(x0,y0)；
Then planar stepping motor is moved to the rearmost end of abscissa, planar stepping motor laser beam is opened,
The position for recording image is (x1, y0), and it is n1 to record the step number of progressive motor；
Planar stepping motor is moved to the rearmost end of ordinate again, planar stepping motor laser beam, note is opened
The position for recording image is (x0, y1), and it is n2 to record the step number of progressive motor；
The pixel for finally obtaining a step-length of planar stepping motor is x0/n1=y1/n2；Then square region
Domain is the square area that (x0, y0) arrives (x1, y1).
In above-mentioned steps e, infrared inductor measurement can be taken pictures while obtaining human body temperature, be taken
Whether the scanning element of the infrared light of picture band, the scanning element can walk correct anti-as planar stepping motor
Feedback；If feedback is incorrect, planar stepping motor will re-calibrate position.
The mode that planar stepping motor corrects position again is to pass through the step-length and pair of pixel obtained before
Should be related to, and two-dimentional origin position (x0, y0)；When planar stepping motor goes to the location point of forehead
When (M, (N+N1)/2), the step-length abscissa walked from origin is (M-x0) * x0/n1, and ordinate is
(N+N1-y0)*x0/n1；Because the position of human body forehead is more close with the point, next planar stepping motor can
The step-length walked about is calculated by the point, position is corrected again to obtain the position of forehead.
Using cooperatively by camera, planar stepping motor and infrared inductor of the invention, can be quick
Accurately the temperature of measurement human body, measures simple and convenient, and can be with stored record child within a period of time
Temperature variations, the convenient health condition to child is monitored, and is particluarly suitable for kindergarten, primary school
Promoted the use of Deng place.

The unlatching and operating of machine 4；
Voice broadcasting system 7, on the riser 1 of human body temperature measuring instrument, infrared inductor 5 is surveyed
The data of amount carry out voice broadcast；
The riser 1 is arranged in a mutually vertical manner and linked together with horizonal base plate 2；
Wherein, using image and planar stepping motor device automatic measurement human body temperature method specific steps such as
Under：
A, it camera is arranged on can collect the position of human body head portrait, and delimit a square region
Domain, by four anchor points of four points of the square area as planar stepping motor device；
B, planar stepping motor determine position according to this four anchor points, and are moved in the region
It is dynamic；
C, need carry out measurement of bldy temperature human body station after the horizonal base plate of instrument, gravity sensor is got
Gravimetric data, controller knows that starting camera after the gravimetric data is taken pictures；
After d, camera are taken pictures, image is analyzed, the position to obtain forehead；
Concrete mode is：
Using the algorithm based on the colour of skin, according to Clustering features of the face complexion in color space, with normalizing
The method for changing RGB color comes out face from image with other background separations, obtains human face region figure
Picture；The human face region part is intercepted from original image again and out carries out image binaryzation, by the figure of binaryzation
As gray scale carries out vertical integral projection, drop shadow curve is obtained；Because the larger trough in curve is same face
Each organ characteristic is corresponding, such as observes from the bottom up, the most it is apparent that four troughs, are corresponded to bottom
Face, up a trough correspond to nose, the 3rd should be eyes, and the 4th is more than eyebrow.Cause
This needs to position third and fourth wave crest point in drop shadow curve；Then the right and left eyes region being cut out is divided
Do not handled, carried out because eye areas grey scale change is complex, then to the eye image after binaryzation
Mixed integrating method is projected, and determines that eye center point indulges N using horizontal integral projection, true by vertical integral projection
The horizontal M of centre mark, then (M, N) is exactly the center for the eyes to be positioned；Obtain the center (M, N) of eyes
Afterwards again by the marginal point N1 of head dummy on abscissa, the position for obtaining forehead is (M, (N+N1)/2)；
E, planar stepping motor are turned under the position of the forehead, are got by infrared inductor measurement
The temperature of human body is simultaneously reported by voice broadcasting system.
The determination mode of planar stepping motor position of the present invention is：First, planar stepping motor returns to machinery
Origin, opens the laser beam of planar stepping motor laser aid, and is taken pictures on plastics blank, will clap
According to obtained image lower-left point as two-dimentional origin, after image binaryzation, then can obtain image
Position is (x0, y0)；
Then planar stepping motor is moved to the rearmost end of abscissa, planar stepping motor laser beam is opened,
The position for recording image is (x1, y0), and it is n1 to record the step number of progressive motor；

The position for recording image is (x0, y1), and it is n2 to record the step number of progressive motor；
The pixel for finally obtaining a step-length of planar stepping motor is x0/n1=y1/n2；Then square region
Domain is the square area that (x0, y0) arrives (x1, y1).
In above-mentioned step e, infrared inductor measurement can be taken pictures while obtaining human body temperature,
The scanning element for the infrared light of picture band taken, whether the scanning element can walk correct as planar stepping motor
Feedback；If feedback is incorrect, planar stepping motor will re-calibrate position.
The mode that planar stepping motor corrects position again is to pass through the step-length and pair of pixel obtained before
Should be related to, and two-dimentional origin position (x0, y0)；When planar stepping motor goes to the location point of forehead
When (M, (N+N1)/2), the step-length abscissa walked from origin is (M-x0) * x0/n1, and ordinate is
(N+N1-y0)*x0/n1；Because the position of human body forehead is more close with the point, next planar stepping motor can
The step-length walked about is calculated by the point, position is corrected again to obtain the position of forehead.
Specific works mode of the present invention is：
People stands on the horizonal base plate of human body temperature measuring instrument, is passed by the gravity being arranged on horizonal base plate
Sensor obtains correlation values, and the numerical value startup camera that controller obtains gravity sensor transmission is taken pictures,
Determine the position of human body forehead；Then planar stepping motor drives infrared inductor to run in the region
The time that row measurement of bldy temperature, wherein infrared inductor carry out measurement of bldy temperature is 2~5 seconds, can be in the time model
The peak of measurement is taken in enclosing, it is ensured that the accuracy of measurement；After measurement is finished, infrared inductor again will be upper
State numerical value and pass to controller, controller sends order to voice broadcasting system, will by voice broadcasting system
The numerical value is quoted.
In actual applications, as the more prioritization scheme of the present invention, it can be set on human body temperature measuring instrument
