Really control allows the light efficiency of LED Landscape Lighting to adjust control more convenient, effective.
In the following, the light efficiency adjustment control method and system with regard to LED Landscape Lighting provided by the invention are specifically described.
As shown in Fig. 2, one embodiment of the invention provides a kind of light efficiency adjustment control method of LED Landscape Lighting, comprising:
S100 obtains scene live image, LED operation network is identified from scene live image.
Controlling terminal 100 controls LED scene network 300 and works, to generate expected display effect.To LED scene
The display effect of network 300 is shot, and scene live image can be obtained.Scene live image reflects LED scene network
300 actual displayed effect.Scene live image can be sent to controlling terminal 100, then carry out figure to scene live image
As analysis, to identify LED operation network.
LED scene network 300 includes several LED light set of strings 310, and each LED light set of strings 310 specifically includes again
Multiple LED；LED scene network 300 can specifically regard the network of multiple LED compositions as.When LED scene network 300 works,
LED in LED scene network 300 shines, and expected pattern or animation effect is presented in integral LED jointly.It is shown relative to LED
For screen, in Landscape Lighting field, the LED distribution on LED scene network 300 is relatively sparse, thus, scene scene photo
LED as in is also sparse distribution, is not that all pixels point in scene live image all corresponds to LED.Therefore, it is necessary to from
LED pixel point is identified in scene live image.
By carrying out image analysis to scene live image, LED pixel point can be identified, to obtain LED operation network.
LED operation network includes the image data of the LED pixel point position and each LED pixel point in scene live image.Relative to
For the background (such as building or landscape) for laying LED scene network 300, the LED in LED scene network 300, bright
In terms of degree, color and dynamic change, there is apparent difference.It is thereby possible to select one or more features, existing from scene
LED pixel point is identified in field picture, to obtain LED operation network.
It is exemplary, it can be according to brightness, to identify LED pixel point from scene live image.Relative to background
For, the LED location in scene live image, brightness should be higher, LED scene network 300 could be allowed to show expected
Pattern or animation effect.Therefore, one kind is achieved in that, the brightness of each pixel in scene live image is analyzed, by brightness
Pixel more than preset threshold is determined as LED pixel point, should be LED pixel point more than the position of the pixel of preset threshold
Position；Then the picture number by the image data of the corresponding pixel in position of the LED pixel point, as the LED pixel point
According to.
Further, it is influenced by the reflection of light caused by the object of the periphery LED, there are one for the peripheral region LED to have
The reflected light region of stronger brightness, may the pixel brightness in reflected light region be more than preset threshold, and be misidentified as
LED pixel point.This problem, it is particularly evident when preset threshold is relatively low.At this point it is possible to identify threshold brightness position therein
It sets, using the threshold brightness position as LED pixel point position, then by the picture number of the corresponding pixel in LED pixel point position
According to image data as the LED pixel point.It is understood that brightness pole directly can also be carried out to scene live image
Threshold brightness location confirmation is LED pixel point position by value analysis.
It is exemplary, can also there are the characteristics that variation, according to the display effect of LED to identify from scene live image
LED pixel point.Relative to brightness and color for constant background, the LED in LED scene network 300 according to demand, bright
There is dynamic variation in terms of degree, color.Therefore, available at least two frames have the scene scene photo of different display contents
Picture identifies the picture with display effect difference (such as brightness and/or heterochromia) by comparing multiframe scene live image
Vegetarian refreshments position, as LED pixel point position, then by the image data of the pixel of the LED pixel point position, as the LED
The image data of pixel.It can be specifically to allow two frame scenes that identifying, which has the scheme of the pixel of brightness and/or color change,
Live image is subtracted each other, to obtain the different information of two frame scene live images, when different information is not 0, or be greater than it is default poor
When different value, that is, think that the corresponding pixel position of the different information is LED pixel point position.
Influence of the noise to LED pixel point position is determined when further, in order to reduce shooting, before step S100,
300 display brightness of LED scene network and/or color, which can also be controlled, has the source images of larger difference, for example multiframe is shown not
With the source images of primary colours.Meanwhile using multiframe scene live image identification LED pixel point when, can be set one it is biggish
Default difference value, to exclude influence of noise when shooting.Certainly, difference value is preset, it can also be aobvious according to LED scene network 300
Difference size of the source images shown in brightness and/or color is determined, for example the certain proportion conduct of difference size is default
Difference value.In this way, default difference value can be set dynamically, LED pixel point is recognized accurately.
S300 obtains LED network layout viewing, maps LED operation network and LED network layout viewing, obtains LED real work
Data.
LED network layout viewing specifically reflects in LED scene network 300 position of LED and its between controller 210
Connection relationship.Exemplary, as shown in Figures 3 and 4, LED network layout viewing may include each LED light in LED scene network 300
The position of set of strings 310 and its connection relationship between controller 210, the position of LED and phase in LED light set of strings 310
Connect relationship.
LED scene network 300 can be single plane, or plane stereo can also be curved surface object.According to
The different spaces structure of LED scene network 300 is presented, and LED network layout viewing both can be also possible to plan view with perspective view.For
Reduction data processing difficulty facilitates processing, and preferably LED network layout viewing is planar structure, may include one as needed
Or multiple partial LED network layout viewings.
