Embodiment Construction

[0026] The solutions of the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings.

[0027] In the following description, for purposes of illustration rather than limitation, specific details, such as specific system architectures, interfaces, and techniques, are set forth in order to provide a thorough understanding of the present application.

[0028] The term "and / or" in this article is just an association relationship describing associated objects, which means that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist simultaneously, and there exists alone B these three situations. In addition, the character " / " in this article generally indicates that the contextual objects are an "or" relationship. In addition, "many" herein means two or more than two.

[0029] In order to enable those skilled in the art to better understand the technical solution of the present...

Abstract

The invention discloses a target tracking method, a terminal and a computer readable storage medium thereof, and the target tracking method comprises the steps: obtaining at least two frames of imagesamples comprising a tracking target, and determining a first region frame of the tracking target from the image samples; collecting a current frame, and judging whether the matching degree of the current frame and the tracking target of the first region frame in the previous frame image is greater than a set value or not; if yes, determining the running speed of the tracking target based on the position information of the first area frame; predicting to obtain an initial prediction area of the tracking target through the position information and the running speed of the first area frame; andperforming feature extraction on the first region frame and the initial prediction region, and determining position information of the tracking target in the current frame in response to a feature extraction result. According to the target tracking method provided by the invention, motion estimation and feature matching are combined, and the robustness and universality of a tracking target are improved.

Description

technical field [0001] The present invention relates to the technical field of target tracking, in particular to a target tracking method, a terminal and a computer-readable storage medium thereof. Background technique [0002] Object tracking is one of the hotspots in the field of computer vision research. Object tracking has a wide range of applications in many fields such as video surveillance, navigation, military, human-computer interaction, virtual reality, and automatic driving. In simple terms, object tracking is to analyze and track a given object in a video to determine the exact location of the object in the video. [0003] Most of the current target tracking methods determine the candidate area of ​​the target to be tracked in the current frame image according to the area where the target to be tracked in the previous frame image is located. Existing target tracking methods cannot effectively and accurately track the tracking target with fast movement or abrupt ...
