Fig. 2 is the structure chart based on the refrigerator management system of fingerprint recognition described in the embodiment of the present invention two.
Detailed description of the invention
Be described principle of the present invention and feature below in conjunction with accompanying drawing, example, only for explaining the present invention, is not intended to limit scope of the present invention.
Fig. 1 for described in the embodiment of the present invention one based on the flow chart of the refrigerator management method of fingerprint recognition.
As shown in Figure 1, a kind of refrigerator management method based on fingerprint recognition, comprises the steps:
Step S1, obtains user fingerprints information.
The locking/unlocking key of fingerprint identification technology can be adopted to obtain user fingerprints information by arranging on the display and control panel of refrigerator in the present invention, current fingerprint identification technology relative maturity, and be widely used in the fields such as security protection, work attendance and gate inhibition, its major function the finger print information of people is carried out identification check, and fingerprint identification technology cost is lower, is used in field of household appliances and can not causes cost pressure.The fingerprint recognition mode of fingerprint identification technology mainly contains optical profile type, pressure sensitive, condenser type, inductance type, heat-sensitive type etc., and the locking/unlocking key in the present invention preferably adopts photo-electric fingerprint recognition mode.Therefore, obtain user fingerprints information by locking/unlocking key specifically to comprise the following steps:
Step S11, timing from when sensing that user presses locking/unlocking key.
Step S12, judges whether timing duration exceedes preset duration, if so, then performs step S13, if not, returns step S11; Wherein preset duration can set as required.
Step S13, gathers user fingerprints information.
Step S2, judges whether user fingerprints information is present in pre-stored fingerprint information bank; If so, then call according to user fingerprints information and show the last refrigerator of user and use information; Otherwise, user fingerprints information is stored in pre-stored fingerprint information bank.
Wherein, judge that the user fingerprints information process whether be present in pre-stored fingerprint information bank is use algorithm for recognizing fingerprint to carry out the process of fingerprint matching, algorithm for recognizing fingerprint specifically comprises and the fingerprint image in the user fingerprints information collected in step S1 is carried out Iamge Segmentation, patterns calculating, image enhaucament, image binaryzation, image thinning, feature extraction and carry out the process of mating with the finger print information in pre-stored fingerprint information bank.Wherein, finger print information storehouse is one or more finger print informations that refrigerator prestores in advance.
The last refrigerator of user uses information to comprise time of the last storage/access food in refrigerator of user, the image of storage/access food, position and the information such as storage/access duration, and these information are all presented on the display and control panel of refrigerator, in order to reminding user.
In step S2, when judging that user fingerprints information is not present in pre-stored fingerprint information bank, display and control panel can store the need of by finger print information by reminding user, if desired, is then stored in pre-stored fingerprint information bank by the finger print information of this user.
Step S3, detects refrigerator doors and opens or closes; When detecting that refrigerator doors is opened, shooting being carried out to the food in refrigerator before storage/access and obtains the first image; Or, when detecting that refrigerator doors is closed, shooting being carried out to the food in refrigerator after storage/access and obtains the second image.
While user opens refrigerator doors, the camera in refrigerator carries out first time shooting to the food in refrigerator, and while user's closing refrigerator door, the camera in refrigerator carries out second time shooting to the food in refrigerator.
Step S4, carries out image analysis processing to the first image and the second image, uses information to generate this refrigerator of user.
By contrasting the first image and the second image, user puts into food or takes out food and what the food putting into or take out is to adopt image algorithm to detect.According to the result of image analysis processing, this refrigerator of user uses information to comprise time of this storage/access food in refrigerator of user, the image of storage/access food, position and the information such as storage/access duration, these information are all stored in refrigerator, to show on the display and control panel of refrigerator when user uses refrigerator, with reminding user next time.
Step S5, stores after this refrigerator is used information and user fingerprints information matches.Upper in once user uses refrigerator, according to user fingerprints information, just can recall this refrigerator of user and use information.
Fig. 2 is the structure chart based on the refrigerator management system of fingerprint recognition described in the embodiment of the present invention two.
