Title:
METHOD AND DEVICE FOR INTELLIGENT ESTIMATION OF HUMAN BODY MOVEMENT POSTURE BASED ON CONVOLUTIONAL NEURAL NETWORK
Document Type and Number:
WIPO Patent Application WO/2022/036777
Kind Code:
A1
Abstract:
The present application belongs to the field of deep learning computer vision. Disclosed are a human body movement posture intelligent estimation method and apparatus based on a convolutional neural network. The method comprises: inputting a human body image, on which movement posture estimation is to be performed, into a trained human body detection model to carry out processing to obtain an individual detection result; inputting the individual detection result into a trained global estimation model to carry out processing to obtain first feature images of human body key points at different scales; and inputting the first feature images into a trained supplementary fine-tuning model for to carry out processing to obtain second feature images of the human body key points at different scales by means of enhanced learning, wherein the supplementary fine-tuning model comprises a plurality of feature extraction branches, each feature extraction branch is equipped with a different quantity of fine-tuning modules, and the enhanced learning is performed by means of the fine-tuning modules of each feature extraction branch; and obtaining a human body posture estimation result on the basis of the second feature images at different scales. The present application effectively solves the problem of inaccurate body posture estimation caused by easily missing key points that are difficult to distinguish in a human body image in the prior art.
