Abstract

The invention relates to a human body key point extraction method and a device, a readable storage medium and equipment. The method comprises the steps of receiving a target image containing a human body image part; extracting a target human body feature map in the target image; inputting the target human body feature map into a key point extraction model to obtain a human body key point heat map;wherein the key point extraction model comprises a first sub-model and a second sub-model, the first sub-model is used for obtaining a human body key point heat map according to the target human bodyfeature map, and the second sub-model is used for obtaining key point regression coordinate information according to the target human body feature map; wherein the loss value of the key point extraction model is determined according to the loss value of the first sub-model and the loss value of the second sub-model. Through the method, the accuracy of the extracted human body key points can be effectively improved, and the user experience is improved.

Description

Technical field [0001] The present disclosure relates to the field of image processing, and in particular, to a method, device, readable storage medium, and equipment for extracting key points of the human body. Background technique [0002] When extracting key points of an image, in the prior art, the key points of the image are usually extracted through a convolutional neural network, and the marked images are uniformly trained. However, when the image contains too many people, if the two people are relatively close, it is difficult to distinguish the key points of the different people in the above method when determining the key point of one of the people. Summary of the invention [0003] The content of the invention is provided to introduce concepts in a brief form, and these concepts will be described in detail in the following specific embodiments. The content of the invention is not intended to identify the key features or essential features of the technical solution requ...
