Embodiment approach

[0113] As a specific implementation of the present invention, the following describes the visually accurate target tracking method of the present invention in conjunction with specific examples:

[0114] Figure 8 It is a schematic diagram of the first frame image of the present invention. refer to Figure 8 , detect the video data to obtain the first frame image A and the second frame image B, detect the first frame image A to obtain several original targets A1, A2...An, detect the second frame image B to obtain several tracking targets B1, B2... Bn, where n is a positive integer.

[0115] Specifically, obtain the center positions of the original targets A1, A2...An, and mark the center positions of several original targets as A1[X(n,1),Y(n,1)], A2[X(n,2), Y(n,2)]...An[X(n,n),Y(n,n)] (not shown in the figure). Get the center positions of several tracking targets, and mark the center positions of several tracking targets as B1[X(n+1,1),Y(n+1,1)], B2[X(n+1,2) ,Y(n+1,2)]......

Abstract

The invention provides a visual accurate target tracking system and method.The visual accurate target tracking system comprises a video data unit, a target detection unit, a distance calculation unit, a motion trend calculation unit and a judgment unit, and the distance calculation unit comprises a first position information operation module, a second position information operation module, and a distance comprehensive operation module which solves the problem of inaccurate visual target tracking calculation through a mode of jointly calculating distance calculation and a motion trend track so that accuracy of target tracking is improved. The distance calculation unit can quickly and accurately calculate the distance between the two targets. The method comprises the following steps: acquiring a plurality of original targets and a plurality of tracking targets, and calculating distances between the original targets and the tracking targets to obtain a plurality of tracking distances; and presetting a tracking distance threshold value, and judging whether the original target and the tracking target are the same target according to the tracking distance and the tracking distance threshold value or according to the motion trend track of the original target.

Description

technical field [0001] The invention relates to the technical field of visual target tracking, in particular to a visually accurate target tracking system and method. Background technique [0002] Moving object tracking is a method for processing, sampling and detection of video signals, which detects and marks specific areas contained in images through certain specific features. In recent years, many scholars have proposed many excellent tracking algorithms. The commonly used tracking algorithms mainly have the following three ideas: method based on feature matching, method based on region correlation and method based on model. [0003] It is one of the visual target tracking methods to track the target by calculating the previous distance of the target in two adjacent frames. However, if there is overlap between two targets or the distance is very close, there will be a problem of target tracking calculation error. [0004] The invention patent application with the publi...
