In embodiments of a camera-based input device, the input device includes an inertial measurement unit that collects motion data associated with velocity and acceleration of the input device in an environment, such as in three-dimensional (3D) space. The input device also includes at least two visual light cameras that capture images of the environment. A positioning application is implemented to receive the motion data from the inertial measurement unit, and receive the images of the environment from the at least two visual light cameras. The positioning application can then determine positions of the input device based on the motion data and the images correlated with a map of the environment, and track a motion of the input device in the environment based on the determined positions of the input device.
