Mark-point-free face capturing device and method

Abstract

The invention provides a mark-point-free face capturing device and method. The device comprises a surface capture helmet, a computer and a mobile device, the computer comprises UE engine software, wherein the face capture helmet is used for shooting a face video and sending the face video to the computer for display, and the mobile device is used for capturing the face video displayed by the computer to obtain facial expressions, generating expression animations of virtual character roles and transmitting the expression animations to the UE engine software. High-standard face capture precisioncan be achieved under the condition that no mark point exists, and meanwhile the device is easy to operate and good in stability.

Description

technical field [0001] The invention belongs to the field of film and television animation AR face capture, and in particular relates to a marker-free face capture device and method. Background technique [0002] The production of facial expressions occupies a very important position in 3D production, so the production technology of facial expressions is also constantly developing. Due to the more and more frequent application of 3D special effects and film and television animation, animation production requires a lot of time. The traditional animation production method is manual adjustment by animators. To achieve a high level of animation adjustment, you must have rich experience Animators, and it takes a lot of time for animators to produce very good animation effects, which eventually led to the emergence of hardware facial capture systems. The traditional facial capture system, whether it is a sticker or a mask, has certain limitations. The facial sticker needs to be r...

Due to the more and more frequent application of 3D special effects and film and television animation, animation production requires a lot of time. The traditional animation production method is manual adjustment by animators. To achieve a high level of animation adjustment, you must have rich experience animators, and it takes a lot of time for animators to produce very good animation effects, which eventually led to the emergence of hardware facial capture systems

The traditional facial capture system, whether it is a sticker or a mask, has certain limitations. The facial sticker needs to be re-posted on the actor's face before each shot, and the incoherence of the nuances caused by the point difference cannot be avoided. Sexuality, and it consumes a lot of time and energy; using a mask can eliminate artificial uncertainty by determining points on the mask, but the price is surprisingly expensive, which increases the cost of special effects production
