Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, 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 creative efforts fall within the protection scope of the present invention.

[0026] see figure 1 , is a schematic diagram of an embodiment of the imaging system with 3D biometric recognition function of the present invention. The imaging system includes a transmitter 101 , a first receiver 102 and a second receiver 103 . The transmitter 101 is used to emit infrared light to a target object, such as a human face; the first receiver 102 is used to receive the infrared light reflected by the target object. The second receiver 103 is used for...

Abstract

The invention discloses an imaging system with a 3D biometric function, comprising a lens group, a beam splitter, an emitter, a first receiver and a second receiver, wherein the beam splitter is usedfor reflecting a first light to the second receiver and transmitting a second light to the first receiver. The first light ray is visible light, the second light ray is infrared light, the emitter isan infrared emitter, the first receiver is an infrared receiving sensor, and the second receiver is a front camera sensor. Since the beam splitter is adopted, the imaging system can receive infrared light and visible light through one aperture, so that the aperture of the image system is reduced and the appearance is simple. Moreover, the imaging system of the invention adopts 3D biometric recognition technology, can recognize a stereoscopic structure including a face surface and 3D depth, and has high safety.

Description

technical field [0001] The invention relates to the field of biological identification and optical imaging, in particular to an imaging system with 3D biological identification function. Background technique [0002] With the development of chip technology, more and more products use biometric technology as a means of identification in people's daily life, such as smart phones, tablet computers and other mobile devices. Biometrics, also known as biometrics, is widely used in face recognition. However, most of the existing face recognition technologies are two-dimensional (2D) plane recognition, which cannot receive third-dimensional information in the physical world, such as size and depth, and has poor security. Contents of the invention [0003] In order to solve the problem of poor security in the prior art, it is necessary to provide an imaging system with 3D biometric recognition function with high security and reliability. [0004] One aspect of the present inventi...
