Description
Technical Field
[0001] The utility model relates to the technical field of access control cleaning, in particular to a fingerprint collection access control cleaning device. Background Art
[0002] Fingerprint access control, also known as fingerprint access control system, is a system that uses fingerprint recognition technology to achieve access control. When the user uses it for the first time, he needs to press his finger on the fingerprint reader, and the sensor will sense and collect the fingerprint image. After preprocessing, such as denoising, enhancement and contrast adjustment, the quality of the fingerprint image is improved. Then, feature points are extracted from the processed fingerprint image, such as the fingerprint's detailed lines, intersections and bifurcation points, etc. These feature points constitute the uniqueness of the fingerprint. Based on these feature points, a fingerprint feature template is generated through an algorithm or model and stored in the fingerprint database of the access control system. When the user needs to enter the access control area again, he only needs to place his finger flat on the collection window of the fingerprint collector. The system will also collect and preprocess the fingerprint image, extract the feature points, and compare it with the fingerprint feature template stored in the fingerprint database. If the similarity reaches a certain threshold, it can be determined that the fingerprint successfully matches the fingerprint template of a certain user, and the access control system will authenticate and open the access control.
[0003] In actual applications, the fingerprint collection access control system requires the user to place his finger on a specific transparent collection window for identification. However, when the surface of the user's finger is stained with grease or other substances, these residues can easily remain on the transparent window, causing contamination of the window. This contamination not only affects the transparency of the window, but may also affect the accuracy of fingerprint recognition. In order to ensure the cleanliness of the transparent window, it is usually necessary to use a towel, paper towel or other cleaning tools to wipe these residues. However, this traditional cleaning method has some obvious shortcomings. First, it requires additional preparation of cleaning items, which undoubtedly increases the complexity of using the access control system. Secondly, frequent cleaning work not only consumes time, but may also affect the user experience due to untimely cleaning. Especially in emergency situations or occasions where access control is used frequently, this cleaning method may become an obstacle to the use of access control, thereby reducing the efficiency of the access control system and affecting the overall safety and convenience.
