Development of microcontroller-based stereoscopic camera rig positioning system

A camera rig operator of stereoscopic camera system mostly adjusts a pair of camera manually when trying to make a 3D video that has good image depth. However, the process of this cameras positioning is cumbersome and time-consuming. In this paper, in order to solve those problems we develop a semiautomatic stereoscopic camera system; different from other works where a microcontroller, which considered low-cost and affordable, is employed to handle automation process of the system. Nevertheless, the camera rig operator is still required to carry out some manual processes such as inserting required parameters. In this system, the object distances approach is utilized; some object distance parameters, which obtained by a laser range finder, are entered into mathematical expressions in order to obtain correct positions of two cameras.. Based on experimental results, our proposed system enhances the process of the video capture process. In other words, it reduces the time required for every single scene capture process.
