Service life.
Based on above-mentioned hardware structure, when implementing, correction user can be realized by carrying out simple Function Extension according to demand
Sitting posture.
After user sits just before the correcting sitting posture table 1, the first camera 12 captures the first side figure of active user,
And the realtime graphic of the first camera 12 capture is shown on the display 16.User according to the realtime graphic of the first camera 12,
Judge whether itself neck is in the field of view center of camera, if otherwise controlling the first camera to adjust by expand 117
Device 18 moves in the two-dimensional direction, until clerical workforce's neck is in the field of view center of camera, as shown in Figure 3.
First camera 12 gathers the second side image of the current sitting posture of active user and sent to the single-chip microcomputer
Minimum system 11, the second side image include the second index point.The current sitting posture of second side graphical representation active user,
And real-time sitting posture, using the second index point as comparison point.Second side image can change with time and change.
The single-chip minimum system 11 is taken the photograph according to relatively described first index point of second index point described first
As the displacement of first 12 visual field judges active user's sitting posture.For example, the first index point and the second index point are respectively first side figure
The centre of form of head zone in picture and second side image.The single-chip minimum system 11 has data-handling capacity, and it can be with
The coordinate of the first index point and the second index point is obtained according to centroid calculation formula.When the second index point with respect to the first index point to
When diagonally forward is moved, user's sitting posture is judged to lean forward.When the second index point moves with respect to the first index point to rear ramp, judge
User's sitting posture is layback.When the second index point moves with respect to the first index point to front, user's sitting posture is judged to put down forward
Move.When the second index point moves with respect to the first index point to dead astern, user's sitting posture is judged to translate backward.As shown in figure 4,
A0Represent the first index point, A1Second index point at 1 moment is represented, then sitting posture of the user at 1 moment is layback.As shown in figure 5,
A0Represent the first index point, A2Represent second index point at 2 moment, then user 2 moment sitting posture for lean forward as shown in fig. 6,
A3Second index point at 3 moment is represented, then sitting posture of the user at 3 moment is to translate forward.As shown in fig. 7, A0Represent the first mark
Point, A4Second index point at 4 moment is represented, then sitting posture of the user at 4 moment is to translate backward.
It is all that sitting posture is bad to lean forward, swing back, translating forward and translating backward.The single-chip minimum system 11 is judging to work as
When preceding user's sitting posture is bad, the voice module 15 is controlled to send voice to remind the user.
The direct picture of the acquisition system user of second camera 13 is simultaneously sent to the single-chip minimum system 11.Institute
Second camera 13 is stated to gather the direct picture of active user and send to the single-chip minimum system 11.The single-chip microcomputer is most
Mini system 11 is contrasted the direct picture of the direct picture of the active user and the system user, is judged described current
Whether user is system user.When it is not system user to judge the active user, the single-chip minimum system 11 can be with
Display whether the active user being added to system user using display 16, user can be selected using expand 117
Yes/no.If user's selection is that the single-chip minimum system 11 stores the direct picture of active user, extracts the current use
The face characteristic at family, and add characteristic information storehouse.User's identification is carried out using second camera 13, is easy to point user to store user
Sitting posture situation, facilitate consultation and contrast, can also avoid multi-user exchange in turn sitting when, because of None- identified, sitting personnel cause
Sitting posture erroneous judgement.
The infrared array sensor 14 measures active user's upper body to the distance of the infrared array sensor 14,
And the distance is sent to the single-chip minimum system 11.When the distance exceedes preset length and the active user
Direct picture in face characteristic disappear, the single-chip minimum system 11 judges that user leaves, and otherwise judges that user does not leave.
Accordingly, the single-chip minimum system 11 can count active user and enter to sit the time, and it is described enter sit the time and exceed default when
Between when, control the voice reminder of voice module 15 active user, prevent user's sitting to be harmful to the health.
The correcting sitting posture table 1 and system that the utility model embodiment provides, based on above-mentioned hardware structure, when implementing, root
The progress sitting posture identification of the camera 12 of single-chip minimum system 11 and first can be based on by carrying out simple Function Extension according to demand, and
When judging that active user's sitting posture is bad, by the voice reminder of voice module 15 active user, correction user's sitting posture is realized,
It is simple in construction, cost is low, be advantageous to promote the use of on a large scale.And it is possible to identify user by second camera 13, it is easy to point
User store user's sitting posture situation, facilitate consultation and contrast, can also avoid multi-user exchange in turn sitting when, because of None- identified
Sitting posture caused by sitting personnel is judged by accident.And whether user can be judged by second camera 13 and infrared array sensor 14
Leave, and counting user enters to sit the time, and it is described enter sit the time and exceed preset time when, control the voice of voice module 15
The user is reminded, prevents user's sitting to be harmful to the health.
