TL;DR: In this paper, the authors present a cooperative work as if workers in remote places are happened to be present at that place by surrounding one work space by synthesizing a substantial object with a display object by video, which is transmitted from the other place, so as to display a shared space in workshops in respective remote places.

Abstract: PURPOSE:To execute cooperative work as if workers in remote places are happened to be present at that place by surrounding one work space by synthesizing a substantial object with a display object by video, which is transmitted from the other place, so as to display a shared space in workshops in respective remote places. CONSTITUTION:When the object is placed on the desk of a space A, a camera 1 for space video, and the video is displayed on the display part 8' of a space B through a communication interface 2. An image input part 3' extracts the work space and the characteristic form of the object for comparing scales. A display size comparison part 4' calculates a display scale factor and a display angle based on the initialization of the screen size of the display part 8'. A scale correction signal transmission part 5' executes feedback control so that an image pickup size and a display size are approximated through the communication interface 2. An image processing part 6' micro-adjusts a rotation and a scale conversion so as to synthesize the display object with the substantial object.
