Example Embodiment

[0030] The technical solutions of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0031] A method for intelligent evaluation of human posture and behavior in this embodiment, such as figure 1 shown, including the following steps:

[0032] S1: Human body joint point information extraction: Based on the CPM algorithm, the cascade structure is adopted, and the 18 human body joint points in each frame of the input video of the human posture and behavior to be evaluated are firstly found in a bottom-up manner, and then the human body joint points are found. Point combination (connect all the joints of the human body in sections and parts, and connect all the joints belonging to the same human body) to obtain the skeleton frame data composed of all the joints of the human body in the video;

[0033] 18 human body joints including nose, neck, right shoulder, right elbow, right wrist, left should...

Abstract

The invention discloses a human body posture behavior intelligent evaluation method. The method comprises the following steps: S1, extracting human body joint point information; S2, constructing feature vectors; S3, realizing action alignment; S4, analyzing action matching similarity; S5, realizing behavior evaluation. According to the method, the human body part feature vectors are constructed byutilizing the human body joint point information, the standard degree intelligent scoring of the to-be-evaluated human body posture behavior based on the reference human body posture behavior is realized on the formulated behavior similarity scoring system, and the evaluation accuracy is high.

Description

technical field [0001] The invention relates to the technical field of posture behavior evaluation, in particular to an intelligent evaluation method for human body posture behavior. Background technique [0002] In the prior art, the image containing the human body is generally captured by the camera first; then, the human body posture data is extracted from the image, and the posture data of the test human body is compared with the posture of the reference human body; finally, the evaluation and judgment results of the human body posture are given. [0003] The static evaluation of human body posture needs to collect posture images of 4 faces of the human body, comprehensively analyze and test the postures of the 4 faces of the human body, obtain the overall posture data of the test human body, compare it with the reference human body posture data in the database, and evaluate the posture of the test human body Judgment, however, this method can only analyze the static pos...
