Description

Technical Field

[0001] The utility model relates to the technical field of computer vision devices, in particular to a head-mounted facial motion information capturing device. Background Art

[0002] Facial surface analysis and capture of human faces are important virtual interaction technology means in the fields of 3D game animation, film and television special effects, virtual social interaction, human-computer interaction, etc., and expression capture is usually performed through a wearable facial expression capture device. Most existing wearable facial expression capture devices are helmet-type, and a bracket is provided on the helmet to fix the camera. When the human body is engaged in intense activities such as jumping, since the camera is fixed on the helmet, the camera can follow the jump and remain relatively still with the person, thereby achieving a better shooting effect. However, the camera information collected by this head camera in the prior art is transmitted to the data processing module by wired means for processing.

[0003] For example, in the prior art, facial expression capture devices such as Patent Nos. CN2022230792156 and CN2022220619705 all have a camera module at a certain distance in front of the far end of the helmet. However, when this helmet is worn on the head, the weight of the camera module is far away from the front of the helmet, which causes the center of gravity of the entire device to be forward, which will inevitably make the front end of the head very heavy, greatly affecting the player's experience.
