Stereoscopic Vision at Large Distances

这个项目测量了立体视觉的好处，立体视觉是一种从双目视觉获得的深度感知，距离为几十到几百米。在这个范围内，我们的立体视觉能力几乎一无所知，因此这是关于人类视觉的新的基础数据。我们将研究如何单目和双目信息在远距离组合；一个与传感器融合有关的问题，是神经科学的中心问题。这项研究对任何涉及远距离判断的任务也至关重要，包括识别远距离目标及其关系，以及直升机等交通工具的视觉引导。它还将为双目仪器的设计者提供关键信息。

This project measures the benefits of stereopsis, which is a perception of depth obtained from binocular vision, at distances of tens to hundreds of meters. Almost nothing is known of our stereoscopic abilities over this range and thus this is new and fundamental data about human vision. We will investigate how monocular and binocular information is combined at large distances; an issue relevant to sensor fusion, a central problem in neuroscience. The research is also critical for any tasks involving judgments over long distances including the recognition of distant targets and their relationships as well as the visual guidance of vehicles such as helicopters. It will also provide critical information to designers of binocular instruments.
