High-dynamic-range Imaging for Depth Maps

In this paper, I propose a method which applies the fundamental idea and technique of high-dynamic-range (HDR) imaging [5] to depth maps obtained from time-of-flight depth sensors. HDR imaging creates a single high-quality output from a number of photographs in different settings as its input. Similarly, my technique uses a set of depth maps, which are obtained from different settings (i.e. frequency of the time-of-flight camera [8]), to create a single highquality depth map. From the fact that differently ranged depth maps have different sweet spots, this method results in having a depth map that is both detailed in short distances and robust in long distances.
