Description
Technical field：
The invention belongs to human body sitting posture correcting technology field, more particularly to a kind of collection human body contour outline characteristic information judge and
The intellectual apparatus for correcting of sitting posture during correction read-write, the device can be arranged on any position of those who read and write's surrounding, be adapted to blue or green few
In year academic environment, and technology is simple and reliable.
Background technology：
Teenager's sitting posture has close relationship with body development, sight protectio.Abnormal sitting posture really easily causes backbone two
Side force unbalance, so as to oppress spinal cord and nerve, can cause lumbago, serious meeting causes paraplegia or spinal canal stenosis, influence
Respiratory system, digestive system, the blood circulation system of patient, so as to cause adolescent idiopathic disease --- scoliosis.This
Outside, physiological stress increase of the posture leaned forward for a long time to muscle, ligament and interverbebral disc is kept to cause green grass or young crops in learning process of bending over the desk
Juvenile nonspecific low back pain.Furthermore, for a long time, closely and under strong light or dim light see that written word causes the regulation of eyes different
It is often nervous, eye fatigue, so as to cause myopia or myopia development.Teen-age standard sitting posture is required：The positive shoulder of head is risen on one's feet straight foot
It is flat, the chi of paper one of having hallucinations, hand is from nib one-inch, and chest is from the fist of table edge one.The self-disciplining of teenager in itself is poor, people's reading
It is difficult to adhere to always as requested when study, and parent supervises in time and efforts be extremely difficult to always at one's side.In
State patent of invention CN104951081B discloses the method and its intelligent early-warning device of a kind of automatic identification read-write posture, and it passes through
Human body recognition technology determines the sitting posture of those who read and write, and detailed process is：The coloured image and depth image obtained in imaging sensor
On the basis of, several are obtained by mode identification method and may make up sign read-write head part, face or shoulder 3 d pose net
Characteristic point, then by 3 d pose net be in standard read/write posture when the corresponding measurement data be set as that canonical parameter is deposited
Enter in the identification module, then the corresponding measurement data of dynamic read-write people is compared with canonical parameter, by comparison result
Exported by audio signal.But the apparatus structure is complicated, cost is high, and the human body being related to sets technology also in theoretical research
Stage, technology realizes that difficulty is larger, and how using a kind of convenience, intuitively method realizes that the correction to read-write sitting posture becomes urgently
The problem of need to solving.
The content of the invention：
Present invention aims to overcome that the shortcoming that prior art is present is there is provided a kind of intellectual read-write sitting posture correcting device,
