Embodiment Construction

[0027] An analysis of the existing technology found that the existing technology mainly relies on the judgment of professionals to determine whether there are hidden risks in sports actions, which has the problems of high cost and strong subjectivity, and cannot give an accurate and objective assessment of each individual's sports posture . In recent years, artificial intelligence algorithms based on deep learning have developed by leaps and bounds in the field of computer vision. However, the current implementation mainly focuses on the classification of single-frame images and face recognition, and cannot be obtained in the judgment of motion posture. Accurate three-dimensional information, and the assessment of motion risk cannot be obtained from the image.

[0028] The embodiment of this specification provides a method for risk assessment and correction of human body movements based on visual images, including automatically obtaining the three-dimensional space coordinate ...

Abstract

The invention discloses a method, device and equipment for automatically carrying out injury risk assessment and action correction on human body movement actions based on visual images. The method comprises the steps: automatically obtaining the track of three-dimensional coordinates of important joint nodes through employing a deep learning and filtering algorithm according to a human jump and landing video collected by a camera, and calculating related risk factor variables according to the coordinate track, evaluating the motion risk according to a calculation result, and giving a correction method. Related risk factors calculated by the method are results summarized by a large number of exercise injury researches. The evaluation method does not need human intervention at all, can accurately calculate the coordinates of the joint nodes and related risk factors, and gives targeted correction according to different risks of each person, so that the evaluation method has important significance in the aspect of reducing sports injuries.

Description

technical field [0001] The present application relates to the field of computer image processing, and in particular to a method, device and equipment for assessing the risk of injury and correcting human motion based on visual images. Background technique [0002] With the people's widespread awareness of sports, the participation rate of various sports is getting higher and higher. However, sports injuries, especially for young people, not only have a negative impact on personal health, but also have a huge impact on society. burden. A number of studies have shown that the posture during exercise has a great correlation with the occurrence of sports injuries. For example, many injuries during jumping come from incorrect landing postures. Traditionally, posture correction requires the guidance of professional coaches, but limited by the scarcity of professional coaches, the high cost of guidance, and the inability to evaluate posture in an objective way, it is difficult to ...
