Title:
MODEL TRAINING METHOD AND APPARATUS, BODY POSTURE DETECTION METHOD AND APPARATUS, AND DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/089391
Kind Code:
A1
Abstract:
A model training method and apparatus, a body posture detection method and apparatus, and a device and a medium. The model training method comprises: inputting an image training sample corresponding to the current iteration into the current posture detection network model, and according to a data form of the image training sample, obtaining a first loss function corresponding to the current iteration; according to obtained camera parameters, performing re-projection processing on the current output result of the posture detection network model, and on the basis of a re-projection processing result, obtaining a second loss function corresponding to the current iteration; and on the basis of a fitting loss function formed by the first loss function and the second loss function, performing backpropagation on the posture detection network model to obtain a posture detection network model for the next iteration.
