With the rapid development of intelligent technology industry, biometrics has become an advanced technology to verify “people” in this era. And face recognition is the most concerned in many biotechnology. Face recognition is divided into monocular and binocular. What is the difference? What are their respective advantages? Today, Xiaojin will take you to understand the knowledge points of face recognition:
Monocular camera
Definition of monocular camera: analyze real-time unstructured video data into structured data through monocular algorithm, judge whether there is a face in the input face image or video based on human facial features, then capture the location of key facial information, analyze and obtain gender, age and other attributes, which can be used for accurate promotion; It can acquire expressions in real time, and can be used for expression interaction or customer sentiment analysis. Through monocular RGB live detection, supported face database search (1: N), and 1:1 comparison between myself and ID photos.
Advantages: easy deployment, low cost Applicable scenarios: accurate promotion, passenger flow statistics, access control management and other applicable equipment: fitting mirror (magic mirror), intelligent shelf, face recognition attendance machine, self-service equipment, etc.
Binocular camera
Definition of binocular camera: a face recognition solution based on binocular cameras. This solution uses binocular cameras. The binocular camera module uses infrared light compensation technology, and has the video capture function of near-infrared light and visible light. Based on the infrared imaging principle, screen type images cannot be formed, which can effectively filter screen type attacks. Paper can be used for living recognition of IR image texture, color and other features. In this way, we can effectively prevent counterfeiting fraud such as plane photos and videos, accurately detect whether they are “living people”, and ensure the accuracy of living detection. Compared with monocular camera plane vision technology, it has higher detection accuracy and faster processing speed.
Advantages: Compared with the monocular face recognition solution, the binocular face recognition solution has higher accuracy in living detection, can effectively resist attacks from photos, videos, etc., and is more adaptive to light changes, complex background environment and other factors, which can support real unattended. Applicable scenario: applicable equipment for access control management: face recognition gate, face recognition attendance machine, etc.
Monocular VS Binocular
The monocular camera is mainly a visible camera, and the binocular camera is composed of a visible camera and an infrared camera. Monocular is mainly used for non living body detection. Of course, depending on the algorithm of face recognition, it is possible to achieve monocular living body detection. However, in living body detection, binocular detection is still the main method. The binocular living body is more rigorous than the monocular living body, and the probability of being cracked is much smaller.
Future development trend
The research on face recognition technology in China has developed rapidly in recent years, and has formed a trend of branding. It is on a par with foreign technologies. The face recognition technology in China has been used commercially in security, finance and other fields. With the gradual maturity of mainstream face technology, further development will be achieved in the future in terms of improving the quality of face images, 3D face image applications, deep learning based face recognition technology applications, and more diversified and universal face image database construction.
