Embodiment Construction

[0029] Embodiments of the present invention are described below in conjunction with the accompanying drawings.

[0030] figure 2 A general flow chart of the target tracking method according to the embodiment of the present invention is shown. Such as figure 2 As shown, the target tracking method includes: a connected domain acquisition step S100, which can perform a three-dimensional connected domain analysis on the input initial depth image, and obtain a list of connected domains in the initial depth image; an initial target determination step S200, which can be in the initial depth image. Determine the target connected domain where the target is located according to the known current position of the target, and determine n feature points in the image part corresponding to the connected domain, where n is a natural number; the tracking step S300 can be input after the initial depth image In the subsequent depth image, perform three-dimensional connected domain analysis, a...

Abstract

The invention provides a target tracking method which comprises: a step of obtaining a connected domain, carrying out three-dimensional connected domain analysis on an input initial depth image to obtain a list of the connected domain of the initial depth image; a step of determining an initial target, determining a target connected domain where the target is in the initial depth image according to a currently known current position of the target, and determining n feature points in the image part corresponding to the connected domain, wherein n is a natural number; a step of tracking, carrying out three-dimensional connected domain analysis in the subsequent depth image input after the initial depth image, identifying the target connected domain where the target is in each candidate connected domain in the connected domain list of the subsequent depth image; and a step of determining the target position, namely tracking the n feature points in the target connected domain identified by the tracking step to update the current position of the target. A target tracking device is also correspondingly provided.

Description

technical field [0001] The invention relates to a target tracking method and a target tracking device. Background technique [0002] Target tracking is one of the most important technologies in the field of image analysis and machine vision. The main difficulty in target tracking is how to associate targets in continuous video frames, especially when the movement of the target object is faster than the frame rate. In the case of fast speed, target tracking is more difficult, and if the tracked target changes its orientation during motion so as to produce a certain degree of deformation, the complexity of this problem is further increased.
