本文描述了一种利用核线平面图像(EPI)分析从全相机图像中获取3D信息的有效方法。使用两种类型的全息相机来生成时空体积，该时空体积是堆叠在时空空间中的一系列全像图像。对于全像的EPI分析，我们在这样的时空体积中检查了不同类型的横截面。为了真实地进行EPI分析，我们必须找出现实世界中垂直直线被保留为直线的横截面。我们将这样的横截面定义为全EPI。为了利用全方位EPI的特点获取三维信息，我们提出了基于模型的EPI分析。为了验证该方法的有效性，我们使用室外环境的全方位视频展示了实验结果。
The paper describes an efficient method to obtain 3D information from omni-camera images using epipolar-plane image (EPI) analysis. Two types of omni cameras are employed to make a spatio-temporal volume, which is a sequence of omni images stacked in the spatio-temporal space. For the EPI analysis of omni image, we examine different types of cross sections in such spatio-temporal volumes. To conduct the EPI analysis realisticly, we must find out the cross section on which the vertical straight lines in the real world are preserved as straight lines. We define such a cross section as omni EPI. To acquire 3D information using the characteristics of the omni EPI, we propose model based EPI analysis. To demonstrate the effectiveness of this method, we present experimental results using an omni video of outdoor environments.
