And determine the rate of ventilation of air-conditioning according to this, reach fresh air volume required for accurately calculating room according to respiratory rate, thus
It determines the purpose of rate of ventilation, to realize the technical effect for improving accuracy, and then solves due to traditional ventilation time
Several calculating is the lower technical problem of rate of ventilation accuracy caused by being estimated according to room-size and number.
In the following, being illustrated as shown in Fig. 2 (a) to the air conditioning control method of the present embodiment:
Step a opens ventilatory.
After user opens ventilatory, air-conditioning enters the mode, and camera starting is continuously shot user video and carries out figure
As crawl, chest position is judged.
Step b detects user's respiratory rate.
As shown in Fig. 2 (b), detection user's respiratory rate includes the following steps:
Step b1 opens camera.
Step b2, control camera grab image.
Step b3 determines chest position.
Breathing can bring more apparent movement of thorax, but camera is not aware that position or even the medicine in chest
On also do not have accurate description to chest position.In the present embodiment, according to the position of human body head (face), according to
Certain proportionate relationship positions chest region.
Specifically, to determine chest position, face location need to be first determined, in practical applications, human face region is acquiring
Image in occupy biggish area ratio, be the local that color compares concentration, the present embodiment extracts face by Skin Color Information
Portion region.
As shown in Fig. 2 (c), face location determination includes the following steps:
Step b31 reads in color image.
Step b32, the colour of skin differentiate.
Step b33, the Morphological scale-spaces such as opening and closing operation.
Opening and closing operation is also common method in Morphological scale-space.Opening operation is first to do to expand again to object progress etching operation
The process of operation, closed operation are then first to carry out the process that etching operation is done in expansive working again to object.The effect of opening operation be
The small object of very thin junction segmentation object, erasing makes the boundary of big object more smooth without substantially changeing its area.Close fortune
The minuscule hole of big interior of articles can be filled by calculating, and the breaking portion of big object is reconnected, allow big object boundary more
It is smooth without substantially changeing its area.
Corrosion and expansion are two kinds of most basic, most important Morphological scale-space methods in image procossing, are various advanced shapes
The basis of state processing, a lot of other Morphology Algorithms is combined by them.Corrosion, is to be with a starting point
The structural element of image origin moves in entire plane, and total element is enabled to be in the region that is corroded in plane
Inside, then the collection area for meeting the centre coordinate of the structural element of this condition is exactly corrosion image.The result of corrosion
It is that object small one is allowed to enclose, object edge is shunk；But if object is integrally less than structural element, corrode just as rubber
Wipe object.Expansion, with corrosion on the contrary, being moved in entire plane with the structural element that a starting point is image origin, energy
Enough so that the structural element has at least one pixel Chong Die with the region that is corroded in plane, then meeting this condition
The collection area of the centre coordinate of structural element is exactly expanding image.Expansion can generally make the big circle of object, the edge of object to
It extends out, " fat " one encloses, and expansion can also usually reconnect two parts of the same object broken apart in original image.
Step b34, grey level's projective distribution.
Step b35 determines face up-and-down boundary.
Step b36, gray scale vertical projection distribution.
Step b37 determines face right boundary.
Step b38, determines face location.
Firstly, reading in the color image for thering is camera to shoot；Then, colour of skin differentiation is carried out, captured image is carried out
Gray proces, the up-and-down boundary of face is determined according to Morphological scale-spaces such as opening and closing operations, and exports face upper-lower height a；It determines
The right boundary of face, and the width b that exports face or so.
The width b of face is obtained according to the method described above, and the reckoning of chest position is carried out after height a.With face up-and-down boundary
Lower boundary on the basis of, move down coboundary of the b/2 as chest, then move down lower boundary of the b/2 as chest, the width in chest region
Degree is the width b of face, can thus obtain the region in chest.
Step b4 extracts each frame chest area grayscale value.
Step b5, frame number are the integral multiple of K.
Step b6, Wavelet Denoising Method.
As shown in Fig. 2 (d), Wavelet Denoising Method includes the following steps:
Step b61 carries out wavelet multi-scale analysis.
Step b62, low-pass filtering.
Step b63, reconstruction signal.
For natural light irradiation on the position of chest, the fluctuating in chest will lead to the variation of the overall intensity in the region.Every breathing
Once, chest rises and falls primary, and a cyclically-varying also occurs for gray scale.Shoot the video of one section of long period, then to video into
The method of row processing, directly carries out spectrum analysis to grey scale signal, so that it may can obtain the average respiration of this period.For
Obtain the behavioral characteristics that human body respiration changes over time, per at regular intervals, such as: 2s, 5s, 10s time carry out primary
Data processing can obtain dynamic respiratory rate as far as possible.
1, signal acquisition
Into after ventilatory pattern, camera is opened, unlatching timing, after image stabilization, can be directed to former pictures, be carried out
Face datection and the positioning of chest position, after determining chest position, are continuously shot, and each frame image of acquisition is carried out at gray scale
Reason, and chest location variation data are represented by curve out.
2, noise is removed
In measuring system, due to background environment noise in camera hardware, collection process, the walking about etc. of user,
Video gradation signal collected is the aliasing signal with noise.Therefore it needs to carry out signal processing using certain method,
Remove noise.Common removal noise method has frequency domain digital filtering, Wavelet transformation, independent component analysis, empirical modal point
Analysis etc..
