Huawei M2221-FL (8 mm to 32 mm) is an intelligent camera used for face image checkpoints. It supports the development of a face image system with accurate recognition, fast snapshot, high efficiency and stability.
Face detection and snapshot is primarily based on computer vision. It integrates multiple technologies, such as image processing, pattern recognition, and deep learning. It can analyze masses of videos in real time, filter out useless data, and extract valuable information.
The dynamic face image algorithm designed for densely populated settings, entrances and exits, is used to detect, track, and optimize dynamic face images to implement optimal snapshot.
Huawei M2221-FL accurately captures dynamic face images that facilitate the public security, commercial and judicial industries transformation towards the intelligent era.
Based on its deep learning algorithm, the M2221-FL camera uses multidimensional feature recognition and negative sample learning to enable face detection in complex locations. For example, users wearing glasses or mouth masks, areas with strong backlights, and incorrect facial angles.
Select the optimal snapshot based on the facial detection and tracking algorithm of feature comparison and several factors such as angle, definition, and illumination. These attributes greatly reduce the number of repeated snapshots and save storage and computing resources.
Adjust exposure parameters in real time based on the ambient light to optimize the image quality of snapshot and improve the recognition accuracy of the backend.
