Kinect Range Sensing: Structured-Light versus Time-of-Flight Kinect
It helps scientists choose the appropriate Kinect device for their application by offering a detailed comparison, though it is incremental as it builds on existing devices without introducing new methods.
This paper compares the Kinect One (Time-of-Flight) and the first Kinect (structured-light) range sensing devices by proposing a framework of seven experimental setups to evaluate their characteristics, providing insights into the pros and cons of each for specific applications.
Recently, the new Kinect One has been issued by Microsoft, providing the next generation of real-time range sensing devices based on the Time-of-Flight (ToF) principle. As the first Kinect version was using a structured light approach, one would expect various differences in the characteristics of the range data delivered by both devices. This paper presents a detailed and in-depth comparison between both devices. In order to conduct the comparison, we propose a framework of seven different experimental setups, which is a generic basis for evaluating range cameras such as Kinect. The experiments have been designed with the goal to capture individual effects of the Kinect devices as isolatedly as possible and in a way, that they can also be adopted, in order to apply them to any other range sensing device. The overall goal of this paper is to provide a solid insight into the pros and cons of either device. Thus, scientists that are interested in using Kinect range sensing cameras in their specific application scenario can directly assess the expected, specific benefits and potential problem of either device.
