The intelligent lock comprises an intelligent lock 10, a fingerprint acquisition module 11, a guide module 12, a main control module 13 and a storage module 14.
Detailed Description
The invention is described in detail below with reference to the figures and the embodiments.
As shown in fig. 1 and 2, the present invention discloses an intelligent lock and a fingerprint collection method thereof. Wherein, an intelligence lock 10 contains: fingerprint acquisition module 11, guide module 12, host system 13 and storage module 14. Wherein: the fingerprint acquisition module 11 is used for acquiring a fingerprint image of a user. The guiding module 12 is used for guiding the user to press and move the same finger to acquire sub-fingerprint images of different positions of the same finger of the user, and guiding the user to perform operation. The guiding module 12 may be a voice prompt, may be a voice prompt and panel key backlight guiding together, and may also be a voice prompt, panel key backlight guiding and APP registration interface guiding together. The main control module 13 is used for controlling the intelligent lock 10. The storage module 14 is configured to store a plurality of sub-fingerprint images. Specifically, the guiding module 12 guides the user to press and move the same finger to capture sub-fingerprint images of five positions including the center position, the upper position, the lower position, the left position and the right position of the same finger of the user, and the finger of the user keeps in contact with the fingerprint capturing module 11 in the process, i.e. does not separate from the fingerprint capturing module 11, and only rotates or moves the finger without lifting the finger when capturing the fingerprint image.
The scheme also provides a fingerprint acquisition method for the intelligent lock 10, which comprises the following steps:
a user's finger is placed in the fingerprint collection module 1111 to collect a sub-fingerprint image through the fingerprint collection module 1111.
The user is guided to press and move the same finger through the guiding module 12 so as to acquire sub-fingerprint images of different positions of the same finger of the user. In the process, when the guide module 12 guides the user to operate, the finger does not separate from the fingerprint acquisition module 11, and only the finger is rotated or moved without lifting the finger when the fingerprint image is acquired;
the plurality of sub-fingerprint images acquired by the fingerprint acquisition module 11 are stored in the storage module 14.
The specific method for guiding the user to press and move the same finger to collect the sub-fingerprint images of different positions of the same finger of the user comprises the following steps:
the guide module 12 guides the user to press and move the same finger so as to acquire sub-fingerprint images of five positions including the center position, the upper side position, the lower side position, the left side position and the right side position of the same finger of the user. That is, the sub-fingerprint information of multiple parts of the finger of the user can be collected by guiding the user to press and move the same finger through the guiding module 12, and the finger does not depart from the fingerprint collecting module 11, so that the finger fingerprint information is consistent and comprehensive.
According to the intelligent lock 10 and the fingerprint collection method thereof, the user is guided to press and move the same finger so as to collect sub-fingerprint images of different positions of the same finger of the user and store the sub-fingerprint images. Therefore, the fingerprint information of all parts of the same finger can be collected when the fingerprint of the finger is registered, and the fingerprint is coherent and comprehensive. When a fingerprint is identified, the fingerprint information randomly acquired by the fingerprint acquisition module 11 is compared with the fingerprint information containing all parts, so that the success is easier to obtain, and the false rejection rate or the identification failure rate is reduced.
Further, a specific method for guiding the user to press and move the same finger to acquire the sub-fingerprint images of five positions including the center position, the upper side position, the lower side position, the left side position and the right side position of the same finger of the user is as follows:
the guiding module 12 guides the user to press the center position of the finger on the collecting area of the fingerprint collecting module 11, and then the center sub-fingerprint image of the center position of the finger is collected through the fingerprint collecting module 11;
the guiding module 12 guides the user to press the moving finger so that the upper side position of the finger is pressed on the collecting area of the fingerprint collecting module 11, and then the upper side sub-fingerprint image of the upper side position of the finger is collected through the fingerprint collecting module 11;
the guiding module 12 guides the user to press the moving finger so that the lower side position of the finger is pressed on the collecting area of the fingerprint collecting module 11, and then the lower side sub-fingerprint image of the lower side position of the finger is collected through the fingerprint collecting module 11;
the guiding module 12 guides the user to press the moving finger so that the left position of the finger is pressed in the collecting area of the fingerprint collecting module 11, and then the left sub-fingerprint image of the left position of the finger is collected through the fingerprint collecting module 11;
the guiding module 12 guides the user to press the moving finger so that the right position of the finger is pressed on the collecting area of the fingerprint collecting module 11, and then the right sub-fingerprint image of the right position of the finger is collected through the fingerprint collecting module 11.
As a specific implementation manner, in the process of pressing the moving finger, the fingerprint acquisition module 11 determines whether the finger of the user moves to a specified position according to the detected pressing information, and performs fingerprint acquisition on the fingerprint at the specified position if the finger moves to the specified position. In the process of pressing the mobile finger, the fingerprint acquisition module 11 determines whether the finger of the user leaves the acquisition area of the fingerprint acquisition module 11 according to the pressing information detected by the fingerprint acquisition module 11, and if the finger leaves the acquisition area, the registration fails, that is, the fingerprint acquisition module 11 detects whether the finger is separated from the fingerprint acquisition module 11 in the process of acquiring the fingerprint.
Further, after the fingerprint acquisition module 11 acquires the sub-fingerprint image, the main control module 13 further determines whether the sub-fingerprint image meets the standard. The standard here means that the area of the acquired fingerprint image is larger than a preset area. That is, after the central sub-fingerprint image is collected, the main control module 13 determines whether the central sub-fingerprint image is larger than a preset area, and if the central sub-fingerprint image is larger than the preset area, the central sub-fingerprint image meets the standard.
Furthermore, after the central sub-fingerprint image is acquired, the main control module 13 first determines whether the user is an adult or a child. Since the curvatures of the fingerprints of the fingers of the adult and the child are different, the main control module 13 can judge whether the finger is the adult or the child according to the preset curvature of the fingerprint. For example, if the curvature of the fingerprint is greater than a predetermined value, it can be determined as an adult, and if the curvature of the fingerprint is less than the predetermined value, it can be determined as a child. If the user is an adult, judging whether the central sub-fingerprint image is larger than a first preset area, and if the central sub-fingerprint image is larger than the first preset area, enabling the central sub-fingerprint image to accord with the standard. If the user is a child, judging whether the central sub-fingerprint image is larger than a second preset area, wherein the second preset area is smaller than the first preset area, and if the central sub-fingerprint image is larger than the second preset area, the central sub-fingerprint image meets the standard. This means that the verification of the smart lock 10 is made more accurate and more easily successful, which further reduces the rate of false negatives or identification failures.
As a specific implementation manner, a specific method for storing a plurality of sub-fingerprint images is as follows: and processing the plurality of sub-fingerprint images into a finished fingerprint image and storing the finished fingerprint image. Therefore, the comprehensiveness and integrity of the fingerprint information of the same finger of the user can be ensured.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It should be understood by those skilled in the art that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by using equivalent alternatives or equivalent variations fall within the scope of the present invention.
