Problems solved by technology

[0007] Disadvantage 1 of the existing technology: Traditional multi-tracker fusion methods usually require artificially designed complex rules for model selection or result fusion
Usually these artificially designed methods contain a large number of hyperparameters, need to be carefully tuned, and generalization is difficult to guarantee under different data sets
[0008] Existing technology disadvantage 2: Previous multi-tracker fusion or selection methods need to run all trackers and determine the best tracker based on their individual confidence or mutual evaluation
Running multiple trackers at the same time makes it difficult to guarantee the overall tracking efficiency

Embodiment Construction

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

[0019] The embodiment of the present invention provides a switching target tracking method, such as figure 1 It mainly includes the following two parts:

[0020] 1. Using the two-way network with the anchored regional candidate network as the benchmark method, build a variety of different sub-trackers ( figure 1 The number of sub-trackers shown is an example only).

[0021] 2. In the current frame, use the pre-trained agent to determine the sub-tracker ...

Abstract

The invention discloses a switching target tracking method. , determine the sub-tracker of the current frame according to the current tracking environment and historical actions, and use the corresponding sub-tracker to track the target of the current frame. The method can improve the performance, reduce unnecessary operations, and greatly ensure the tracking speed.

Description

technical field [0001] The invention relates to the technical field of visual target tracking, in particular to a switching target tracking method. Background technique [0002] Visual object tracking is a fundamental and important task in the field of computer vision. Target tracking plays an important role in security monitoring, human-computer interaction, autonomous driving and other fields. [0003] In the visual target tracking task, the tracker can only obtain the information (position and scale) of the target in the first frame, and it is required to be able to track the target continuously in subsequent frames, so it is very challenging. Although the visual tracking technology has made obvious progress in recent years, the occlusion, deformation, fast motion, deformation of the target during the tracking process still greatly interfere with the performance of the tracking algorithm. [0004] In recent years, many different frameworks have emerged in the field of v...
