Embodiment

[0027] Embodiment: a kind of human body posture behavior intelligent analysis and recognition method of the present embodiment, such as figure 1 shown, including the following steps:

[0028] S1: Establish a behavioral analysis model, including the following steps:

[0029] S101: collecting sample video data;

[0030] S102: Extract all relevant nodes of each human body in each frame image in the sample video, connect all relevant nodes of each human body segmentally and partly, connect all relevant nodes belonging to the same human body, and finally merge into a person's overall skeletal framework;

[0031] S103: Connect the same joint points of each human body in two adjacent frames of images to form a space-time map of each human skeleton frame;

[0032] S104: Collect feature information on all relevant nodes in the time-space diagram of each human skeleton frame, use a SoftMax classifier to classify behaviors, and classify behavior feature categories;

[0033] S105: Per...

Abstract

The invention discloses a human body posture behavior intelligent analysis and recognition method. The method comprises the following steps: collecting sample video data; extracting all joint points of each human body in each frame of image in the sample video, and connecting all joint points of each human body in a segmented and partial manner; connecting the same joint point of each human body in two adjacent frames of images to form a space-time diagram of each human body skeleton framework; classifying the behaviors by adopting a SoftMax classifier, and dividing behavior feature categories; performing deep learning according to the divided behavior feature categories, and training a behavior analysis model; collecting a human body posture behavior video to be analyzed, extracting a space-time diagram of each human body skeleton framework in the video, inputting the space-time diagrams into the behavior analysis model, and analyzing the behavior category of each human body in the video by the behavior analysis module. Human body posture behaviors are analyzed and recognized through feature extraction, behavior modeling and behavior classification, and the accuracy is high.

Description

technical field [0001] The invention relates to the technical field of human body behavior recognition, in particular to an intelligent analysis and recognition method for human body gestures and behaviors. Background technique [0002] The intelligent analysis and recognition of human body posture and behavior extracts the behavior-related information contained in the data by analyzing video or image data, thereby establishing a bridge between the underlying data and high-level semantic understanding of behavior. There is a semantic gap between the low-level expression of the content and the high-level expression. How to eliminate this semantic gap is a problem that content understanding has been trying to solve. [0003] In the existing technology, the video containing the human body is generally shot by the camera; then, the human body image is extracted from the video, and the human skeleton is detected from the human body image area, and the behavior of the human body i...
