The specific embodiment
The below describes embodiments of the invention in detail, and the example of embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or the element with identical or similar functions from start to finish.Be exemplary below by the embodiment that is described with reference to the drawings, only be used for explaining the present invention, and can not be interpreted as limitation of the present invention.
Fig. 1 is according to an embodiment of the invention based on the flow chart of the air conditioner energy saving control method of background modeling personage motion detection.As shown in Figure 1, the air conditioner energy saving control method based on background modeling personage motion detection according to the embodiment of the present invention comprises the following steps:
Step S101, the image by camera timing acquiring air conditioning area is to obtain a plurality of photos.
Particularly, within camera of the present invention can cover the process range of air-conditioning fully.If a camera can't satisfy, a plurality of cameras can be set, and then cover whole air conditioning area.
Step S102 carries out to a plurality of photos whether the personage is arranged in the Analysis deterrmination air conditioning area.
Particularly, adopt the model such as Gauss model to detect the background of a plurality of photos that collect.Utilize the mixing background modeling method to carry out the background image collection to continuous a plurality of photos, and all do filtering for each photo that collects, in order to smoothed image, then remove noise, to prevent that noise is to the interference of actual testing result.In one embodiment of the invention, constantly update the resultant error of background model to avoid scene changes to bring by the mode of iterative learning.In the process that different photos are compared, differentiate by frame difference method whether the personage is arranged in photo between the adjacent photo in a plurality of photos.
Step S103 when having the personage to occur in air conditioning area, judges according to the appearance situation of personage in a plurality of photos whether the personage leaves air conditioning area.
Particularly, judge at first in a plurality of photos that gather whether the personage is arranged in Preset Time.If all without the personage, judging does not have the personage to occur in air conditioning area.
In one embodiment of the invention, judge the situation of motion by the study of some photos, movement once in a while can not be enough to judge personage's state.For personage's state judgement, can carry out according to the needs of concrete scene time threshold and set.For example, time threshold is set as 5 minutes, if the time of nobody surpasses 5 minutes in air conditioning area, is judged to be inactive state, and namely the personage leaves.
Step S104, when the personage leaves air conditioning area, the air-conditioning automatic cut-off switch.
Particularly, according to the air conditioning area judgement whether someone exists, when not having the personage to occur in the inherent air conditioning area of Preset Time, the autoshutdown air-conditioning.As shown in Figures 2 and 3, show that when surpassing the photo that Preset Time collected in 15 minutes in this air conditioning area, nobody occurs, the autoshutdown air-conditioning.Above-mentioned Preset Time can according to specifically deciding, also can arrange according to demand voluntarily.
In one embodiment of the invention, a plurality of people are arranged in air conditioning area, when wherein everyone leaves and nobody occurs in Preset Time, think and close air-conditioning for inactive state in air conditioning area.
According to the method for the embodiment of the present invention, by a plurality of photos in shooting space, air-conditioning place, and it is analyzed to detect personage's motion conditions, and then automatically adjust air-conditioning, convenient for users, reduced simultaneously the waste of electric energy.
Fig. 4 is according to an embodiment of the invention based on the structured flowchart of the air conditioner energy saving controller of background modeling personage motion detection.As shown in Figure 4, the air conditioner energy saving controller based on background modeling personage motion detection according to the embodiment of the present invention comprises acquisition module 100, analysis module 200, judge module 300 and adjusting module 400.
Particularly, acquisition module 100 is used for image by camera timing acquiring air conditioning area to obtain a plurality of photos.
Within camera of the present invention can cover the process range of air-conditioning fully.If a camera can't satisfy, a plurality of cameras can be set, and then cover whole air conditioning area.
Analysis module 200 is used for a plurality of photos are carried out whether the personage is arranged in the Analysis deterrmination air conditioning area.
Particularly, analysis module 200 adopts the model such as Gauss models to detect the background of a plurality of photos that collect.Analysis module 200 utilizes the mixing background modeling method to carry out the background image collection to continuous a plurality of photos, and all does filtering for each photo that collects, and in order to smoothed image, then removes noise, to prevent that noise is to the interference of actual testing result.In one embodiment of the invention, constantly update the resultant error of background model to avoid scene changes to bring by the mode of iterative learning.Analysis module 200 differentiates by frame difference method whether the personage is arranged in photo between the adjacent photo in a plurality of photos in the process that different photos are compared.
Judge module 300 is used for when having the personage to occur in air conditioning area, judges according to the appearance situation of personage in a plurality of photos whether the personage leaves air conditioning area.
In one embodiment of the invention, judge module 300 comprises judging unit 310 and identifying unit 320.
Wherein, judging unit 310 is used for judging whether a plurality of photos that gather have the personage in Preset Time.
If identifying unit 320 is used for all without the personage, judging does not have the personage to occur in air conditioning area.
In one embodiment of the invention, judge module 300 is judged the situation of motion by the study of some photos, and movement once in a while can not be enough to judge personage's state.For personage's state judgement, can carry out according to the needs of concrete scene time threshold and set.For example, time threshold is set as 5 minutes, if the time of nobody surpasses 5 minutes in air conditioning area, is judged to be inactive state, and namely the personage leaves.
Adjusting module 400 is used for when the personage leaves air conditioning area, the air-conditioning automatic cut-off switch.
Particularly, according to the judgement whether someone exists of 300 pairs of air conditioning areas of judge module, when not having the personage to occur in the inherent air conditioning area of Preset Time, adjusting module 400 is closed air-conditioning.As shown in Figures 2 and 3, show that when surpassing the photo that Preset Time collected in 15 minutes in this air conditioning area, nobody occurs, the autoshutdown air-conditioning.Above-mentioned Preset Time can according to specifically deciding, also can arrange according to demand voluntarily.
In one embodiment of the invention, a plurality of people are arranged in air conditioning area, when wherein everyone left and nobody occurs in Preset Time, judge module 300 was just thought in air conditioning area for inactive state, then is closed air-conditioning by adjusting module 400.
According to the device of the embodiment of the present invention, by a plurality of photos in shooting space, air-conditioning place, and it is analyzed to detect personage's motion conditions, and then automatically adjust air-conditioning, convenient for users, reduced simultaneously the waste of electric energy.
Although the above has illustrated and has described embodiments of the invention, be understandable that, above-described embodiment is exemplary, can not be interpreted as limitation of the present invention, those of ordinary skill in the art is not in the situation that break away from principle of the present invention and aim can change above-described embodiment within the scope of the invention, modification, replacement and modification.
