Abstract
To realize low-cost 3D mouse system, a multi points 3D measurement system is proposed. The system has two video cameras and acquires 3D coordinates of three colored markers. As the system uses only common devices, it is applicable to various fields. The measurement error of the marker position was 10mm at 100mm in front of the cameras. The system acquired 3D coordinates of the markers 30 times per second. As an application, we implemented a 3D mouse system, in which an object in the virtual space is picked and moved.
