Abstract: An increasing number of applications depend on accurate and fast 3D scene analysis, such as geometry reconstruction, collision prevention, mixed reality, and gesture recognition. The acquisition of a range map by image- based analysis or laser scan techniques is still time-consuming and expensive. Emerged as an alternative device to measure distance, depth camera enjoys some advances, e.g., lower price and higher photo speed, that have not be made in traditional 3D measuring systems. Recently, significant improvements have been made in order to achieve low-cost and compact depth camera devices that have the potential to revolutionize many fields of research, including computer vision, computer graphics and human computer interaction (HCI). These technologies are also starting to attract many researchers working for academic or commercial purposes. This paper gives an overview of recent developments in depth camera technology and discusses the current state of the integration of this technology into various related applications in computer vision and computer graphics.
