A human body key point detection system and method based on complex scenes

Abstract

The invention discloses a human body key point detection system and method based on complex scenes. The method includes: inputting monitoring video information to obtain a single-frame static image and a multi-frame optical flow image; extracting the single-frame static image through a convolution operation Features to obtain the feature map, in order to solve the impact of the interference target on the detection of the human target in complex scenes, the human target detection algorithm is used to distinguish the actual confidence of the feature map from the preset confidence, and obtain the discretized human target bounding box; For multi-frame optical flow maps, optical flow stacking is used to form a two-dimensional vector field; features in the discretized human target bounding box are extracted to obtain feature maps, and key points and correlation degrees of parts are obtained, and the predictor is used to generate parts for each part of the human body. Position information map, through the part position information map and two-dimensional vector field to realize the accurate detection of the key points of the human body. The system and method of the present invention are used for detecting key points of a human body in a complex scene, and realize accurate detection of key points of a human target.

Description

technical field [0001] The invention relates to a human body key point detection technology, in particular to a human body key point detection system and method based on complex scenes. Background technique [0002] At present, my country's "Skynet" project has begun to take shape. With the development of advanced technologies such as deep learning and intelligent video behavior analysis, how to effectively use surveillance video has become the focus of video data analysis. [0003] Computer video surveillance is the use of computer vision and image processing methods to perform target detection, target classification, target tracking, and behavior recognition of personnel targets in the surveillance scene on image sequences. Among them, human body behavior recognition is a research hotspot that has been widely concerned in recent years, and human body key point detection is the basis and core key technology of intelligent video behavior recognition. Through the analysis an...
