Problems solved by technology

[0003] For existing face recognition systems, illumination changes are a major factor affecting system recognition performance. When the illumination during recognition is inconsistent with the illumination conditions during user registration, it usually causes a significant decline in recognition performance; and in some Under special circumstances, the recognition device in the recognition system may be irradiated by strong light such as sunlight, resulting in the recognition device not receiving any lighting information fed back from the face in this case, which greatly affects the recognition performance of the face recognition system
[0004] Aiming at the problem that the existing face recognition system has poor recognition performance under strong light, no effective solution has been proposed so far

Abstract

The present invention provides a face recognition method and device, wherein the method includes: acquiring the reflection signal of the face of the target recognition object; wherein the reflection signal includes an optical signal and an ultrasonic signal; performing feature extraction processing on the reflection signal to generate a face The actual feature data; compare the actual feature data with the ideal feature data in the pre-established feature database to confirm the identity information of the target identification object; wherein, the feature database includes the identity information of the specified user and the ideal feature corresponding to the identity information data; the ideal feature data includes optical feature data and ultrasonic feature data corresponding to the specified user's face. By combining the optical signal and the ultrasonic signal, the present invention can extract the characteristic data of the target identification object through the ultrasonic signal when the optical signal is weak when the strong light is irradiated, so as to realize all-weather face recognition and improve the face recognition. The environmental adaptability of the identification method.

Description

technical field [0001] The present invention relates to the technical field of face recognition, in particular to a face recognition method and device. Background technique [0002] Face recognition is a biometric technology for identification based on human facial feature information; face recognition technology usually uses cameras or cameras to collect images or video streams containing faces, and automatically detects and tracks people in the images face, and then perform a series of face-related processing on the detected face. [0003] For existing face recognition systems, illumination changes are a major factor affecting system recognition performance. When the illumination during recognition is inconsistent with the illumination conditions during user registration, it usually causes a significant decline in recognition performance; and in some Under special circumstances, the recognition device in the recognition system may be irradiated by strong light such as sun...
