Embodiment Construction

[0052] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0053] The present invention provides a real-time detection method of human bone joint points, please refer to figure 1 , through the following steps:

[0054] Step 1, get the detection data set.

[0055] In this embodiment, step 1 is implemented through the following process:

[0056] Step 11, obtain the detection data set D, the sample (X, Y)∈D in the detection data set, where X is the input human body image containing a single person, and Y is the corresponding joint point coordinate set representing the human body pose {y 1 ,y 2 ,...,y J}∈Y, J is the number of joint points.

[0057] Step 12, in order to generate the class labels required for training the coordinate set network, that is, the set of heat maps {h 1 ,h 2 ,..., h J}∈h, the coordinate set Y needs to be processed. Set the heat map h j The width and height are respectively W h and...

Abstract

The invention provides a real-time human skeleton articulation point detection method and belongs to the field of image processing. The invention designs a hierarchical context attitude detection network, digital image processing and deep learning are adopted for realizing real-time detection on coordinates of skeleton articulation points of human bodies under the conditions of different attitudes, different illuminations and different scale dimensions, a real-time detection method is realized while precision is guaranteed, calculation amount of a model can be obviously reduced, and model training, deployment and usage efficiency is guaranteed.

Description

technical field [0001] The invention belongs to the field of image processing, and in particular relates to a real-time human skeleton joint point detection method. Background technique [0002] In recent years, with the rapid improvement of hardware performance such as computer processors and computer image parallel processors, as well as the rapid development of deep learning research in the field of computer vision and the rapid application of algorithms, video surveillance technology has also developed rapidly. The intelligentization, platformization, and information linkage of video surveillance technology have been further developed, which can be said to be an indispensable link in the field of security. Video surveillance involves many fields such as image processing, traditional machine learning, deep learning, artificial intelligence, big data, cloud computing, etc. It is not only a problem of multidisciplinary integration, but also a subject of continuous developme...
