Problems solved by technology

However, the existing face recognition methods often use relatively large and complex algorithm models in order to obtain high accuracy in harsh environments (such as uneven illumination, occlusion, etc.), which not only takes up a lot of system resources but also The calculation speed is also slow, so it is difficult to apply to the requirements of the face recognition system in the vehicle environment

Abstract

The invention provides a driver face recognition method, system and device and a medium. The method comprises: acquiring a face image of a driver; extracting a face recognition area from the face image, and adjusting the face recognition area to meet a preset recognition condition; inputting the face recognition area into a trained face feature extraction model constructed based on deep learning to obtain a face feature vector; calculating similarity according to a face feature vector output by the face feature extraction model and a face feature vector of a pre-stored image; and if the similarity is greater than a specified threshold, judging that the face is the face of the same person, and if the similarity of a plurality of pre-stored face images is greater than the threshold, judgingthat the pre-stored face image with the maximum similarity and the face image of the driver are the face images of the same person, thereby determining the identity of the driver. The method has the advantages of being high in speed, high in recognition accuracy and good in algorithm robustness, and therefore the requirement for vehicle-mounted face recognition is met.

Description

technical field [0001] The present invention relates to the technical field of vehicle control, in particular to a driver face recognition method, system, device and medium. Background technique [0002] Face recognition is a biometric technology for identification based on human facial feature information. The basic principle and process of the face recognition system are: use a video camera or a camera to collect images containing faces of users, extract the feature vectors of the face images, and then compare the extracted feature vectors with the feature vectors corresponding to the photos in the database. Calculation of similarity; if the calculated similarity is higher than the specified threshold, it can be determined that the collected face image is a face image in the database, and then the identity of the user can be determined. [0003] In recent years, face recognition technology has been applied to community access control systems, attendance systems, anti-thef...
