Embodiment
The principle and feature of the present invention are described below in conjunction with accompanying drawing, the given examples are served only to explain the present invention, and
It is non-to be used to limit the scope of the present invention.
Fig. 1 is the flow chart of the refrigerator management method based on fingerprint recognition described in the embodiment of the present invention one.
As shown in figure 1, a kind of refrigerator management method based on fingerprint recognition, comprises the following steps：
Step S1, obtain user fingerprints information.
In the present invention can by the display and control panel of refrigerator set using locking/solving locking key of fingerprint identification technology come
User fingerprints information is obtained, at present fingerprint identification technology relative maturity, and be widely used in the neck such as security protection, work attendance and gate inhibition
Domain, its major function are that the finger print information of people is identified into verification, and fingerprint identification technology cost is used in than relatively low
Field of household appliances will not cause cost pressure.The fingerprint recognition mode of fingerprint identification technology mainly has optical profile type, pressure sensitive, electric capacity
Formula, inductance type, heat-sensitive type etc., the present invention in locking/solving locking key preferably use photo-electric fingerprint recognition mode.Therefore, pass through
Locking/solving locking key obtains user fingerprints information and specifically includes following steps:
Step S11, the timing since when sensing that user presses locking/solving locking key.
Step S12, judges whether timing duration exceedes preset duration, if so, step S13 is then performed, if it is not, return to step
S11；Wherein preset duration can be set as needed.
Step S13, gather user fingerprints information.
Step S2, judge that user fingerprints information whether there is in pre-stored fingerprint information bank；If so, then according to user fingerprints
Information is called and shows user's last time refrigerator use information；Otherwise, pre-stored fingerprint information bank is arrived into user fingerprints information storage
In.
Wherein, judge that user fingerprints information whether there is the process in pre-stored fingerprint information bank to be calculated using fingerprint recognition
Method carries out the process of fingerprint matching, and algorithm for recognizing fingerprint specifically includes the finger in the user fingerprints information that will be collected in step S1
Print image carries out image segmentation, patterns calculating, image enhaucament, image binaryzation, image thinning, feature extraction and with prestoring
The process that finger print information in finger print information storehouse is matched.Wherein, advance finger print information storehouse is prestore one of refrigerator
Or multiple finger print informations.
User's last time refrigerator use information includes user's last time time of storage/access food, storage/access food in refrigerator
Image, the position and information such as storage/access duration, these information are shown on the display and control panel of refrigerator, to remind use
Family.
In step S2, when judging that user fingerprints information is not present in pre-stored fingerprint information bank, display and control panel can be reminded
Whether user, which needs, is stored finger print information, if desired, the finger print information storage of this user then is arrived into pre-stored fingerprint information
In storehouse.
Step S3, detection refrigerator doors open or close；When detecting that refrigerator doors are opened, to the food in refrigerator before storage/access
Thing is shot to obtain the first image；Or when detecting that refrigerator doors are closed, the food in refrigerator after storage/access is clapped
Take the photograph to obtain the second image.
While user opens refrigerator doors, the camera in refrigerator carries out first time shooting to the food in refrigerator,
While user's closing refrigerator door, the camera in refrigerator carries out second to the food in refrigerator and shot.
Step S4, image analysis processing is carried out to the first image and the second image, letter is used to generate this refrigerator of user
Breath.
By being contrasted to the first image and the second image, it can detect that user is to be put into food using image algorithm
Or what the food for taking out food and being put into or taking out is.According to the result of image analysis processing, this refrigerator of user
When use information includes the time of this storage/access food in refrigerator of user, the image of storage/access food, position and storage/access
Information, these information such as long are stored in refrigerator, so as to next time when user uses refrigerator in the aobvious control face of refrigerator
Shown on plate, to remind user.
Step S5, stored after this refrigerator use information is matched with user fingerprints information.Make in user next time
When with refrigerator, according to user fingerprints information, it is possible to recall this refrigerator use information of user.
Fig. 2 is the structure chart of the refrigerator management system based on fingerprint recognition described in the embodiment of the present invention two.
According to the above-mentioned refrigerator management method based on fingerprint recognition, after technical characteristic is corresponded, can obtain such as Fig. 2
