Problems solved by technology

Based on this framework, the posture of the human body can be described and the key points of the skeleton can be identified, but there is still a lack of action recognition during the movement of the human body, and the existing human action recognition cannot achieve real-time accurate counting

Embodiment Construction

[0032] Such as figure 1 and figure 2 Shown, a kind of real-time human action recognition and counting method of the present invention comprises:

[0033] Step 10. Obtain video data, obtain human skeleton point data, and generate time-series action data;

[0034] Step 20, perform fixed-point judgment on the action data according to the position information of the skeleton point in the time context, and determine its action category;

[0035] Step 30: Acquire the action data of the determined action category, intercept the action data according to a time interval, analyze the relevant skeleton points involved in the intercepted action data, generate the action pattern sequence of the corresponding skeleton points, and calculate the The pattern distance between the action pattern sequence and the action pattern sequence of the predefined standard action sequence, judge whether the pattern distance is less than a threshold, if so, add 1 to the count, otherwise the count remains...

Abstract

The invention provides a real-time human body action recognition and counting method, which comprises the following steps: acquiring video data, obtaining human body skeleton point data, and generating action data of a time sequence; performing fixed-point judgment on the action data according to the position information of skeleton points in the time context, and determining the action category; intercepting action data according to a time interval, analyzing related skeleton points of the action data, generating an action mode sequence of the skeleton points corresponding to the action data, and calculating a mode distance between the action mode sequence and an action mode sequence of a predefined standard action sequence; judging whether the mode distance is smaller than a threshold value or not, if so, adding 1 to the count, otherwise, keeping the count unchanged; and returning the action category and a counting result, and updating and displaying on a user interface. According to the invention, action types are judged through fixed-point recognition, and actions are counted in combination with mode setting and distance calculation, so that real-time and accurate action recognition and counting operation is provided for a user.

Description

technical field [0001] The invention relates to the field of human motion recognition, in particular to a real-time human motion recognition and counting method. Background technique [0002] In the existing human motion recognition technology, a basic motion recognition framework is provided, which can realize the recognition of the bone point position of a single person or multiple people, and realize the pose estimation of human motion, facial expression, finger movement, etc. Based on this framework, the posture of the human body can be described and the key points of the skeleton can be identified, but there is still a lack of action recognition during the movement of the human body, and the existing human action recognition cannot achieve accurate counting in real time. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a real-time human motion recognition and counting method, which can realize real-time and a...
