Automobile safety system based on biometric feature recognition and application method thereof

Abstract

The invention relates to an automobile safety system based on biometric feature recognition and an application method of the automobile safety system. The system comprises an iris recognition module, a breath alcohol detection module, a locking module, a control module, a communication module and a man-machine interaction module, wherein the iris recognition module is used for collecting iris images of users and judging whether the users are the authorized users or not based on the iris images of the users; the breath alcohol detection module is used for detecting airflow breathed out by the users and judging whether the users are in the drunken state or not; the locking module is used for locking operation of mechanical devices; the control module is used for controlling opening and closing of the locking module through judgment on the user states, the communication module is used for transmitting user information with the outside; the man-machine interaction module is used for reminding the users through voice information. By means of the automobile safety system, the driver identity and drunk driving can be detected at the same time, and cheats in driving are avoided, and thus traffic safety is guaranteed.

Description

technical field [0001] The invention relates to an automobile safety system based on biometric feature identification and its use method, in particular to an iris recognition-based automobile safety system and its use method. Background technique [0002] One of the reasons why safety accidents often occur when drivers are drunk and driving. Drunk driving refers to the phenomenon that the driver's physiological function and psychological function are disordered when he is drunk, and the driving skill declines objectively. Drunkenness can affect the driver's attention, feeling, perception, thinking, judgment and movement. If you continue to drive a vehicle after being drunk, you will feel drowsy, drowsy, weak in limbs, inattention, decreased judgment ability, and even appear in a trance or instant memory loss, delayed or premature action, operation pause or improper correction time and other unsafe factors, Highly prone to road traffic accidents. However, drivers often can...

Problems solved by technology

But, this invention also has the following problems: on the one hand, when carrying out face scanning, the operator breathes in the breath alcohol analyzer equipment simultaneously, and this is that the face of scanning is to wear the breath alcohol analyzer, and stores in the database like this The face without the breath alcohol analyzer may not match well, resulting in poor recognition effect. Although it can be overcome by storing the face image of the operator wearing the breath alcohol analyzer in the recognition database, the database needs More data is stored, and the face image of the operator wearing the breath alcohol analyzer may cover the operator's facial features, resulting in misjudgment; Face, in order to avoid being shut down by the mechanical system, the drunk operator may use other non-drunk personnel to sit on the operating chair for alcohol identification, and the drunk operator puts his face between other non-drunk personnel and the face recognition collection device, thereby cheating system
