What is the principle of iris attendance machine? Iris recognition attendance machine working principle is what kind of process? Iris recognition attendance machine is a relatively high-end attendance management machine, with the most advanced biological recognition technology - iris recognition, so the use of fingerprint and face attendance more accurate, then the work of the iris attendance machine is based on what kind of technology Principle? This article provides a detailed analysis of the specific work flow of iris attendance.
The iris recognition attendance machine is based on iris recognition. The iris is one of the human biological characteristics. It has the unique characteristics as the fingerprint. Compared with the features that the fingerprint is easy to be flattened and deformed, the iris is more stable and therefore more accurate in recognition.
We all know that the important part of the human eye is the iris. The iris is located in front of the vascular membrane. It automatically adjusts the size of the pupil and adjusts the light exposure.
Iris recognition technology is based on the identification of the iris in the eyeball. It has been widely used in security equipment and other industries.
The technical basis of iris recognition: The human eye structure consists of the retina, sclera, iris, pupil lens and other parts. The iris is an annular portion between the black pupil and the white sclera. It is characterized by a large number of detailed features such as spots, filaments, coronal, stripes, crypts, etc. that are interlaced. Each person has a different iris structure. In addition, the iris is almost stable throughout the entire life cycle after the fetus has developed. These excellent qualities determine the biological uniqueness of iris features and are the technical basis for the uniqueness of identity.
Therefore, iris recognition, as an emerging technology, has been promoted and also has advantages that are difficult to compare with other biometric technologies.
Iris recognition attendance machine working technology principle process analysisThe working principle of iris recognition attendance machine is similar to other biometric attendance machines. It uses biometrics to match and identify, but it only replaces the identification medium with the human iris. The workflow is as follows:
1, the iris attendance machine collects and records the staff's iris information, and carries on the number archive, as the original reference data, completes the database creation process.
2. The employee and the face recognition attendance machine keep a certain distance, aim the eyes at the camera and complete the blinking movement as required.
3, the iris attendance camera captures the iris image information in the eye and verifies the captured iris features with the information in the database.
4. The recognition is successful. If the data is consistent with the database information, the attendance passes. If the recognition fails, it may not be entered or operated improperly.
5. After the attendance is completed, the iris attendance machine will successfully record the information and replace the newly captured iris image with the existing image as new reference information.
The above is a detailed description of the intelligent attendance machine identification technology basis and working principle flow of the smart lock China net Xiaobian finishing publishing. For more information, please pay attention to the related column content of this site!
