During the SIGGRAPH 2011 conference this week, researchers have demonstrated how a Microsoft Kinect motion controller device can be used to map and create 3D models of environments. The project is called KinectFusion, and using a Kinect device, the research team can quickly and easily render a 3D model of an entire room in real-time.

How KinectFusion Works
KinectFusion leverages the depth-sensing capabilities of the Kinect device to capture detailed 3D information about the environment. As the Kinect sensor is moved around a room, it continuously scans the surroundings, capturing depth data from different angles. This data is then processed in real-time to create a comprehensive 3D model of the space.
The technology works by fusing multiple depth images into a single, coherent 3D representation. As the space is explored, new views of the scene and objects are revealed, and these are fused into a single 3D model. The system continually tracks the 6DOF (six degrees of freedom) pose of the camera, which includes its position and orientation in space. As the camera moves through the scene, new depth data can be added or removed from this volumetric representation, continually refining the 3D model acquired.
Potential Applications of KinectFusion
The potential applications for KinectFusion technology are vast and varied. In the realm of gaming, for instance, this technology could revolutionize the way players interact with virtual environments. Imagine a game where the player’s physical room is seamlessly integrated into the game world, allowing for an unprecedented level of immersion. Virtual objects could be placed within the real-world environment, and players could interact with them as if they were physically present.
In architecture and interior design, KinectFusion could be used to create accurate 3D models of existing spaces, which can then be manipulated and modified in virtual reality. This would allow architects and designers to experiment with different layouts and designs without the need for physical alterations. For example, a designer could virtually “paint” walls, rearrange furniture, or even test different lighting conditions to see how they affect the space.
Moreover, KinectFusion has potential applications in fields such as robotics, where accurate 3D mapping of environments is crucial for navigation and interaction. Robots equipped with KinectFusion technology could navigate complex environments more effectively, avoiding obstacles and performing tasks with greater precision.
In the medical field, KinectFusion could be used for creating detailed 3D models of anatomical structures, aiding in surgical planning and medical education. Surgeons could practice procedures on virtual models before performing them on actual patients, potentially reducing the risk of complications.

In summary, KinectFusion represents a significant advancement in 3D modeling technology, with a wide range of potential applications across various fields. By leveraging the capabilities of the Kinect sensor, researchers have developed a system that can create detailed and accurate 3D models in real-time, opening up new possibilities for gaming, architecture, robotics, medicine, and beyond.
