Research And Implementation Of Augmented Reality System Based On Depth Camera

Augmented reality technology is extracted through the computer or IT, simulatefrom some kinds of virtual information, and then superimposed on the real-time andaccurate after the real environment and presents a new sensory experience mix of realand virtual information. Since inception in the1990s, much in scientific research,business, entertainment and other industries contributed greatly to the development andapplication of AR technology. However, since these systems are basically comprises afixed marker or a fixed texture virtual information and performance, is not flexibleenough and freedom, with the objective unconstrained environment photorealistic reachgood results, so that the application is AR certain restrictions; while basically based onmulti-camera vision system to achieve the effect can be achieved, but the theory andimplementation are too complicated. In this paper, Microsoft introduced a newgeneration of interactive device Kinect depth camera system, based on real-lifescenarios to develop a model based on the AR System:1) From the camera calibration principle, the introduction of the Kinect depthcamera geometric transformation mapping their internal transformation parametersmeasured. While the depth of the analysis Kinect Kinect on the basis of converting acolor video image and a depth image registration work. Finally, the Kinect depth imageof the original rough to do repair process.2) Addressed the use of Kinect scene depth data to extract geometric informationtechnology based on depth information of the dividing plane and the real objectsegmentation method.3) In Kinect SDK and XNA, based on a new set of building free registration actualsituation fusion AR system. Next, based on the former plus Kinect excellent interactivefeatures, improved interactive augmented reality system, which can be achieved basedreal scene and virtual objects superimposed freedom for simple interaction with thehuman body to achieve realistic integration.Features and advantages of this system are: relatively inexpensive equipmentcoupled with advanced Kinect depth-sensing system that can to a certain extent as the AR scene induction system and advanced bone Kinect-based detection technology, easyto implement deeper interoperable AR System.For AR technology implementation, the popularity of Kinect brings morepossibilities and prospects.
