In the present embodiment, the Position Approximate that infrared imaging primarily determines personnel is used, then further sweep by camera
It retouches, in conjunction with the indoor environment map built in advance, further determines that the specific location of the personnel.After determining personnel positions,
Then the status information that the personnel are obtained into one again is found specifically, first passing through the face area that camera identifies the personnel
The eye locations of the personnel, the folding condition by obtaining personnel's eye primarily determine out the status information of the personnel.If
Eyes are in closed state, then can be determined that out that the personnel are in sleep state, then can according to when sleep to light intensity
Demand is adjusted accordingly, even if such as when daytime do not turn on light, but outdoor optical come in it is still very bright, needed for sleep
The light intensity wanted, then can be by starting intelligent curtain, by pull-up, the curtain achievees the purpose that block outdoor optical, so that
Indoor light intensity dies down, and improves the sleep quality of the personnel.And if personnel's eyes are in and open state, pay attention to acquisition here
The open and-shut mode of the eye of people is not flashy state, but the state of a bit of time, such as 2S, accordingly even when being
People blinks, and due to not being to be constantly in closed state, will not be determined in sleep state, but in running order.
Specifically, can be judged according to the frequency parameter that human eye is opened and closed.And when the personnel are in running order, work as collecting
After preceding light intensity, it can further judge whether current light intensity meets the range of light intensity needed for working condition, if incongruent
Words, then can be by controlling to adjust the light intensity for reaching required accordingly.That is we can also be tentatively according to sleep state
And working condition, two corresponding range of light intensity are set in advance, to meet primary demand of the personnel to light intensity, consequently facilitating subsequently
Judge accordingly and then carries out corresponding adjusting control.
Another embodiment of the method for the present invention, as shown in figure 3, including：
S100 obtains the coordinate position of indoor occupant；
S200 further obtains the status information of the indoor occupant according to the coordinate position of the indoor occupant；
S300 acquires the light intensity on the indoor occupant periphery；
S400 judges whether the indoor occupant currently needs according to the status information of the indoor occupant and the light intensity on periphery
Light intensity regulating is carried out, if so, entering step S500；
S510 judges whether the light intensity on the indoor occupant periphery is more than pre- when the indoor occupant is in sleep state
If sleep light intensity value；If so, entering step S520；
S520 closes corresponding intelligent illumination furniture or reduces the intensity of illumination that the intelligent illumination furniture provides；
S530 further obtains the behavioural information of the indoor occupant when the indoor occupant is in running order；
S540 judge the indoor occupant periphery light intensity whether in the indoor occupant behavioural information it is required
In range of light intensity；If it is not, entering step S550；
S550 further judges whether indoor occupant periphery light intensity is higher than needed for the behavioural information of the indoor occupant
Otherwise the range of light intensity wanted enters step S570 if so, entering step S560；
The illumination that S560 carries out shading or the reduction intelligent illumination furniture offer by the intelligent shading furniture of startup is strong
Degree reaches the required light intensity of the indoor occupant to adjust the indoor occupant peripheral light and shine；
The corresponding intelligent illumination furniture of S570 controls provides the required light intensity of behavioural information of the indoor occupant.
