A device and method for detecting human head rotation

Abstract

The invention provides a device and a method for detecting turning of a human head. The device comprises a high-speed video camera, an image acquisition card, an upper computer, a position mark module and a display screen; the high-speed video camera is connected with the image acquisition card by a video signal line, an output end of the image acquisition card is connected with the upper computer, the position mark module comprises a cap, a jacket and three mark color blocks, three mark modules are respectively positioned on the cap and left and right shoulders of the jacket, pixel blocks corresponding to the mark color blocks are extracted from a video processed by a master control program in the upper computer, and are counted, two pixel blocks are contained in an image instead of the original three pixel blocks when the human head turns by an angle larger than 45 degrees, the human head turning frequency is obtained by the aid of variation of the quantity of the pixel blocks, and detection results are displayed on the display screen. The device and the method for recognizing movement of the human head have the advantage that the device and the method can be applied to multiple fields of biology, kinematics, the subject of health preservation and the like.

Description

technical field [0001] The invention relates to a motion detection device, in particular to a detection device for head rotation of a human body. The invention also relates to a detection method for human head rotation. Background technique [0002] In recent years, the incidence of cervical spondylosis has been on the rise. The incidence is closely related to people's occupational factors, and it shows a trend of younger age. The emergence of this occupational factor may be related to the increasing pressure of social competition, the shortening of people's daily activities, the prolongation of desk work or study time, and the weak awareness of health care, which makes the neck muscles and ligaments in a state of tension for a long time. Cervical spondylosis can cause inflexible rotation in mild cases, and can lead to diseases in other systems, such as arteriosclerosis, high blood pressure, coronary heart disease, etc. in severe cases, and may even cause paralysis, which s...

Problems solved by technology

[0004] If the twisting of the cervical spine is simply to repeat mechanical movements, it will often be boring and difficult for people to persist. Therefore, the purpose of moving the cervical spine and entertaining the body and mind can be achieved by participating in some physical exercise activities. The experiment taken by the present invention The environment is based on a person's cervical spine movement during table tennis, and the current methods for detecting cervical spine movement during exercise are cumbersome and inconvenient to use
