Embodiment Construction
[0055] A bottom-up approach to multi-person pose estimation using bounding box constraints, including the following steps:
[0056] (1) Bounding box detection: Use YOLOv2 (J.Redmon and A.Farhadi, "Yolo9000: better, faster, stronger," arXiv preprint arXiv:1612.08242, 2016.) as a human detector to obtain the bounding box of the person in the picture B i ;
[0057] (2) Obtain network output: send the picture into the neural network we designed to obtain the confidence map and direction field information of the picture, and the neural network is obtained by the following methods:
[0058] Obtain training samples from the data set, take pictures as input, and use the confidence map S of 14 joints corresponding to each picture j and 13 directional fields L c As output, j=1,2,…,14; c=1,2,…,13, for neural network training network structure in Z.Cao, T.Simon, S.-E.Wei, and Y.Sheikh, "Realtime multi-person2d poseestimation using part affinity fields," arXiv preprint arXiv:1611.08050...
