Depth cameras become increasingly popular in recent years. Ranging from interactive 3D game to photorealistic scene modeling, depth cameras present the great potentials toward many applications thanks to the advancement in sensing technology and the afforable price. Although depth cameras are actively adopted onto various research problems in computer graphics, many researchers are employing depth sensors without in depth understanding of their characteristics. In this tutorial, we introduce various depth cameras with their basic principle of depth sensing mechanism and analyze its performance and characteristics. Then, we will address the challenges in the use of depth cameras and practical issues for computer graphics applications. More importantly, we will discuss the potentials and limitations of depth cameras in the applications of computer graphics. This tutorial will be organized as follows; principle of various depth cameras, graphics applications with depth cameras, research issues (challenges/limitations) in the use of depth cameras and corresponding the state-of-art algorithms, potentials for new applications.
This tutorial will be a good starting point for new researchers in the field of computer graphics who are considering depth image for their work.
The audience is expected to take a basic computer graphics course offered in college.
