# LiveScan3D # LiveScan3D is a system designed for real time 3D reconstruction using multiple Kinect v2 depth sensors simultaneously at real time speed. The produced 3D reconstruction is in the form of a coloured point cloud, with points from all of the Kinects placed in the same coordinate system. Possible use scenarios of the system include: * capturing an object’s 3D structure from multiple viewpoints simultaneously, * capturing a “panoramic” 3D structure of a scene (extending the field of view of one sensor by using many), * increasing the density of a point cloud captured by a single sensor, by having multiple sensors capture the same scene. You will also find a short presentation of LiveScan3D in the video below (click to go to YouTube): [![IMAGE ALT TEXT HERE](http://img.youtube.com/vi/9y_WglwpJtE/0.jpg)](http://www.youtube.com/watch?v=9y_WglwpJtE) At the moment connecting multiple Kinect v2 devices to a single computer is difficult and only possible under Linux. Also, the number of the devices or capture speed might be low, because of the limitations of the PCI-E bus. Because of those limitations, in our system each Kinect v2 sensor is connected to a separate computer. Each of those computers is connected to a server which governs all of the sensors. The server allows the user to perform calibration, filtering, synchronized frame capture, and to visualize the acquired point cloud live. ## How to use it ## To start working with our software you will need a Windows machine with the Kinect for Windows SDK 2.0, and at least a single Kinect v2 device. You can either build LiveScan3D from source which is easiest using Visual Studio, or you can download the binaries from: http://home.elka.pw.edu.pl/~mkowals6/. Both the binary and source distributions contain a manual (in the docs directory) which contains the steps necessary to start working with our software (it won't take more than a couple of minutes to set up). ## Where to get help ## If you have any problems feel free to contact us: Marek Kowalski , Jacek Naruniec .
