How to capture free viewpoint video?
To capture free viewpoint video, there are several methods and techniques available. One approach is to use a multi-camera array consisting of mobile phones with time synchronization, which allows for easy capture and processing of volumetric content . Another method involves using a network of cameras to simultaneously capture images of the scene, and then generating a virtual view by adjusting pixels of the captured images based on a three-dimensional model of the scene . Additionally, a sampling density can be determined to capture a plurality of two-dimensional images of a three-dimensional scene, which can then be used to generate novel viewpoints in a light field reconstruction framework . Another technique involves obtaining a multi-viewpoint video and generating a free-viewpoint video of a virtual viewpoint based on the multi-viewpoint video, using a three-dimensional model to calculate components of pixels for the target areas . Finally, for setting up a free-viewpoint capturing system, spatial alignment of the sensors can be achieved using an easy to assemble structure and exploiting the a-priori knowledge of the structure's geometry .