When LED scene network 300 is plane, as shown in Figures 3 and 4, LED network layout viewing can be two dimension view,
According to actual effect, LED network layout viewing can integrally be rendered as the two-dimension plane structures such as matrix, polygon, arc, circle.When
When LED scene network 300 is plane stereo, as shown in figure 5, the plane stereo can be split into multiple sides, each side
The partial LED network layout viewing of a corresponding planar structure.
When LED scene network 300 is curved surface object, if wherein some side is plane, one can be corresponded to
The partial LED network layout viewing of planar structure；It can be a planar structure by the curved surface projection if side is curved surface
The surface decomposition can also be multiple section lines by partial LED network layout viewing, the corresponding planar structure of each section line
Partial LED network layout viewing, as shown in Figure 6.Section line refers to when going one solid of cutting with a plane, in three-dimensional table
The intersection formed on face.We can use a vertical plane, to cut the curved surface object or curved surface side, thus
Section line is obtained, is placed with LED on section line.In order to facilitate control, the LED on each section line can whole or segmentation
Connection, then connect with one or more controller 210.
It, will be in LED operation network mapping to LED network layout viewing after obtaining LED network layout viewing.Specifically, can adopt
The mode compared with image realizes the mapping association between LED operation network and LED network layout viewing.It is exemplary, it can be with LED
Job network is connected with the boundary LED in LED network layout viewing, while the two is adjusted to identical size, is then carried out
The matching between LED in LED pixel point and LED network layout viewing.Matched principle is the LED pixel with same position
LED in point, LED network layout viewing can Corresponding matching together.It is understood that in order to make matching more accurate, fast
Speed can also carry out rotation processing to LED operation network and LED network layout viewing, to allow the two to keep before being matched
Identical angle.Meanwhile for the ease of obtaining the boundary LED in LED operation network, boundary LED can control with different
Display effect, for example higher brightness, higher colour temperature effect are alternatively, different color.
In order to avoid excessively stringent location matches require to lead to the problem of it fails to match, when in LED network layout viewing
When some LED is not matched to LED pixel point, it can continue to match in predeterminable area around the LED corresponding position.It should
The size of predeterminable area can be determined according to LED spacing in LED network layout viewing.In general, the radius of the predeterminable area
The half of LED spacing should be less than, to avoid the LED pixel point for being matched to adjacent LED corresponding position.
Further, if some LED in LED network layout viewing, its corresponding position and around in predeterminable area,
When being not matched to LED pixel point, and according to source images, when which should have image data, it can be determined that the LED
It has damaged.In order to avoid error, multiframe scene live image can use to be judged, if being all not matched to LED
Pixel just judges that the LED has been damaged.
In order to facilitate the matching between the LED in LED pixel point and LED network layout viewing, set in LED network layout viewing
Set feature locations LED.So-called feature locations LED refers to that corresponding LED pixel point has totally different in periphery in scene live image
The identification feature of the LED pixel point in region, for example there is higher brightness, different colors etc., and the identification feature and be somebody's turn to do
Feature locations LED has corresponding relationship.As long as identification has the LED pixel point of the identification feature in scene live image,
It can directly match as one in this feature position LED or multiple feature locations LED.When there is multiple feature locations LED
When, respective identification feature can be different, in favor of the matching of feature locations LED and corresponding LED pixel point；Respective identification is special
Sign can also be identical, so needs multiple feature locations LED to cooperate and positions, could complete and of corresponding LED pixel point
Match.By the way that feature locations LED is arranged, LED network layout viewing, LED operation network can be divided into more by feature locations LED and boundary
A matching area, the matching between LED in LED pixel point and LED network layout viewing can be only in the respectively described Matching band
It is carried out in domain.In this way, matching can be allowed more accurate.
It is understood that can use feature locations LED, in order to make matching more accurate, quick to assist to LED
The rotation processing of job network and LED network layout viewing, for example, judging whether the angle of rotation is full according to feature locations LED
Foot is expected.
When LED scene network 300 be plane stereo or curved surface object when, LED network layout viewing may include have it is multiple
Partial LED network layout viewing respectively corresponds to not ipsilateral or section line.At this point, corresponding not ipsilateral or section line, it should
At least one scene live image frame is obtained respectively, forms scene live image by all scene live image frames.It is corresponding different
The scene live image frame of side or section line, it is preferred to use the face side or the visual angle of section line plane, in favor of rear
The matching in face.
Further, when LED network layout viewing corresponds to multiple section lines, controlling terminal 100 can also be controlled, with for the moment
Carve the work of only one section line.In this way, available scene live image frame identical with section line quantity, each section line
In corresponding scene live image frame, only corresponding section line work.In this way, can simplify the LED picture in LED operation network
The matching treatment between LED in vegetarian refreshments and LED network layout viewing.
When completing the matching between the LED in LED pixel point and LED network layout viewing in LED operation network
The image data of corresponding LED display point is given to corresponding LED, as the LED field evidence.It is understood that LED
Field evidence may include one of display effects data such as brightness, colour temperature or a variety of.
It should be noted that LED pixel point in LED operation network can when the size of LED scene network 300 is larger
It can not be corresponded with the LED in LED network layout viewing.At this point, a LED pixel point in LED operation network, need with
Multiple LED in LED network layout viewing are matched.
