Problems solved by technology

However, due to the time-consuming problems of the existing target tracking methods, the determined candidate area cannot be infinitely expanded, and due to the uncontrollability of the target to be tracked, it is easy to cause the target to be lost during the target tracking process.

Embodiment Construction

[0074] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0075] In the following, some terms used in the embodiments of the present application are explained, so as to facilitate the understanding of those skilled in the art.

[0076] (1) Color histogram, which is a color feature widely used in many image retrieval systems. It describes the proportion of different colors in the whole image, and does not care about the spatial position of each color, that is, it cannot describe the objects or objects in the image.

[0077] In the specific implementation process, for the color histogram, the abscissa is the color space, and the ordinate is the number of pixels of the color. There are 256×256×256=16777216 commonly used RGB coordinates, so there are too many abscissas, and the number of pixels corresponding to many abscissas is very small, and the entire his...

Abstract

The invention provides a target tracking method and a target tracking device, which are used for reducing the probability of target following loss in a target tracking process. The target tracking method comprises the following steps: for each target to be tracked in at least one target to be tracked, respectively determining at least two candidate regions from a current frame image according to at least two algorithms, and obtaining at least two candidate regions in total; wherein the at least one to-be-tracked target is determined from a previous frame of image of the current frame of image;determining a first candidate target set from the at least two candidate regions; and determining a candidate target matched with each to-be-tracked target from the first candidate target set.

Description

technical field [0001] The present application relates to the technical field of computer vision, in particular to an object tracking method and an object tracking device. 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. However, due to time-consuming considerations in the existing target tracking methods, it is impossible to expand the determined candidate area infi...
