Description

Face recognition camera component in the car

Technical field

The invention relates to the field of biosign recognition in a vehicle, and in particular to a camera assembly for face recognition in a vehicle.

Background technique

Face recognition (Human Face Recognition), also commonly called face recognition and face recognition, is a kind of biometrics recognition technology based on human facial feature information. A series of related technologies that use cameras or cameras to collect images or video streams containing human faces, and automatically detect and track human faces in images, and then recognize the detected human faces.

At present, face recognition has entered into various products, especially in the automotive field. E.g:

When the driver enters the car and powers on, the face recognition system recognizes who the driver is and enters the driver. After recognition, the system will automatically adjust the seat according to the driver's previous settings and play the driver's favorite music. It is worth mentioning that the system can recognize up to five drivers and remember these preferences of different drivers.

The face recognition function can first play a role in assisting safety, which can recognize whether the driver is in a fatigued driving state and is too distracted.

In addition to driving safety, the face recognition function can also be used to protect the vehicle's property safety and payment security. When the system recognizes that an unregistered suspicious person has boarded the vehicle, it can trigger an alarm in the cloud and synchronize the suspicious person’s face information to the cloud, while payment security refers to the use of face recognition for quick payment verification.

In addition, the facial recognition technology on the vehicle can also be integrated with the user's account. After the driver's facial recognition through the camera in the car and the creation of an exclusive ID, the vehicle can store the driver's behavior preferences and historical trajectory. After the vehicle recognizes that the driver has entered the vehicle, it can adjust the seat and rearview mirror to its most comfortable state according to the user’s information stored in the cloud, play her favorite song for it, and according to the time, LBS Location and other information to determine the navigation destination.

The structure of the existing face recognition camera module in the car, the camera lens and the infrared lens are exposed outside the module. Although this structure can ensure that the camera is not blocked, it will sacrifice the shape of the vehicle's interior, which is not conducive to the overall appearance of the vehicle. Moreover, the exposed camera will have dust in it, which is not conducive to cleaning after a long time.

In view of this, the present invention provides an in-vehicle face recognition camera assembly.

detailed description

Example embodiments will now be described more fully with reference to the drawings. However, the example embodiments can be implemented in various forms and should not be construed as being limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be comprehensive and complete, and the concept of example embodiments will be fully communicated to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus their repeated description will be omitted.

FIG. 1 is a schematic diagram of a face recognition camera assembly in a vehicle of the present invention. 2 is a cross-sectional view of a face recognition camera assembly in a vehicle of the present invention. FIG. 3 is a schematic diagram of an in-vehicle face recognition camera assembly after removing an infrared filter cover. 4 is a cross-sectional view of an in-vehicle face recognition camera assembly after removing an infrared filter cover.