This method embodiment, can be further in the case of in running order to indoor occupant relative to previous embodiment
The behavioural information for analyzing the personnel is obtained, because it is also different that people, which carry out the different required light intensity of activity,.Work as people
Member is in sleep state, then will judge whether the current indoor light intensity of acquisition is more than preset sleep light intensity value, if super
If having crossed, then need to reduce indoor light intensity, such as by closing intelligent lighting lamp (intelligent illumination furniture) or reducing intelligence
The brightness of headlamp, requirement when meeting personnel's sleep to illumination.Certainly, if it is daytime, intelligent lighting lamp is not opened
In the case of, if current indoor light intensity is still higher than preset sleep light intensity value, can also by pull-up curtain or
Screen (intelligent shading furniture) reduces indoor light intensity, improves the sleep quality of the personnel.And if the personnel are in work shape
If state, then the behavioural information of the personnel can be obtained further, needed since different behavioural informations is corresponding with different light intensity
It asks, therefore, we can judge whether the light intensity currently acquired meets the required light intensity of this behavioural information accordingly.Certainly,
We can also classify to behavioural information according to light intensity demand, that is to say, that will believe the consistent behavior of light intensity range of needs
Breath is divided into same class behavior, and in other words the required light intensity of this class behavior is consistent.If current indoor light intensity is high
In the light intensity needed for the indoor occupant current behavior, then shading treatment can be carried out by starting intelligent shading furniture, or
Person reduces the light intensity of intelligent illumination furniture to meet demand of this behavior of the indoor occupant to illumination.Likewise, such as
Fruit current indoor light intensity is less than the light intensity needed for the indoor occupant current behavior, then can be by starting intelligent illumination furniture
Or the brightness of intelligent illumination furniture is adjusted come the needs of providing the light intensity needed for indoor occupant, meet the behavior to illumination.
Preferably, as shown in figure 4, in above method embodiment, the step S530 is in running order when indoor occupant
When, the behavioural information for further obtaining the indoor occupant specifically includes：
S531 obtains the sight of the indoor occupant by the camera when the indoor occupant is in running order
Range；
S532 is searched according to the indoor environment map built in advance and the location information of the intelligentized Furniture obtained in advance in institute
The intelligentized Furniture in the range of visibility of indoor occupant is stated, and obtains the coverage of the intelligentized Furniture in the range of visibility；
S533 chooses the range of visibility of the coverage and the indoor occupant, and there are the intelligentized Furnitures of intersection as standby
Select furniture；
S534 chooses the intelligentized Furniture opposite with the indoor occupant sight as target furniture from the alternative furniture；
S535 obtains the behavioural information of the indoor occupant according to the target furniture and its status information.
Above-mentioned flow provides a kind of method obtaining indoor occupant concrete behavior information.Specifically, judging the interior
After personnel are in running order, we further obtain the sight information of the indoor occupant by camera again, for example, such as Fig. 5 a
Shown, the horizontal viewable range of common people is the ken of 100--120 degree or so, we are for ranging from 100 degree with horizontal viewable
Example, turns left 50 degree from the sight a of centre visual angle, the 50 degree i.e. ken of 100 degree of composition level of turning right.In the horizontal direction, it only needs
Object in the region that sight b and sight c are constituted is believed that visual.Certainly, it is accustomed to eye according to the mankind, Wo Menguan
Note object when, sight does not deviate by the too far range of the object generally, therefore, we can also Selection Center visual angle sight
It turns left 35 degree, 35 degree of range of visibility for being set as human eye level of turning right.General human eye plumb visible range is a 130 degree or 140 degree left sides
The right side, Fig. 5 b are human eye vertical coverage schematic diagram (central field of vision is 3 degree or so).Likewise, can be accustomed to eye according to the mankind,
It sets human eye vertical coverage ranging from 70-80 degree or so (up 35 degree, down 35 degree of central vision).Horizontal line of sight range and hang down
Demand line range can be accustomed to being set in advance according to the mankind with eye.The present invention is not limited.By horizontal line of sight range and
Vertical coverage range, we can lock the region of human eye concern substantially, that is to say, that we can by the range of visibility of human eye
To lock the lookup region of intelligentized Furniture, and since the location information of each intelligentized Furniture gets (each intelligentized Furniture in advance
Have positioning function or had determined that the coordinate position of each intelligentized Furniture in advance), it is located at human eye sight then can quickly determine
Intelligentized Furniture in range.Certainly, we can also be scanned the region by camera and obtain intelligentized Furniture in the region, only
It is that operand is big by image recognition after scanning, and higher to system specifications if image recognition, therefore, preferably,
We are more easy by positioning the position of each intelligentized Furniture in advance, also significantly reduce the complexity and calculation amount of operation.
