Problems solved by technology

Due to the limitation of the shooting angle, when there are many pedestrians or the distance between pedestrians is close, mutual occlusion is likely to occur in the video
In related pedestrian tracking methods, it can be based on traditional filters, such as KFPPK (Kalman filter and the probability product kernel) algorithm, through algorithm estimation to deal with mild occlusion problems; there is also a method based on A robust multi-target detection and tracking algorithm based on Kalman filtering, which uses pixel-level differences and aspect ratios for occlusion judgment; When non-pedestrian factors interfere, the occlusion processing effect of the above methods is poor, which leads to low pedestrian tracking accuracy

Embodiment 1

[0027] First, refer to figure 1 An example electronic system 100 for implementing the object tracking method, device and system of the embodiments of the present invention will be described.

[0028] Such as figure 1 A schematic structural diagram of an electronic system is shown, the electronic system 100 includes one or more processing devices 102, one or more storage devices 104, input devices 106, output devices 108 and one or more image acquisition devices 110, these components The interconnections are via bus system 112 and / or other forms of connection mechanisms (not shown). It should be noted that figure 1 The components and structures of the electronic system 100 shown are exemplary rather than limiting, and the electronic system may also have other components and structures as required.

[0029] The processing device 102 may be a gateway, or an intelligent terminal, or a device including a central processing unit (CPU) or other forms of processing units with data ...

Embodiment 2

[0036] This embodiment provides a target tracking method, which is executed by the processing device in the above-mentioned electronic system; the processing device may be any device or chip with data processing capability. The processing device can independently process the received information, or can be connected with a server to jointly analyze and process the information, and upload the processing results to the cloud.

[0037] Such as figure 2 As shown, the target tracking method includes the following steps:

[0038] Step S202, acquiring the current frame image;

[0039] For a piece of video data, when performing target tracking on it, the target object can be detected and identified in chronological order starting from the first frame of the video data; multiple frames of images are identified as the same target Objects of objects are identified by the same serial number or symbol to track the target object. In the actual tracking process, each frame image in the a...

Embodiment 3

[0059] This embodiment provides another target tracking method, which is implemented on the basis of the above-mentioned embodiments; in this method, the target tracking method is further described, especially the specified target that is occluded and the target that is occluded by the specified target. The tracking method of the occluded target; such as image 3 As shown, the method includes the following steps:

[0060] Step S302, acquiring the current frame image;

[0061] Step S304, detecting the target object in the current frame image through the first network model;

[0062] The first network model can detect the target object through face detection or human figure detection; usually, the detection data obtained by face detection usually includes a human face or head, and the detection data obtained by human shape detection usually includes the whole human body. It can be seen from the description of the above embodiment that target tracking needs to be realized based...

Abstract

The present invention provides a target tracking method, device and system; wherein, the method includes: detecting a target object in a current frame image through a detection model, and judging whether the target object is a designated target; Specify the tracking target that matches the specified target in the frame image; if there are multiple matching tracking targets, the specified target is determined from the multiple tracking targets according to the relative positions of the detection data of the multiple tracking targets; according to the multiple tracking targets Among them, the position of the tracking targets other than the designated target in the designated frame image, the position of the tracking targets other than the designated target in the current frame image is estimated, and the occluded target is determined from the tracking targets other than the designated target according to the estimation result. The invention can realize the tracking of the unoccluded target object and the occluded object, reduce the occurrence probability of tracking loss, and improve the accuracy of target tracking.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a target tracking method, device and system. Background technique [0002] In the field of surveillance, tracking pedestrians is of great value. Due to the limitation of shooting angle, when there are many pedestrians or the distance between pedestrians is close, mutual occlusion is easy to occur in the video. In related pedestrian tracking methods, it can be based on traditional filters, such as KFPPK (Kalman filter and the probability product kernel) algorithm, through algorithm estimation to deal with mild occlusion problems; there is also a method based on A robust multi-target detection and tracking algorithm based on Kalman filtering, which uses pixel-level differences and aspect ratios for occlusion judgment; When non-pedestrian factors interfere, the occlusion processing effect of the above methods is poor, which leads to low pedestrian tracking accurac...
