The output is synchronized without stuttering, ghosting, or misalignment, directly providing a virtual camera stream that seamlessly integrates with various live streaming and video call software. It is a hardcore real-time face processing tool aimed at content creation, live streaming operations, and creative interaction.
WHY IT MATTERS
数字分身的门槛，不是能换脸，而是能稳定直播。The threshold for a digital avatar is not being able to swap faces, but being able to stream stably.
QR Qi孪生围绕长时间实时输出设计，从采集、关键点追踪、纹理迁移到虚拟摄像头形成低延迟链路。系统重点解决表情漂移、遮挡穿帮、光线突变和音画不同步等直播级问题。QR Qi Twin is designed around long-duration real-time output, forming a low-latency chain from acquisition, keypoint tracking, texture transfer to virtual cameras. The system focuses on addressing live-stream-level issues such as expression drift, occlusion breakthroughs, sudden light changes, and audio-video desynchronization.
01时序一致Real-Time Face Rendering
面部变化与原始动作保持同一时间轴，降低口型和表情错位。Facial changes remain on the same timeline as the original actions, reducing mismatches between mouth shapes and expressions.
02环境融合Adaptive Lighting
持续适配角度、肤色与光照变化，减少贴图式面具感。Continuously adapt to changes in angle, skin tone, and lighting to reduce the patch-like mask effect.
03直播输出Multi-Channel Output
通过标准虚拟摄像头进入推流和会议软件，不改变原工作流。Enter streaming and conferencing software through a standard virtual camera without changing the original workflow.

依托自研人脸渲染推理引擎，设备摄像头采集画面的同时瞬间完成人脸特征提取、面部纹理迁移、光影自适应融合，完整保留原有画面的肢体动作、环境光线、背景场景，表情跟随原生动作实时联动，眨眼、挑眉、嘴角微动作同步跟随，不存在普通工具常见的人脸漂移、面具感、画面撕裂等问题。区别于离线后期换脸，Qi孪生做到边采集边渲染，推流输出和原生摄像头时序完全对齐，真正满足直播这种强实时业务要求。Relying on a self-developed facial rendering inference engine, while the device camera captures footage, it instantly completes facial feature extraction, facial texture transfer, and adaptive light and shadow fusion, fully preserving the original body's movements, ambient lighting, and background scene. Expressions are synchronized with the native movements in real-time—blinking, eyebrow raises, and slight mouth movements follow simultaneously—without common issues found in ordinary tools such as facial drifting, mask-like appearance, or image tearing. Unlike offline post-production face swapping, Qi Twin performs capturing and rendering simultaneously, with streaming output fully synchronized with the native camera timing, truly meeting the strong real-time requirements of live broadcasting.
摄像头实时流直接做换脸运算，输出虚拟摄像头信号，可直接喂给直播伴侣、OBS以及各类视频通话软件，直播推流、线上视频连线全程同步，不会出现音画不同步、人脸滞后现象。支持单人脸实时置换，可一键切换目标人脸素材，快速切换出镜形象。The camera live stream directly performs face swapping operations and outputs a virtual camera signal, which can be directly fed to Live Companion, OBS, and various video calling software. Live streaming and online video calls are fully synchronized, without audio-video mismatch or face lag. It supports real-time replacement for a single face, allows one-click switching of target face material, and quickly changes the on-screen appearance.
