Description

Technical Field

[0001] This utility model relates to the field of image recognition, specifically a face image recognition device. Background Technology

[0002] A facial image recognition device is an intelligent device based on biometric recognition technology. It can capture facial images or video streams through a camera, use algorithms to extract key facial features such as eye distance and nose bridge height, generate a unique feature code, and then compare it with a database template to complete identity verification. Its core functions cover three steps: acquisition, extraction, and verification. It can quickly output results and provide an intelligent solution for identity verification.

[0003] A search revealed a patent document with publication number CN114612975A, which discloses a mesh-pattern face image recognition device. The device includes a housing, the lower half of which is semi-cylindrical and the upper half hemispherical, and a base located below the housing. It also includes a recognition component and an adjustment component. The recognition component is located inside the housing and is used to recognize mesh-pattern faces. The adjustment component is located inside the housing and is used to adjust the position of the recognition component during operation. This invention solves the problem that existing face recognition devices are affected by weather changes, such as sunlight or low ambient light, leading to a decrease in the success rate of face recognition and a longer recognition time.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: the lack of protective components makes core components such as cameras and sensors susceptible to collisions and scratches, or hardware failures caused by dust and rainwater intrusion, thus shortening the lifespan of the equipment. Therefore, a face image recognition device is proposed to address these issues. Utility Model Content
