Abstract: The invention discloses a method for real-time face animation based on single video camera. The method tracks 3D locations of face feature points in real time by adopting a single video camera, and parameterizes head poses and facial expressions according to the 3D locations, finally may map these parameters into an avatar to drive face animation of an animation character. The present invention may achieve a real time speed by merely adopting a usual video camera of the user instead of an advanced acquisition equipment; the present invention may process all kinds of wide-angle rotations, translation and exaggerated expressions of faces accurately; the present invention may also work under different illumination and background environments, which include indoor and sunny outdoor.
Abstract translation: 本发明公开了一种基于单摄像头实时面部动画的方法。 该方法通过采用单个摄像机实时跟踪面部特征点的3D位置，并根据3D位置对头部姿势和面部表情进行参数化，最后将这些参数映射到头像中以驱动动画角色的面部动画。 本发明可以通过仅使用用户的普通摄像机而不是先进的采集设备来实现实时速度; 本发明可以精确地处理各种广角旋转，平移和夸张的表情; 本发明也可以在不同的照明和背景环境下工作，包括室内和阳光充足的室外。

Abstract: A multi-node data synchronous acquisition system and a method for real-time monitoring of underwater surface deformation. The system includes at least four sensor arrays, where each of the sensor array consists of a plurality of ribbon-like rigid substrates connected by movable joints. On each section of rigid substrate, three sensor units are respectively connected to a slave station data acquisition unit through cables. The slave station data acquisition unit is connected with a central controller through a cable. The central controller includes a compressive cabin outside and an embedded controller and a power supply inside. Each slave station data acquisition unit acquires data from an MEMS attitude sensor and then transmits it to the embedded controller. The present invention may realize synchronous acquisition of underwater or even underwater multi-node data, implement three-dimensional surface reconstruction, and may be used for improving the ocean observation capability.
