Problems solved by technology

However, when a special situation occurs and the target object needs to be tracked, in the prior art, the monitoring video is generally manually checked. This method not only cannot find the target object in the monitoring video in time, but also tends to be missed or missed. In the case of misreading, the accuracy and efficiency are relatively low

Embodiment 1

[0053] see figure 1 As shown, it is a schematic flowchart of a method for determining a movement trajectory provided in the embodiment of the present application, including the following steps:

[0054] Step 101. Obtain surveillance video uploaded by at least one camera and determine the biological characteristics of objects appearing in each surveillance video.

[0055] Considering that the video transmission process may take a lot of time, before obtaining the surveillance video uploaded by at least one camera, a request for obtaining the surveillance video input by the user may also be received, so as to prevent each camera from uploading the surveillance video. Wherein, the request for obtaining the surveillance video input by the user may include identification information of the surveillance video requested to be obtained.

[0056] In a possible implementation manner, the camera can be configured with a feature extraction device with a biometric feature extraction funct...

Embodiment 2

[0086] The embodiment of the present application also provides a mobile trajectory determination device, see image 3 As shown, it is a schematic diagram of the structure of a device for determining a movement trajectory provided by the embodiment of the present application, including an acquisition module 301, a first determination module 302, a second determination module 303, a search module 304, and a labeling module 305, wherein the search Module 304 includes a processing unit 3041, a comparison unit 3042, and a recording unit 3043, specifically:

[0087] An acquisition module 301, configured to acquire surveillance video uploaded by at least one camera and determine the biological characteristics of objects appearing in each surveillance video;

[0088] The first determination module 302 is configured to determine the selected target surveillance video, the target surveillance object selected in the target surveillance video, and the target camera uploading the target su...

Embodiment 3

[0107] Based on the same technical idea, an embodiment of the present application also provides an electronic device. refer to Figure 4 As shown, it is a schematic structural diagram of an electronic device 400 provided in the embodiment of the present application, including a processor 401 , a memory 402 , and a bus 403 . Among them, the memory 402 is used to store execution instructions, including a memory 4021 and an external memory 4022; the memory 4021 here is also called an internal memory, and is used to temporarily store calculation data in the processor 401 and exchange data with an external memory 4022 such as a hard disk. The processor 401 exchanges data with the external memory 4022 through the memory 4021. When the electronic device 400 is running, the processor 401 communicates with the memory 402 through the bus 403, so that the processor 401 executes the following instructions:

[0108] Obtaining surveillance video uploaded by at least one camera and determin...

Abstract

The invention provides a moving track determining method and device. The moving track determining method comprises the following steps: acquiring a monitoring video uploaded by at least one camera anddetermining biological characteristics of an object appearing in each monitoring video; determining a selected target monitoring video, and uploading a selected target monitoring object in the targetmonitoring video to a target camera of the target monitoring video; determining target biological characteristics of the target monitoring object, and determining a target moment at which the targetmonitoring object disappears in the target monitoring video; based on the target time and the target biological characteristics, searching for cameras, except the target camera, with the target monitoring object; and based on the position information of the target camera and the target moment recorded in each searching process, marking the position information of the target monitoring object on the map, and determining the marking result as the moving track of the target monitoring object. Through the moving track determining method, the target monitoring object searching efficiency and accuracy can be improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method and device for determining a movement trajectory. Background technique [0002] With the popularization of monitoring technology, more and more places can realize monitoring without dead ends. However, when a special situation occurs and the target object needs to be tracked, in the prior art, the monitoring video is generally manually checked. This method not only cannot find the target object in the monitoring video in time, but also tends to be missed or missed. In the case of misreading, the accuracy and efficiency are relatively low. Contents of the invention [0003] In view of this, the purpose of the present application is to provide a method and device for determining a movement track, so as to improve the accuracy and efficiency of finding a target surveillance object. [0004] In the first aspect, the embodiment of the present application provi...
