Embodiment Construction

[0060] In order to make the purpose, technical solution and advantages of this specification clearer, the technical solution of this specification will be clearly and completely described below in conjunction with specific embodiments of this specification and corresponding drawings. Apparently, the described embodiments are only some of the embodiments in this specification, not all of them. Based on the embodiments in this specification, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this specification.

[0061] Target tracking refers to the process of analyzing and processing the video collected by smart devices, and making full use of the information of the collected video to track the target stably. After the target is determined, the target's position, velocity, acceleration and other motion parameters can be obtained, and then the characteristic parameters of the target can be obtained....

Abstract

The invention discloses a target tracking method and device, equipment and a storage medium, and the method comprises the steps: carrying out the target detection of a first video frame in a to-be-processed video, obtaining a target object, and carrying out the target tracking according to the position of the target object in the first video frame and the motion vector corresponding to each video frame in the obtained to-be-processed video, and determining the position of the target object in each second video frame, thereby tracking the target object in each video frame of the to-be-processed video. It can be seen that only the first video frame in the to-be-processed video is subjected to high-precision target detection, the target detection precision is guaranteed under the condition of limited computing power, meanwhile, the position of the target object in the second video frame except the first video frame is determined through the motion vector, tracking of the target object is achieved, and the target object tracking efficiency is improved. And the real-time performance of target tracking is considered.

Description

technical field [0001] This specification relates to the field of computer technology, and in particular to a target tracking method, device, equipment and storage medium. Background technique [0002] With the development of visual computing technology, target tracking technology has been widely used in video broadcasting, security monitoring, driverless driving and other fields. The main task of target tracking is to continuously, real-time and accurately locate the tracked target object in the video sequence through the smart device. Among them, the target tracking can adopt the intensive tracking method, that is, use the target detection model to perform target detection on each frame of image in the video, and determine the position of the tracked target object in each frame of image, so as to realize the target detection. tracking. However, due to the limited computing power of smart devices (such as smart cameras), the frame rate of video images using target detecti...
