

Abstract

The embodiment of the invention discloses a method and a device for determining a motion trail and a computer storage medium, and belongs to the field of monitoring. The method comprises the followingsteps: determining the motion trails of a first motion trail and a second motion trail in the same time period to obtain a first overlapping trail and a second overlapping trail, and determining thesimilarity between the first overlapping trail and the second overlapping trail; and if the similarity between the first overlapping trail and the second overlapping trail is greater than a similaritythreshold, determining that the first motion trail and the second motion trail are motion trails of the same object. In the embodiment of the invention, it is judged whether the two motion trails aremotion trails of the same object or not based on the spatio-temporal overlapped parts of the two motion trails; and whether the two motion trails are the motion trails of the same object or not is judged according to the image features of the objects corresponding to the different motion trails, so that the situation of misjudgment according to the image features can be avoided, and the monitoring accuracy is improved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of monitoring, and in particular to a method, device and computer storage medium for determining a motion trajectory. Background technique [0002] In order to realize accurate monitoring of a large-scale area, multiple cameras are deployed in the area, and the multiple cameras are respectively responsible for monitoring a part of the area, and the monitoring range of each camera is different. In this scenario, it is necessary to obtain the motion trajectory tracked by each camera for the same object, and associate the motion trajectory tracked by each camera for the same object, so as to realize the monitoring of the object in the area. [0003] In related technologies, any camera can track the movement trajectories of all objects within the corresponding monitoring range, and at the same time acquire the image features of each object. In this way, for the two objects tracked by...
