Performance Capture of Actor from Active Multiple Cameras

本报告描述了带有多个摄像头的动作捕捉系统的两个新功能。首先，我们开发了一种从多个摄像机部分观察到的几个身体部位重建全身姿势的方法。其次，提出了一种将背景全景图像与平移相机图像进行匹配的摄像机标定方法。新的校准方法使我们能够在更大的空间范围内测量人类的行为。

This report describes two new functions of a motion capture system with multiple cameras. First, we develop a method to reconstruct a whole-body pose from a few body parts partially observed by multiple cameras. Second, we propose a camera calibration method which matches a panoramic image of the background with an image from panning camera. The new calibration method allows us to measure human action in a wider range of space.
