Driver identity authentication method for school bus safety

Abstract

The invention discloses a driver identity authentication method for school bus safety. The driver identify authentication method comprises steps of arranging a filter in the front of a lens of a camera for filtering visible light, adopting an infrared light source to effectively eliminate the interference caused by the environment light, performing human face key point detection on the infrared image, performing face image processing based on the positions of the key points to obtain a front formalized human face so as to eliminate the interferences caused by postures, sizes and positions, constructing a grey vector to calculate the Jaccard similarity on the basis of the formalized image, and performing fast human face comparison to realize driver identity authentication. Adoption of the grey level can fast and effectively describe face characteristics, and calculation of the Jaccard coefficient similarity based on the grey vector is simple and fast without need of substantial samples for training, and is applicable to a school bus management operation mode.

Description

technical field [0001] The invention relates to a driver identity authentication method for school bus safety. Background technique [0002] In recent years, school bus safety has attracted increasing attention from the whole society. The government has issued relevant laws and regulations to strengthen school bus management, among which the qualification review and identity authentication of drivers is one of the important links. On April 5, 2012, the State Council promulgated and implemented the "Regulations on School Bus Safety Management", which made specific regulations on the qualifications of school bus drivers. However, in the actual operation of the school bus, there is still a lack of effective authentication of the driver's identity, and there are situations where unauthorized school bus drivers drive instead, which poses a major safety hazard. [0003] There are two main types of existing driver identity authentication methods. The first type, such as the method...

However, in the actual operation of the school bus, there is still a lack of effective authentication of the driver's identity, and there are situations where unauthorized school bus drivers drive on behalf of them, posing a major safety hazard

[0003] There are two main types of existing driver identity authentication methods. The first type, such as the methods described in patents such as CN201220362617, uses card readers such as RFID card readers and ID card readers to obtain driver identity information for verification. The separability of the card and the personnel, this type of method can not really realize the driver identity authentication; the second type is the method of comparing the face of the driver with visible light based on the live video or image, such as patents CN201220390464, CN201310096618, etc., here This type of method can perform on-site authentication of the driver's identity, but due to the diversity of the on-site environment and the deflection of the driver's posture in an unnatural working state, the existing identity authentication method based on face comparison is vulnerable to light and posture. Influenced by other factors, the accuracy rate is low, and it has not been applied on a large scale.
