Flexible objects such as clothes are hard to be handled by robots. But the working conditions for laundry factories are severe because of dusts, heats and steams. To automate these factories, 3D vision systems are dispensable to recognize the 3D shape of flexible clothes. Here, 3D robot vision systems with stereo cameras and a pattern projector have been(More)
Flexible objects such as clothes are hard to be handled by robots. But the working conditions for laundry factories are severe because of dusts, heats and steams, and full automation systems which can handle clothes are highly required. To automate these factories, 3-D Vision systems and flexible handling mechanism are dispensable to handle flexible(More)
From the early stage of production lines, it aimed to accomplish the full automation of production. In 1980's, the goal of fully automated production lines had been accomplished through the introduction of micro-computers, robots, vision systems, etc. But the full automation had many problems such as the difficulty of the production changes, etc. Then, the(More)
The accuracy of Stereo 3D Measurement Method strongly depends on the accuracy of calibration. But, it's very difficult to maintain optical systems in exactly the same. So, we are always pressed by painful calibration. For this, some self-calibration methods are developed, but they are not a panacea for all situation. To solve this problem, we proposed(More)
