Time-of-flight (ToF) cameras are fast becoming the method of choice for depth sensing in a wide range of applications. Several low cost and compact ToF systems are available as commodity devices, including the Microsoft Kinect and the Intel SoftKinectic sensors. In addition to depth recovery, ToF cameras are also being repurposed for recovering a variety of scene information, such as reflectance properties and intrascene light transport. This tutorial introduces our audience to recent advances made in the field of ToF imaging, including a discussion on the core challenges faced by ToF cameras and existing solutions, novel applications such as transient imaging, measuring depths around the corners and estimating fluorescence and material properties.
