Computational Depth Sensing : Toward high-performance commodity depth cameras

In this article, we introduce this important concept and provide an overview of the latest representative techniques. By bringing together and analyzing interdisciplinary research from signal processing, computer vision, and optics communities, our goal is to shed light on the development of future commodity depth cameras, which is a potential great interest to a broad audience. Specifically, this article will focus mainly on the structured light approach, which provides a large degree of freedom for the design of depth cameras. A recent review of ToF cameras is given, and another on light-field cameras is given. Also, a comprehensive review on traditional structured light cameras can be found. This article will be complementary to these reviews.
