Embodiment Construction

[0034] This embodiment includes a video target tracking method, referring to figure 1 , including the following steps:

[0035] S1. Intercepting picture frames from the video captured by the camera; the camera is driven by the pan / tilt to move;

[0036] S2. Using the mean shift algorithm and the Kalman filter algorithm to perform target recognition on the picture frame;

[0037] S3. Performing a weighted average on the recognition result of the mean shift algorithm and the recognition result of the Kalman filter algorithm;

[0038] S4. Determine the position of the target in the picture frame according to the weighted average result;

[0039] S5. Control the pan-tilt to drive the camera to move, so that the target is located in the central area of ​​the picture frame.

[0040] The camera described in this embodiment is driven by a pan / tilt, and can perform movements such as translation and rotation to adjust the field of view or shooting range of the camera, and the camera ...

Abstract

The invention discloses a video target tracking method, system, device and storage medium. The method includes intercepting a picture frame from a video shot by a camera, and using a mean shift algorithm and a Kalman filtering algorithm to target the picture frame respectively. Recognition, performing weighted average on the recognition result of the mean shift algorithm and the recognition result of the Kalman filter algorithm, determining the position of the target in the picture frame and controlling the pan / tilt according to the result of the weighted average Steps such as driving the camera to move so that the target is located in the central area of ​​the picture frame. The present invention determines the position of the target in the field of view of the camera by means of the weighted average of the recognition results of the mean shift algorithm and the recognition results of the Kalman filter algorithm, has high recognition accuracy and can adapt to different backgrounds, and thus is suitable for non-fixed cameras Video object tracking. The invention is widely used in the technical field of image processing.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a video object tracking method, system, device and storage medium. Background technique [0002] In the fields of human-computer interaction and video surveillance, it is necessary to lock and track specific targets such as faces or license plates in videos. The existing video target tracking technology is mainly applied to fixed cameras, and when it is applied to non-fixed cameras driven by equipment such as pan / tilt, since the field of view of the non-fixed camera may change, the existing video target tracking technology may The inability to adapt to the frequently changing field of view background results in the inability to accurately track video targets. Contents of the invention [0003] In order to solve the above technical problems, the object of the present invention is to provide a video object tracking method, system, device and storage medium. [0004] On...
