Passive micro-optics sensors for 3D imaging

摘要

We use an array of microlenses to create multiple perspectives of a 3D scene (integral image). These perspectives are captured by a camera and digitally processed to extract the distance information from the differences of parallax. We present a technique to estimate the distance of objects and to digitally reconstruct the 3D scene in a computer. We show how this digital reconstruction can be used to visualize or recognize objects in a 3D scene.
