Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Referring to fig. 1 and 2, an embodiment of the present invention provides a new energy vehicle control method based on face recognition, which specifically includes the following steps:
the method comprises the following steps of (I) registering a face, wherein the face registration is mainly implemented when a user needs to register new face information on a vehicle, and specifically comprises the following steps:
step A1, triggering face recognition registration through a mobile phone APP: and downloading and installing the application program app of the vehicle enterprise where the vehicle is located on the mobile terminal, and prompting the information for face recognition registration after the application program enters. Step A2, guiding the user to take a face photo: after the user operates according to the prompt of the mobile terminal, the application program outputs a guide prompt, and after the user makes corresponding actions according to the guide prompt, the user face is shot and a face photo is generated.
And step A3, judging whether the collected face picture meets the registration requirement. The registration requirement can be determined according to actual requirements, for example, the collected face photos can completely and clearly reflect the five sense organs of the face. The mobile phone can determine whether the collected face photos completely contain the face five sense organs or not according to image feature extraction, and if so, the collected face photos are determined to meet the registration requirements.
When the judgment is "no", it goes back to step a2 to continue to guide the user to take a picture.
When the judgment is "yes", the process proceeds to step a 4.
In the step A4, the mobile phone APP prompts the user that the registration is successful, the collected face photos of the user are encrypted and uploaded to the cloud platform, and the step A4 enters the step A5 after the uploading is finished.
In the step A5, the cloud platform wakes up the vehicle, issues the picture and the user ID of the current user to the vehicle, and deletes the face image picture stored in the body after the picture is issued.
In step a6, the vehicle acquires and decrypts the photograph, and then associates the acquired face image with the acquired user ID.
In step a7, the vehicle stores the associated face image and user ID in a face library local to the vehicle, and the face registration process ends.
(II) face authentication vehicle account login:
in step a1, a face image acquisition device mounted on the vehicle performs face detection.
In step a2, the onboard processor determines whether the face image capture device detects a face.
When the judgment result is "no", the process goes back to step a1 to continue to execute the face image acquisition device to detect the face.
When the judgment is "yes", the process proceeds to step a 3.
In step a3, the onboard processor extracts image feature information from the real-time face image captured by the face image capture device, compares the extracted image feature information with a preset face image database pre-stored on the vehicle, and determines whether a preset face image consistent with the image features of the real-time face image exists in the preset face image database pre-stored. The preset face image database comprises a face image acquired from the cloud platform and a user ID related to the face image.
In step A4, it is determined whether the comparison is successful.
When the judgment is "yes", the process proceeds to step a 5.
When the judgment is "no", the process proceeds to step a 6.
In step a5, the vehicle processor prompts "face authentication is successful" through voice, sends a request for accessing the vehicle account to the cloud platform, and after logging in the target vehicle account, the vehicle processor automatically adjusts the seat position, the steering wheel position and/or the rearview mirror position of the vehicle according to the associated setting information recorded in the target vehicle account, and displays the specific privacy information carried in the target vehicle account.
In step a6, the vehicle processor prompts "face authentication failed" through voice and refuses to log in the vehicle account, the vehicle processor starts the account privacy protection function, and the vehicle processor jumps to step a7 after face authentication fails.
In step a7, the data related to the privacy information in the functions of online music, online video, face payment, etc. of the vehicle account information are all hidden and cannot be viewed and used.
The characteristic privacy information in this embodiment includes: and data related to privacy information in functions of online music, online video, face payment and the like under the current vehicle account.
The embodiments described above describe only some of the one or more embodiments of the present invention, but those skilled in the art will recognize that the invention can be embodied in many other forms without departing from the spirit or scope thereof. Accordingly, the present examples and embodiments are to be considered as illustrative and not restrictive, and various modifications and substitutions may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims.
