Further, said method also comprises fresh-keeping chamber is divided into 9 regions, a light emitting devices of the corresponding nine grids in top in each region, when same article storage is in multiple region, the light emitting devices in each region is all luminous, and the intensity of illumination of each light emitting devices becomes the 70%-90% of original intensity of illumination.
By adopting above technical scheme, the present invention possesses following beneficial effect: by arranging image acquiring device in the fresh-keeping chamber of refrigerator, thus judge the article of fresh-keeping indoor storage, control according to different article the illumination that light emitting devices sends varying strength, thus make fresh-keeping effect better.
Accompanying drawing explanation
Fig. 1 is specific implementation flow chart of the present invention.
Detailed description of the invention
Below in conjunction with Figure of description, the present invention is further detailed explanation.
The invention discloses a kind of photosynthetic antistaling refrigerator based on image recognition, it specifically comprises fresh-keeping chamber, image acquiring device, image processor, light control unit and light emitting devices, described fresh-keeping chamber comprises the dividing plate above bottom surface, the surrounding sidewall surrounded and fresh-keeping chamber, described image acquiring device is arranged in fresh-keeping chamber, for obtaining the image of the article of fresh-keeping indoor storage; Described image acquiring device is connected with image processor signal, and the image of the article of the fresh-keeping indoor storage obtained is sent to image processor by image acquiring device, and image processor judges the Item Title of fresh-keeping indoor storage; Judged result is sent to light control unit by described image processor, and light control unit controls the luminescence of light emitting devices according to judged result, and different article, light emitting devices sends different intensities of illumination.By arranging image acquiring device in the fresh-keeping chamber of refrigerator, thus judging the article of fresh-keeping indoor storage, controlling according to different article the illumination that light emitting devices sends varying strength, thus making fresh-keeping effect better.Such as in light control unit, set mushroom, auricularia auriculajudae does not need illumination, light emitting devices is closed; Asparagus lettuce, pea sprouting, radish low-light; Cucumber, tomato, green pepper, apple intense light irradiation.The fresh-keeping different light setting of concrete various article is carried out according to its different characteristics, and this does not belong to emphasis of the present invention, and in this not go into detail.
Further, in order to meet the requirement at the different article of the fresh-keeping indoor storage of refrigerator, the light emitting devices in the present invention is multiple, is evenly arranged on below fresh-keeping chamber dividing plate, each light emitting devices independently controls, and provides illumination for giving the article in fresh-keeping chamber.Such as when light emitting devices is 9, below the dividing plate of the distribution of shapes of nine grids above fresh-keeping chamber, each light emitting devices independently controls, and provides illumination for giving the article near in fresh-keeping chamber.
Further, above-mentioned light emitting devices is circular, and circular light emitting devices is arranged on circular minute surface, and the size of minute surface is greater than the size of light emitting devices, forms two concentric circles.Reflective mirror is positioned at below fresh-keeping chamber dividing plate equally, and each reflective mirror is circular, places circular light source in the middle of circular, by reflective, make Light distribation even, irradiates more abundant to vegetable melon and fruit.
Further, above-mentioned image acquiring device is colour imagery shot, and colour imagery shot is arranged on the sidewall of fresh-keeping chamber, the dividing plate of position above fresh-keeping chamber.Be arranged on the image can more clearly taken in fresh-keeping chamber herein, and by the image transmitting that photographs to image processor, image processor carries out judgement according to the CF of vegetable melon and fruit and obtains vegetable melon and fruit classification, after judging the classification of vegetable melon and fruit, light control unit controls the light emitting devices work of vegetable melon and fruit proximal most position, controls the intensity of illumination of this light source.
The invention also discloses a kind of implementation method of the photosynthetic antistaling refrigerator based on image recognition, after it specifically comprises the following steps: step one, user's closing refrigerator panel, image acquiring device obtains the image of the article of fresh-keeping indoor storage, and the image of the article of the fresh-keeping indoor storage obtained is sent to image processor; The Item Title that step 2, image processor judge fresh-keeping indoor storage according to image and the position of depositing; Judged result is sent to light control unit by step 3, image processor, and light control unit controls the intensity of illumination of the light emitting devices of corresponding region according to judged result.By arranging image acquiring device in the fresh-keeping chamber of refrigerator, thus judge the article of fresh-keeping indoor storage and the position of article, send the illumination of varying strength according to the light emitting devices of different article control corresponding region, thus make the fresh-keeping effect of different article better.
Further, said method also comprises when there are the article that can not identify in fresh-keeping chamber, and the display screen of refrigerator shows, and prompting user is referred to similar classification.By said method, further facilitate the use of user, close vegetable melon and fruit options for user can also have been provided according to CF and select.
Further, when said method is also included in and carries out photosynthetic antistaling, display screen is pointed out: photosynthetic antistaling carries out.Photosynthetic antistaling has discontinuity, can determine the time span of photosynthetic antistaling time equally according to vegetable melon and fruit classification.
Further, said method also comprises fresh-keeping chamber is divided into 9 regions, a light emitting devices of the corresponding nine grids in top in each region, when same article storage is in multiple region, the light emitting devices in each region is all luminous, and the intensity of illumination of each light emitting devices becomes the 70%-90% of original intensity of illumination.The piece image that colour imagery shot collects, image is divided into 9 regions by image processor, a light source of the corresponding nine grids in top in each region.Such as: it is the light characteristics reading cabbage after cabbage that image processor identifies first region, and light control unit is according to the light emitting devices above Characteristics Control cabbage region.If certain vegetable melon and fruit appears at multiple region, then the light emitting devices in multiple region all can work, but the intensity of each light emitting devices can decay to the 70%-90% of original intensity of illumination, and the interval size of amplitude depends on whether this region has other vegetable melon and fruits.
Here by specific embodiment, invention has been described in detail, there is provided the description of above-described embodiment in order to make those skilled in the art manufacture or use the present invention, the various amendments of these embodiments are easy understand for a person skilled in the art.The present invention is not limited to these examples, or some aspect wherein.Scope of the present invention is described in detail by additional claim.
