像Kinect和PMD这样的消费级飞行时间深度相机便宜、紧凑，并在短距离应用中生成视频速率深度图。在本文中，我们将节能核线成像应用于ToF领域，以显着扩展这些传感器的多功能性：我们在户外明亮的阳光下展示了超过15 m范围的实时3D成像;对镜面和漫反射等全局传输效应的鲁棒性-这是ToF技术的第一次现场演示;在存在多个ToF传感器的情况下实现无干扰的3D成像，即使它们都以相同的光波长和调制频率工作;以及在存在严重相机抖动的情况下实现无模糊、无失真的3D视频。我们相信这些成就可以使如此廉价的ToF设备广泛应用于消费者和机器人领域。
Consumer time-of-flight depth cameras like Kinect and PMD are cheap, compact and produce video-rate depth maps in short-range applications. In this paper we apply energy-efficient epipolar imaging to the ToF domain to significantly expand the versatility of these sensors: we demonstrate live 3D imaging at over 15 m range outdoors in bright sunlight; robustness to global transport effects such as specular and diffuse inter-reflections---the first live demonstration for this ToF technology; interference-free 3D imaging in the presence of many ToF sensors, even when they are all operating at the same optical wavelength and modulation frequency; and blur-free, distortion-free 3D video in the presence of severe camera shake. We believe these achievements can make such cheap ToF devices broadly applicable in consumer and robotics domains.
