A multimedia control interface in teleoperation

The system described is used in teleoperated robotics to give the human operator a visual aid for the perception of the remote scene and for the robot command in case of indirect viewing via a video camera. The device consists of a camera which gives the operator an indirect view of the real world, sensors allowing the rebuilding of a virtual world. The superimposition of the real and virtual worlds is carried out onto a video display terminal. The system´s functions are as follows: building graphics aids for the perception; building a geometric model of the environment; collecting data from the robot site to animate the computer picture of the environment model; matching computer-generated and video images; controlling the robot via the video display terminal
