Virtual Environment (VE) techniques provide a powerful tool for the visualization of the 3D of a teleoperation work site, particularly when 'live' video display is inadequate for the task operation or its transmission is constrained, for example by limited bandwidth. However, the ability of VE to cope with the dynamic phenomena of typical teleoperation work sites is severely limited by its per-defined model- based nature. Thus, an on-line composing mechanism is needed to make it environment complaint. For this purpose, this paper describes an on-line technique for camera calibration and an interactive VE modeling method that works ona single 2D image. Experiments have shown that the methods are convenient and effective for on-line VE editing.
