Problems solved by technology

[0005] The present invention is to provide a camera supplementary light system and method for improving the accuracy of face recognition. The main technical problem to be solved is: when the light is dark, the existing camera needs to use infrared LED lamps for supplementary light to obtain clear images. Human face, but it takes a lot of energy to light up the infrared LED, which will cause a lot of heat generated by the LED lamp, which will affect the ambient temperature of the camera and shorten the service life of the camera. At the same time, the use of a dedicated face recognition sensor IC will cause face recognition The camera system costs more

Embodiment Construction

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Apparently, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0028] The specific implementation mode in this embodiment is described by taking the central control panel as an example in the accompanying drawings of the specification, that is, adjusting the backlight brightness of the central control panel to adjust the brightness of the ambient light, but the camera supplementary light system and camera supplementary light method of this embodiment , the backlight of the light-emitting modules in the car such as the central control...

Abstract

The invention relates to the technical field of camera face recognition, in particular to a camera light supplementing system and method capable of improving face recognition accuracy, the system comprises an environment brightness adjusting module (10), a face recognition control module (20) and a camera module (30), and the environment brightness adjusting module (10) and the camera module (30)are respectively in bidirectional communication connection with the face recognition control module (20). According to the invention, the problems that when the light ray of the existing camera is relatively dark, an infrared LED lamp needs to be adopted for supplementing light to obtain a clear face; however, a large amount of energy is needed to turn on the infrared LED, the heating value of anLED lamp is large, the environment temperature of the camera is influenced, the service life of the camera is shortened, and meanwhile, a special face recognition sensor IC is adopted, so that the cost of a face recognition camera system is high are solved.

Description

technical field [0001] The invention relates to the technical field of camera face recognition, in particular to a camera light supplement system and method for improving the accuracy of face recognition. Background technique [0002] Camera refers to a device with basic functions such as video recording / communication and static image capture. After the image is collected by the lens, the image is processed by the photosensitive component circuit and control component in the camera, and converted into a computer that can recognize it. The digital signal is input to the computer through the parallel port or USB connection, and then the image is restored by the software. [0003] Face recognition is a popular computer technology research field. It belongs to biometric identification technology, which is to distinguish individual organisms by their own biological characteristics. The face recognition system mainly includes four components: face image acquisition and detection,...
