A Mobile System for Multi-video Recording

We present a portable system to record synchronised, multi-video data for vision applications such as 3D reconstruction and video-based rendering of dynamic scenes. The aim of the project is to gain access to a greater number of scenes than what a static, wired indoor studio allows for. The portable acquisition system is constructed from a number of independent modules, each consisting of a FireWire camera and a laptop. Our software utilises wireless networking making the system behave like a tightly coupled unit without requiring the modules to be physically connected to each other. The scheme also includes an external calibration method suitable for general scenes. The system is scalable and allows for easy transportation and adhoc setup and configuration. We present recent results acquired in the field and their use for free-viewpoint video.
