Chip 1 is controlled to be electrically connected.The light intensity signal that control chip 1 is detected according to light intensity detection unit 7 exports electric current by adjusting
Achieve the purpose that adjustable desk lamp brightness.
Image collecting device 2 is miniature webcam, can be fixed in connecting rod, can also be set on extension bar by magnetic adsorption plate
There is aperture, miniature webcam is placed in inside connecting rod, miniature webcam passes through the aperture and acquires image information.
Miniature webcam is every to cross Image Acquisition of T0 moment progress, and acquired image information is transmitted to the control
Chip 1, control 1 pair of acquisition image of chip carry out target point mark, the distance between target point are calculated, at a distance from setting
Threshold value compares, if measured distance exceeds distance threshold range, carries out sitting posture prompting by speech prompting device 3.
Target point includes: crown point, chin point, left shoulder point, right shoulder point and human body axis.
Utility model works process is as follows: after infrared detector 6 detects that someone enters image-capture field, control
Chip 1 starts miniature webcam work, and speech prompting device 3 prompts user to get out standard sitting posture, miniature webcam acquisition mark
Quasi- sitting posture image is transmitted to control chip 1, and control chip 1 carries out standard target point mark to standard sitting posture image, determines mark
Accuracy vertex position, standard chin point, the left shoulder point of standard, standard right shoulder point and standardized human body's axis.Miniature webcam
Every to cross Image Acquisition of T0 moment progress, still by the image transmitting of acquisition to control chip 1, control chip 1 sits standard
Appearance image carries out target point mark, determines crown point, chin point, left shoulder point, right shoulder point and human body axis, counts
The distance between target point is calculated, is compared with the distance threshold of setting, as shown in Figure 2:
(1) when human body axis is consistent with standardized human body's axis, right and left shoulders is compared with standard right and left shoulders point under position
It falls, then bow-backed behavior has occurred in judgement, and 3 call user's attention back of speech prompting device is straight and upright；
(2) when height reduces compared with standard header vertex position and chin point for crown point and chin point, if people at this time
Body axis is consistent with the corresponding target point of standard sitting posture image with right and left shoulders position, and the crown and chin level height reduce
Amplitude beyond setting threshold value when, then judgement has occurred the behavior of bowing, and 3 call user's attention of speech prompting device comes back；
(3) when human body axis is consistent with the standard target point of standard sitting posture image with right and left shoulders position, the crown is under
Bar point offset human body axis, then inclined head behavior has occurred in judgement, and speech prompting device 3 reminds user to correct head pose；
(4) when human body axis shifts compared with standardized human body's axis, it is judged as and produces inclination behavior, voice mentions
3 call user's attention of device of waking up should not body inclination；
(5) when left shoulder point, right shoulder point are not at same horizontal line, it is judged as and produces high-low shoulder behavior, voice
3 call user's attention of alarm set balances both shoulders.
When desk lamp position or height change, the signal that movable sensor 4 or radian detector will test is transmitted
To control chip 1, control chip 1 re-starts standard sitting posture Image Acquisition；Re-start standard target point mark.
After infrared detector 6 detects that user leaves image-capture field, in certain time, control chip 1 is exported
Sleep signal, image collecting device 2, speech prompting device 3, movable sensor 4 and radian detector enter dormant state,
It is energy saving until detecting that someone enters image-capture field next time, on the one hand reduce the operating procedure of user, separately
On the one hand the service life of each component is also extended.
Light intensity detection unit 7 is connect with control 1 input terminal of chip, and the optical signal that will test is converted to electric signal transmission
To control chip 1；8 input terminal of light adjusting circuit is connect with 1 output end of control chip, receives the current regulation of control chip 1
Signal, 8 output end of light adjusting circuit are connect with the headlamp on desk lamp.As shown in figure 3, light intensity detection unit 7 includes photosensitive electricity
