The auto face tracking phone holder achieves 360° rotating face and body tracking, mainly relying on advanced face tracking technology and precise mechanical structure design.1. Face tracking technologyFacial recognition and tracking: The auto face tracking phone holder has a built-in high-precision facial recognition algorithm. When the holder is turned on and connected to the mobile phone, the algorithm captures and analyzes the face information in the video or image sequence in real time.Once the face is detected, the algorithm will continue to track the position, size and possible expression changes of the face to ensure that the mobile phone camera is always aimed at the user's face.Multiple tracking methods: Model-based tracking: By obtaining prior knowledge of the face, a low-cost parameter model (such as skin color model, ellipse model, etc.) is established, and each frame of the input image is matched with the model to achieve face recognition and tracking.Tracking based on motion information: The continuity of the target motion between consecutive frames of the image is used to predict and track the face area. Common methods include optical flow method, Kalman filter, etc.Based on local facial feature tracking: Tracking is performed based on local facial features (such as eyes, nose, mouth, etc.). This type of method is usually combined with feature point tracking technology to achieve accurate face tracking.Based on deep learning tracking: Use deep learning models (such as Siamese networks, DeepSORT, etc.) to learn the feature representation and motion pattern of the face to achieve efficient and robust face tracking.2. Mechanical structure designRotation mechanism: The rotation mechanism of the auto face tracking phone holder is exquisitely designed to support 360° rotation without dead angles. This is usually achieved through motor drive and precision gear transmission system.When the face tracking algorithm detects a change in the position of the face, the rotation mechanism will respond quickly and adjust the angle of the mobile phone camera to ensure that it is always aimed at the user's face.Stabilization system: In order to ensure the stability of the mobile phone camera during shooting, the auto face tracking phone holder is usually equipped with a stabilization system. This can be a physical stabilizer (such as a tripod, gimbal, etc.) or a software stabilization algorithm (such as electronic image stabilization).The physical stabilizer reduces the impact of external interference on shooting through a solid structure and a precise adjustment mechanism. The software stabilization algorithm compensates for the slight shaking of the camera through image processing technology.Adaptive adjustment: Some advanced auto face tracking phone holders also have adaptive adjustment functions. They can automatically adjust the height and angle of the camera according to factors such as the user's height, sitting or standing posture to ensure the best shooting effect.3. Comprehensive applicationIn actual applications, auto face tracking phone holders are usually used in conjunction with mobile phone APP or professional shooting software. Users only need to install the mobile phone on the holder and start the corresponding software to achieve automatic face tracking and intelligent shooting. This holder is particularly suitable for scenes such as real-time Vlog streaming video, online teaching, and remote meetings, which can greatly improve shooting efficiency and video quality.In summary, the auto face tracking phone holder realizes the function of 360° rotating face and body tracking through advanced face tracking technology and precise mechanical structure design. This technology not only improves the convenience and efficiency of shooting, but also brings users a more natural and intelligent shooting experience.
