Human body key point detection method and device, storage medium and terminal equipment

Abstract

The invention discloses a human body key point detection method. The method comprises the steps of obtaining a to-be-detected human body image; based on a preset key point detection network, obtaining a human body key point prediction heat map according to the to-be-detected human body image, wherein the key point detection network takes a preset Gaussian response heat map of a human body part as supervision information, and the Gaussian response heat map is pre-constructed according to a connection relationship between a human body data set and preset human body key points; and detecting the positions of the human body key points according to the human body key point prediction heat map. Correspondingly, the invention further discloses a human body key point detection device, a computer readable storage medium and terminal equipment. By adopting the technical scheme of the invention, human body key point detection can be carried out in combination with constraints between human body structure information, thereby reducing quantization errors and improving the accuracy of a detection result.

Description

Technical field[0001]The present invention relates to the field of image processing, and more particularly to a key point detection method, apparatus, computer readable storage medium, and a terminal device.Background technique[0002]The human key point detection is designed to detect the specific position of the articles, facial features, etc. of the image, to describe the human attitude, in the natural image, the complexity of shooting scenes and the human gesture diversity gives a huge challenge to the human attitude estimation task . As one of the most challenging topics in the field of computer visual technology, diversified human gesture estimates the emergence of data sets and the development of deep learning techniques, making the accuracy of human key detection are gradually improved, commonly used representative Human key detection network has HOURGLASS, CPN, MSPN, and HRNET, etc., these key points detection network based on confidence hot maps, mostly use multi-level featu...