After determining the intelligentized Furniture within the scope of human eye sight, the shadow of each intelligentized Furniture in the region then can be got
Ring range.Such as smart television, immediately ahead of the screen of smart television institute to range as its coverage, for another example certain books,
Books can then be opened to coverage of the region as the books of page face.Its coverage of different smart homes
Different, can generally storage be set in advance in the coverage of each intelligentized Furniture by us, obtained convenient for follow-up search.Determine good person
After the coverage of an eye line range and intelligentized Furniture, it next can search and whether there is intersection therebetween, because if
There are intersection then can the preliminary judgement intelligentized Furniture may exist between the indoor occupant and be associated with, therefore, can be by this
A little intelligentized Furnitures are selected as alternative furniture.Then further according to the sight of the indoor occupant, the family of the indoor occupant sight face is searched
Tool, as target furniture.For example, the indoor occupant stares at TV, then can be using the TV as target furniture.Most
Afterwards, we can get the behavioural information of the indoor occupant according to intelligentized Furniture and the status information of the intelligentized Furniture.Than
Such as, target furniture is smart television, and the state of the TV is open state, then can judge the behavior letter of the indoor occupant
Breath is viewing TV.For another example, target furniture is books, and the state of the books is in an open state, then can judge the interior
The behavioural information of personnel is reading etc..
Another embodiment of the method for the present invention can more intelligent, simplicity be realization room using a kind of new solution
The linkage of inner light source.
In the present embodiment, indoor hardware components mainly need multiple high-definition cameras with infrared imaging function uniform
The top for being distributed in room, Fig. 6 be infrared camera scheme of installation, pass through the high-definition camera of multiple infrared imaging functions
Three-dimensional imaging is carried out to room inside.In addition, indoor intelligentized Furniture need to have positioning function, or in existing intelligentized Furniture
Install indoor positioning device additional.
The cardinal principle of the system software of the present embodiment can be divided into two parts：
1) to the judgement of human behavior and zone of action：By the infrared imaging function of the camera of indoor erection to room
Interior carry out thermal imaging, because the temperature of human body is relative constant, it is possible to hunt out people's within the scope of the temperature region
Approximate location, then the position of there may be face within doors is identified to carrying out recognition of face within doors by camera.Then
The region for the face position that can recognize that there will be the regional location of human body temperature and camera, which is set, carries out comparison comparison, then can be compared with
Accurately to judge the position coordinates of human body within doors, while avoiding the interference of the factors such as photo in region.Then pass through camera shooting
Head to the parameters such as the opening and closing frequency of eyes of human eye may determine that all personnel within doors be sleep be in working condition with
And their position and direction of visual lines, range of visibility.
2) the adjusting judgement of light source
Indoor intelligentized Furniture related with light is roughly divided into illuminating furnitures, light requirement furniture and shading furniture, and
Divide their coverage.
Illuminating furnitures (intelligent illumination furniture)：Refer to the furniture for having autonomous luminous power, such as：All kinds of lamps and lanterns, screen etc.
Light requirement furniture or region：It is to need furniture or the region of light source to refer in such equipment periphery activity：Such as：Passageway,
Closet, toilet, books etc..
Shading furniture (intelligent shading furniture)：Refer to marginal ray by blocking the furniture with adjustment effect.
Human behavior data (position, working condition, sight angle, the sight model analyzed by the preceding camera of reading
Enclose), and illuminating furnitures, light requirement furniture or region, the position of shading furniture and coverage are combined, take personnel's range of visibility and family
Has the intersection of coverage, it is possible to determine that going out personnel, there are incidence relations with which furniture.If there are light requirement men in range of visibility
Illuminating furnitures are then called in tool or region, and combine camera to the analysis of the light intensity in the region to carrying out light filling within the scope of this, hiding
