Valve explains a little more about the technology behind their HTC Vive room scale tracking which is available now as open source.
Whether you’re building a VR golf club or an indoor quad-copter, 3D tracking is the heart of your product. Developed in-house at Valve, SteamVR Tracking is a hardware/software solution that lets your devices know in real time where they are, within a room. Valve is now making SteamVR Tracking fully available to other companies, without licensing fees.
The SteamVR Tracking Basestations sweep the room with multiple sync pulses and laser lines, reaching out to about 5 meters. By keeping careful track of the timings between pulses and sweeps, the SteamVR Tracking system uses simple trigonometry to find the location of each sensor to within a fraction of a millimeter. By combining multiple sensors, 2 basestations, as well as adding a high speed IMU (inertial measurement unit), SteamVR also calculates the tracked object’s orientation, velocity, and angular velocity, all at an update rate of 1000Hz.
