AI Technical Summary

Problems solved by technology

In the existing technology, there is still a lack of tracking verification of the tracking target. Therefore, after the current frame tracking target tracking offset / error, in the subsequent tracking process, the target tracking may be based on the tracking offset / error reference frame , causing offsets / errors to accumulate, causing the entire trace to fail

Embodiment Construction

[0024] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0025] When the target is tracked in real time based on video images, a frame is usually selected in real time from the image of the known tracked target position as a reference frame, and the position of the tracked target in the current image frame is calculated based on the position of the tracked target in the selected reference frame. position, so as to realize the real-time tracking of the tracking target.

[0026] Please refer to figure 1 , is a video image-based real-time target tracking device disclosed in this embodiment, the tracking device includes: an image acquisition module 1, a tracking target reference frame position determination module 2, a tracking target current position calculation module 3 and a tracking target verification module 4 ,in,

[0027] The image acquisition module 1 is used to acquire the curren...

Abstract

The present application discloses a method / device for real-time tracking of a target based on a video image: obtain the position of the tracking target in a reference frame, calculate the position of the tracking target in the current frame based on the position, and then use the feature matrix at the calculated position based on The verification model judges whether the tracking target of the current frame is successfully tracked, thereby improving the correctness of the tracking, thereby reducing the probability of wrongly tracking the tracking target; further, using the coherence model to calculate the morphological coherence of the tracking target to determine whether the verification model needs to be updated, The classifier is preset to ensure the sustainability of tracking.

Description

technical field [0001] The present application relates to the field of video and image information processing, in particular to a method and device for real-time tracking of a target based on video images. Background technique [0002] Target tracking is an active video monitoring method. After an emergency occurs in the monitoring scene or an interested target is detected, the target is actively locked. By continuously estimating the offset, adjusting the camera angle, anxiety and other parameters, to achieve the goal of continuous tracking. Through continuous tracking, the complete trajectory and detailed feature information of the target can be captured, providing data support for emergency analysis, target behavior analysis of interested targets, and public security organs handling cases. [0003] Usually, when the tracking target is tracked in real time, a frame is selected from the image frames whose position is known to be tracked as a reference frame to assist the t...
