Abstract

Two cameras and stereoscopic camera rig are required to capture the stereoscopic image. Interaxial distance and alignment are two of the most important factors in the shooting of stereoscopic image. However, it is time consuming and low accuracy to control the Interaxial distance and alignment by using manual 3D camera rig. This is because when the Interaxial distance and alignment of the image are not controlled accurately, a complicated and longer handling time are required for editing operation. This results in a low quality final 3d image. To overcome these defects, automatic camera rig has been developed but the current automatic camera rig only focus on the simple movement. Hence, In this paper, a automatic stereoscopic camera rig system based on PLC(Programable Logic Controller) control has been designed to create a Stereoscopic image according to shooting environment. Automatic System of Stereoscopic Camera Rig consists of horizontal 3D camera rig and a Control Box. Horizontal 3D camera rig is designed using hardware components like ‘Long Stage’, ‘Goniometer Stage’ and ‘Rotation Stage’ while Control Box is designed using PLC, Motor Driver and Touch Panel to control the designed horizontal 3D camera rig automatically. Various experiments are performed in order to demonstrate the effectiveness of stereoscopic 3D shooting using the designed automatic stereoscopic camera rig system. The stereoscopic image can be captured by any public user with the designed automatic stereoscopic camera rig system in an efficient way without any severe visual problem.