In recent years, wavelet theory has obtained very fast development, and since it has good time-frequency characteristic, thus
Practical application is also very extensive.In denoising field, denoising is carried out using small echo and also obtains extraordinary effect.Specifically
Wavelet noise-eliminating method has a characteristic that
(1) low entropy, the sparse distribution of wavelet coefficient, so that the transformed entropy of image reduces；
(2) multiresolution, the method due to using multiresolution, it is possible to very well portray the non-stationary of signal
Feature, such as edge, spike, breakpoint；
(3) decorrelation, because wavelet transformation can carry out decorrelation to signal, and noise has albefaction to become after the conversion
Gesture, so wavelet field is more conducive to denoise than time domain；
(4) base flexibility is selected, since wavelet transformation can convert base with flexible choice, thus to different application, to not
Same research object, can select different wavelet mother functions, to obtain optimal effect.
Wavelet noise-eliminating method include the steps that three it is basic: to noisy acoustical signal carry out wavelet transformation；Transformation is obtained
Wavelet coefficient carries out certain processing, to remove noise wherein included；To treated, wavelet coefficient carries out wavelet inverse transformation, obtains
Signal after to denoising.The difference of Wavelet noise-eliminating method concentrates on the first step.
Mathematically, the essence of Wavelet Denoising Method problem is a function approximation problem, i.e., how to stretch by wavelet mother function
In the function space that contracting and translation version are transformed into, according to the weighing criteria of proposition, most preferably approaching to original signal is found, with complete
At the differentiation of original signal and noise signal.The optimum mapping from actual signal space to wavelet function space is namely found, with
Just the optimal recovery of original signal is obtained.
From the angle of signal, the problem of Wavelet Denoising Method is the filtering of signal, and although largely small echo
Denoising can regard low-pass filtering as, but since signal characteristic can also be successfully reserved after denoising, so in this regard
It is better than traditional low-pass filter again.It can be seen that Wavelet Denoising Method is actually the synthesis of feature extraction and low-pass filtering function.
Signal is mapped to wavelet field, different property is had on different scale according to the wavelet coefficient of noise and noise
And mechanism, the wavelet coefficient of signals and associated noises is handled.Essence is the wavelet coefficient for reducing cancelling noise and generating, to greatest extent
Reservation actual signal coefficient, inverse wavelet transform obtains the optimal estimation of signal.
Step b7 shows respiratory waveform.
In order to obtain continuous breath signal, sets every 2s and carry out a data processing, denoised later by wavelet method
It can obtain the respiratory rate curve as shown in Fig. 2 (e).
Step b8, peak detection.
For example, as soon as the case where statistics minute inner curve peak value, can obtain the respiratory rate of user per minute.
Step b9, obtains respiratory rate.
Step b10 shows respiratory rate.
Step c is compared with standard respiratory rate.
Respiratory rate preset in obtained respiratory rate and database is compared, can judge the oxygen demand of user, together
When can determine that the rate of ventilation in room.
Step d, if in critical field.
If so, executing step e；
If it is not, executing step f.
Step e, takes a breath according to default value.
Step f, if respiratory rate is rapid.
If so, executing step g；
If it is not, executing step h.
Step g increases rate of ventilation.
Step h, if respiratory rate is slow.
If so, executing step i.
Step i reduces rate of ventilation.
Respiratory rate of the normal adult in calmness is about 16 to 20 times per minute.With the difference at age, respiratory rate
Difference, the age, smaller respiratory rate was also big；Respiratory rate also increases when movement；Respiratory rate reduces during sleep.It can from above-mentioned material
Respiratory rate is identical with metabolism rate change trend out, therefore respiratory rate can be used to determine the oxygen demand in room, to control
Ventilation volume or rate of ventilation processed.
It when the respiratory rate detected is within [16,20], is then carried out according to normal rate of ventilation or ventilation volume, such as 30
m3/(h·p)；
When the respiratory rate detected is within (0,16), then rate of ventilation or ventilation volume, i.e. 20m3/ (hp) are reduced；
When the respiratory rate detected is within (20,50), then increase rate of ventilation or ventilation volume, i.e. 40m3/ (hp).
It should be noted that carrying out respiratory rate judgement using the gray scale of image using camera in this programme, while can adopt
With optical identification method, supercritical ultrasonics technology etc. can not contact technique monitoring user respiratory rate；Bracelet, respiration transducer can also be used
Etc. the respiratory rate of accessible method monitoring user.
The air conditioning control method of the present embodiment calculates user's respiratory rate using camera；Face position is judged using gray scale hair
It sets, so that it is determined that chest position；It is handled using Wavelet-denoising Method for data；Room ventilation time is determined by respiratory rate
Number, solves the problems, such as that sensor measurement respiratory rate and Air conditioner air exchange number are difficult on air-conditioning to be accurately calculated,
Fresh air volume required for accurately calculating room according to respiratory rate is reached, so that it is determined that rate of ventilation, borrows camera, pass through
Software analysis can calculate the purpose of the respiratory rate of user.
