As the name implies, there are two cameras, just like two eyes of a human being. One camera collects visible light photos, and the other camera collects near and external light photos, and recognizes the received face. It accurately identifies and locates some key characteristic points such as eyes, mouth, ears, nose, and calculates the spatial distance information of the face as the verification condition. The pupil distance, nose height, eye mouth ear distance, etc., The error of the result is less than 1mm, which is why the living body recognition can effectively resist attacks and frauds such as photos and videos, accurately detect, and ensure the accuracy of the living body detection.
Its advantage is that compared with the monocular face recognition access control terminal solution, the binocular face recognition access control terminal solution can obtain higher accuracy in the aspect of live detection. In addition to effectively resisting attacks such as photos and videos, it is also more adaptable to light, complex background environment, etc., and can be truly unattended. Por lo tanto, it is more suitable for some access control management scenarios, which are installed on the face recognition gate as doorkeepers.
So what should we pay attention to when designing a binocular face recognition camera? Today, Xiaojin brings you to understand:
1. Design principle of binocular camera
The binocular detection method is to directly measure the distance of the front scene by calculating the visual difference between two images. There is no need to judge what type of obstacle appears ahead. This is just like our eyes. The reason why we can feel the distance between objects and us is that there are two eyes imaging the same object separately. The difference between the two resulting pictures. In binocular design, the two lenses need to be on the same plane, and different light compensation is required for the lens. The distance between the two lenses should not be too close to avoid interference angle imaging.
2. Appearance design of binocular camera
The binocular camera can give necessary warning or braking for any type of obstacle according to the change of distance information. In addition to the application in intelligent access control and other security devices, the product can also be used in unmanned driving, safety early warning, active protection and other safe driving. Por lo tanto, in the appearance design of binocular cameras, it is necessary to strive for simplicity and high-end according to different application scenarios to achieve the highest level of security protection.
3. Structure design of binocular camera
The binocular camera takes into account the image processing and algorithm of two lenses, so the cost is high and the heat is large, but the product space is limited, which brings some difficulties to the structural design of the binocular camera. How to achieve the balance of cost control, protection level, heat dissipation requirements, shockproof and other factors requires experienced camera module and lens suppliers and structural engineers to grasp.
