Rotor operation flying robot target tracking method and system

Abstract

The invention belongs to the technical field of visual target tracking, and discloses a rotor operation flying robot target tracking method and system, and the method comprises the steps: taking a Siamfc framework as the basis, introducing Resnet50 as a feature extraction network through offset learning, enabling the network to learn more semantic information, and coping with the appearance changeof a target; according to the tracking network, a target scale estimation module is newly added on the basis of a classification discriminator, an IOU of a target bounding box and a target real box can be predicted, the target bounding box is accurately predicted, iterative correction is carried out on the bounding box through reverse gradient, and thus the network can accurately predict the scale change of a target; output of different layers of the network is fused by utilizing Resnet50 multi-layer feature output and adopting a residual fusion strategy, so that the robustness of the algorithm is further improved, the network performance is improved, the discrimination capability of the network to a small target is guaranteed, and finally, accurate tracking of the target is realized.

Problems solved by technology

[0006] The difficulty in solving the above problems and defects is: by introducing a deep network such as ResNet50, in theory, the feature extraction network can learn more abundant target information. This kind of performance will degrade the performance of the tracking algorithm

In addition, the prediction of the target scale module is a complex task, which requires the network to learn more semantic information rather than some shallow fea
