我们介绍了编码双桶（C2B）成像，这是一种新的计算传感器工作原理，应用于主动三维形状估计和编码曝光成像。C2B传感器通过控制像素的两个“桶”中的哪一个应该整合它来调制到达每个像素的光。C2B传感器每视频帧输出两幅图像-每个桶一个-并允许快速，完全可编程，按像素控制活动桶。以这些属性为出发点，我们(1)开发了这些传感器的图像形成模型，(2)将它们与可编程光源耦合以获取照明马赛克，即在许多不同照明条件下的场景图像，其像素已在一次拍摄中复用并获取，以及(3)展示如何处理照明马赛克以获取传感器原生分辨率的动态场景的实时视差或法线图。我们展示了这些功能的第一个实验演示，使用功能齐全的C2B相机原型。这个独特原型的关键是一个新颖的可编程CMOS传感器，我们从头开始设计，制造并变成一个工作系统。
We introduce coded two-bucket (C2B) imaging, a new operating principle for computational sensors with applications in active 3D shape estimation and coded-exposure imaging. A C2B sensor modulates the light arriving at each pixel by controlling which of the pixel’s two “buckets” should integrate it. C2B sensors output two images per video frame—one per bucket—and allow rapid, fully-programmable, per-pixel control of the active bucket. Using these properties as a starting point, we (1) develop an image formation model for these sensors, (2) couple them with programmable light sources to acquire illumination mosaics, i.e., images of a scene under many different illumination conditions whose pixels have been multiplexed and acquired in one shot, and (3) show how to process illumination mosaics to acquire live disparity or normal maps of dynamic scenes at the sensor’s native resolution. We present the first experimental demonstration of these capabilities, using a fully-functional C2B camera prototype. Key to this unique prototype is a novel programmable CMOS sensor that we designed from the ground up, fabricated and turned into a working system.
