英文摘要 |
In order to improve the accuracy of real-time RGB–D target occlusion tracking and solve the problems of
model drift and tracking loss in multi-target occlusion tracking, this paper proposes a multi-target occlusion tracking algorithm
based on RGB–D spatio-temporal context model. Firstly, the multi-target detection and location region is obtained,
and then the target temporal context model and the target spatial context model are used to establish the target RGB–D
spatio-temporal context model through target spatio-temporal context feature extraction. Then, when the tracker judges
the tracking state, the color and depth features are adaptively fused by calculating the time consistency to determine the
target position in the current frame. Finally, when the tracker discriminates multi-target occlusion, the depth probability is
introduced, and the depth probability information feature is used to constrain. The maximum a posteriori (MAP) correlation
model is used to effectively solve the problem of target occlusion tracking. The qualitative comparison experiments and
quantitative results on public datasets clothing store dataset and Princeton tracking benchmark dataset show that the proposed
algorithm has good occlusion tracking performance, can better solve the problem of multi-target occlusion tracking,
and improve the accuracy and robustness of target occlusion tracking. |
