Embodiment
The embodiment of the security window control platform based on image procossing of the present invention is carried out below with reference to accompanying drawings
Describe in detail.
The material of window, generally speaking, is divided into three major types：Wooden, plastic-steel, aluminium alloy.Three has his own strong points.
Plastic-steel：Because being plastic material, weight is small, and heat-proof quality is good, and price is relatively low.Because often
In face of exposing to wind and rain, the sun shines, so most allowing people to concern the anti-aging problem of plastic-steel window.In fact, the plastic-steel window of high-quality
Service life up to 100 years or so.
Aluminium alloy：Be not in problem of aging because being metal material, and firm, impact resistance, intensity are big.But
The weakness that aluminum window is easiest to be attacked is exactly heat-proof quality because metal be heat good conductor, it is extraneous with it is indoor
Humidity can be with the frame transmission of window.
But it is worth query, the ratio on a fan window shared by frame is simultaneously not very big, and window is not one block of metal
Plate, but the glass of frame is inlayed, the heat transmitted by frame edge strip actually can produce the indoor humidity for having warmer, air-conditioning
Great influence
But that precautions averts perils is good, this problem, employs " bridge cut-off " skill on the aluminium alloy window having in order to prevent
Art, i.e., add one layer of resin material in aluminum alloy window frame, thoroughly broken off the approach of heat conduction.
It is wooden：Comparatively, wooden should be forms frame material the most perfect, no matter from heat-insulated, sound insulation angularly
For have obvious advantage, and inherent texture and natural figure are more moving.It is actual although wooden
On some be used to doing the solid wood of window frame and have already been through processing special layer by layer, not only without moisture, it is desirable to which higher is even
Fat is sucked, so, so-called wooden actually as fossil, solid wood after treatment, is only protected
The appearance of timber has been stayed, quality is but completely different, will not cracking deformation, less suffers insect bite with worry, is corroded, moreover,
Intensity also greatly increases.
In addition, also a kind of frame structure is referred to as aluminium Bao Mu, the outdoor part of wood frame is one layer of aluminium alloy structure,
In fact, this be combine wood frame thermal insulation it is good and the advantages of intensity of aluminum alloy is high, integrate, maximize favourable factors and minimize unfavourable ones.
The wooden unique shortcoming of window is exactly that cost is too high.
Current window control model falls behind, and automatic window can not be carried out according to external circumstances or closes window control, in order to gram
Above-mentioned deficiency is taken, the present invention has built a kind of security window control platform based on image procossing, asked for solving above-mentioned technology
Topic.

In addition, image filtering, i.e., press down the noise of target image under conditions of image detail feature is retained as far as possible
System, is indispensable operation in image preprocessing, and the quality of its treatment effect will directly influence successive image processing and divide
The validity and reliability of analysis.
Due to the imperfection of imaging system, transmission medium and recording equipment etc., digital picture is in its formation, transmission log mistake
Often polluted in journey be subject to a variety of noises.In addition, some links in image procossing when the picture object inputted and are not so good as pre-
Also noise can be introduced when thinking in result images.These noises often show as one and cause the isolated of stronger visual effect on the image
Pixel or block of pixels.Generally, noise signal it is uncorrelated to the object to be studied it occur with useless message form, upset figure
The observable information of picture.For data image signal, psophometer is either large or small extreme value, these extreme values are acted on by plus-minus
On the true gray value of image pixel, the interference of bright, dim spot is caused to image, greatly reduces picture quality, influence image restoration,
The progress of the follow-up work such as segmentation, feature extraction, image recognition.A kind of wave filter for effectively suppressing noise is constructed to must take into consideration
Two basic problems：The noise in target and background can effectively be removed；Meanwhile can protect well image object shape,
Size and specific geometry and topological features.
One kind in common image filtering pattern is nonlinear filter, it is, in general, that when signal spectrum and noise frequency
Such as the noise as caused by mission nonlinear or there are non-gaussian to make an uproar when composing aliasing or when containing nonadditivity noise in signal
Sound etc.), traditional linear filter technology, such as Fourier conversion, while noise is filtered out, always blurred picture is thin in some way
Section (such as edge) and then the extraction property reduction for causing the positioning accuracy and feature as linear character.And nonlinear filter is
Based on a kind of Nonlinear Mapping relation to input signal, often a certain specific noise approx can be mapped as zero and retained
Signal wants feature, thus it can overcome the shortcoming of linear filter to a certain extent.

Body subgraph is detected to determine whether include a suspect in the human body subgraph；
The motor driver is also connected with a suspect's detection device, suspicious for including in the human body subgraph
During personnel, stop controlling the window of the direct current generator based on the indoor humidity in real time and the outside humidity in real time,
Sent to the direct current generator and close window control signal；
Wherein, when the motor driver is additionally operable in the human body subgraph not include a suspect, recover based on described
Real-time indoor humidity and the outside humidity in real time control the window of the direct current generator；
Wherein, the motor driver receive it is described close to standby signal when, to the direct current generator send stop rise
Control signal；
The inductance approach switch is vortex type proximity switch, including three pins, when the inductance approach switch approaches
During the sheet metal, second pin of the inductance approach switch is high level using as described defeated close to standby signal
Go out.
