Abstract

The invention provides a human body motion measurement method and a system based on computer vision and electronic equipment, and the method comprises the steps: obtaining a human body motion video stream through a human body motion measurement method based on optics, and extracting a current reference image and a current frame image from the human body motion video stream; according to the current reference image and the current frame image, obtaining motion information of image pixel points in the current frame image through calculation, obtaining human skeleton key point coordinate information in the current frame image, and at least according to the motion information of the image pixel points in the current frame image and the human skeleton key point coordinate information, obtaining the motion measurement information of the human body joint motion through calculation, and combing semantic vision and motion vision, so that the human body motion measurement method is more convenient to operate, and the obtained motion measurement information is more robust.

Description

【Technical field】 [0001] The invention relates to the field of human motion measurement, in particular to a computer vision-based human motion measurement method, system and electronic equipment. 【Background technique】 [0002] Existing human body motion measurement methods can be roughly divided into two categories: 1. Measurement methods based on inertial motion sensors. This type of method often requires sensor components to be fixed on various parts of the human body, and the weight of the sensor itself often seriously affects the body itself. Movement will distort the measurement data, resulting in inaccurate calculation and evaluation, and there are large errors, and the preparation work of this method is also relatively cumbersome, which brings inconvenience to users. 2. Optics-based human body motion measurement methods. Currently, this type of method requires binocular or even multi-eye cameras, which need to be marked on the human body to collect and identify key p...
