Description

Technical Field

[0001] The present invention relates to the technical field of face recognition equipment, and in particular to a multi-angle face information collection device. Background Art

[0002] At present, when facial recognition technology is applied in the field of face-swiping door opening, one of the factors that affects the efficiency and accuracy of facial recognition is that there is a difference between the shooting angle of the face in the face photo to be compared and the sample picture. The greater the deviation of this angle, the lower the recognition accuracy.

[0003] Face recognition is a biometric technology that identifies people based on their facial features. It uses a camera or camcorder to capture images or video streams containing faces, and automatically detects and tracks faces in the images. It then performs a series of face-related technologies on the detected faces. It is also commonly called portrait recognition or facial recognition.

[0004] Generally, when a face recognition device is in use, the image presented when a person faces the face recognition device at different angles is different, which makes the recognized face image possibly incomplete, thus affecting the accuracy of subsequent feature extraction and recognition, and even causing the face detection algorithm to fail. Not only that, during the face recognition process, if people's faces keep shaking, it will affect the face recognition device's collection of face information, thereby reducing the accuracy of the face recognition device in recognizing the face and reducing the practicality of the face recognition device.

The driven rotating member 31 is arranged corresponding to the main driving rotating member 21, and the outer side surfaces of the driven rotating member 31 and the main driving rotating member 21 are wrapped with a rubber friction layer.
