Description

Technical Field

[0001] The utility model relates to the technical field of facial recognition, and more specifically to a facial recognition module device with touch-sensing wake-up function. Background Art

[0002] The binocular face recognition module is based on the principle of binocular recognition technology. Two cameras collect images to obtain two different plane images. The feature points on the two images are then marked. The depth information is calculated based on the principle of triangulation to form a three-dimensional image. The binocular face recognition module is equipped with a dual lens on the front, and an infrared lamp bead is arranged in the middle of the dual lens. The binocular face recognition module is installed inside the panel of the light-transmitting visible material of the lock. Some customers have special structural designs. When there is a large gap between the lens, infrared lamp bead and panel, when the infrared lamp bead is lit, the light is irradiated from the inside of the lock panel to the periphery of the lens, and refracted and reflected from the lens through the structure to the image sensor. This cross-lighting in the structure causes a halo to be generated at the edge of the final collected image. In order to adapt to this special structure, it is necessary to additionally paste compressible foam around the infrared lamp bead of the binocular face recognition module to solve the problem of structural cross-lighting. At the same time, the conventional face recognition module is used with a microwave radar sensing module. It is usually in power-off mode. When the microwave radar sensing module detects the presence of a person, the lock control receives the sensing trigger signal, then powers on the face recognition module, and then powers off after completing the corresponding operation.

[0003] When implementing the above scheme, microwave radar sensing modules are used to detect the presence of human bodies or moving target sensing scenarios. In actual use, microwave radar sensing modules have disadvantages such as high power consumption and high cost. A solution is proposed below to address the above problems. Utility Model Content
