Head Pose Estimation Model Based on Deep Learning

Aiming at the problem that the spatial structure information of traditional head pose estimation network is easy to lose,this paper proposes a head pose estimation network model combining capsule network and traditional convolutional neural network. The model uses a traditional convolutional neural network with a multi-level output structure to extract spatial structure information and semantic information at different levels. At the same time,the advantages of the capsule network can fully retain the feature information and encode the extracted features,so that the features can transfer and output in the form of a capsule,effectively avoids the problem of loss of spatial structure information. The experimental results show that the average absolute errors of the proposed model on the AFLW2000 and BIWI datasets are 5.68 and 4.33,respectively,which further improves the accuracy of head posture estimation,and has good robustness on lighting changes and occlusion under indoor conditions.
