Detailed Description
An embodiment of the door lock lubrication degree level collection mechanism of the present invention will be described in detail below with reference to the accompanying drawings.
Fingerprint scanning has two basic tasks: one is to obtain an image of the finger and the other is to determine whether the fingerprint in the image matches the fingerprint in the previously scanned image.
There are several methods for obtaining an image of a person's fingerprint, the most common being optical scanning and capacitive scanning, both of which work in completely different ways but both of which will obtain the same image.
The core component of optical scanning is a Charge Coupled Device (CCD), which is the same as the photosensor systems used in digital cameras and video cameras. A CCD is simply a set of photodiodes that produce an electrical signal under the influence of photons. Each photosensitive device records a pixel, a tiny dot representing the beam striking that point. The light and dark images together constitute an image of the scanned scene.
Typically, in a fingerprint scanning system there is an analog-to-digital converter that processes analog electronic signals to produce a digital representation of the image.
In order to overcome the defects, the invention builds a mechanism for acquiring the degree of lubrication of the door lock, and can effectively solve the corresponding technical problem.
