Problems solved by technology

[0006] The mobile terminal needs to be equipped with visible light camera equipment and infrared light camera equipment at the same time, which has high requirements on hardware. In order to realize the acquisition and face recognition under different ambient light conditions, the hardware cost will inevitably increase, and multiple camera equipment will be configured. It will make the volume of the mobile terminal larger, which will bring inconvenience to the user for carrying and operating the mobile terminal

Abstract

The invention discloses a face recognition method, device and mobile terminal, belonging to the field of biological feature recognition. The method includes: according to a preset collection rule, using a dual light sensing camera to obtain a visible light face image set; according to the preset collection rule, using the dual light sensing camera to obtain an infrared light face image set; judging whether the local end There is a face template image matching any face image in the visible light face image set and the infrared light face image set; when the local end exists, the face recognition is passed. The present invention uses dual light sensing cameras for face recognition, which can realize face image collection and face recognition under different ambient light conditions, improves the accuracy of face recognition, and does not require mobile terminals to be equipped with multiple cameras, saving The hardware space improves the cost performance and facilitates the user to carry and operate the mobile terminal.

Description

technical field [0001] The present invention relates to the field of biological feature recognition, in particular to a face recognition method, device and mobile terminal. Background technique [0002] With the development of terminal technology and biometric identification technology, more and more mobile terminals can apply face recognition technology to realize multiple functions such as screen unlocking, identity recognition, and login verification. When performing face recognition, the mobile terminal uses the configured camera equipment to collect face images in real time, and perform matching and recognition with pre-collected template images. When the collected face images match the template images, the verification is passed. [0003] However, face recognition will be affected by ambient light. In a dark or bright environment, the ambient light is different from the ambient light when the template image was collected in advance, which may easily cause the camera eq...
