Problems solved by technology

However, this technology needs to be related to time, and it is not suitable for users who have not unlocked for a long time and have large facial deformation, such as short-term weight gain or weight loss.
At the same time, there is no uniform standard for the preset unlocking time between two intervals, which is not friendly to the ease of use of the system

Abstract

The invention discloses a face image updating method, a storage medium, electronic equipment and a vehicle. The face image updating method comprises the steps of collecting a to-be-recognized face image; evaluating the to-be-recognized face image to obtain a first quality score, and extracting features of the to-be-recognized face image to obtain first image features; obtaining pre-stored image features of the pre-stored standard face image; and determining whether to update the pre-stored image feature to the first image feature according to the first quality score, the first image feature and the pre-stored image feature. According to the face image updating method, the standard face image can be updated in real time, so that the influence of face variability on a face recognition system is reduced, and the accuracy and usability of face recognition are improved.

Description

technical field [0001] The invention relates to the technical field of image recognition, and in particular, to a face image updating method, a storage medium, an electronic device and a vehicle. Background technique [0002] At present, face recognition technology is more and more widely used in the automotive field, such as face unlocking system outside the car, driver fatigue detection in the car, driver identification, etc. In the application of face recognition technology, it is not only necessary to ensure the security of face recognition, but also to meet the ease of use of the face recognition system. Since the vehicle-mounted face unlocking system has a long service cycle, it is necessary to update the standard face features to avoid the occurrence of the variability of the face and the influence of factors such as light, age, fat and thinness. When the face images cannot be matched. [0003] In order to solve the above problem, a technology for updating standard ...
