Synchronized Reality^TM

Now my fellows and I are working on a protoype system of `the information media environment'. On the 1st step, we installed the SCRAPER system in 1998 which can reconstruct the 3D shape of the moving objects in voxel format with distributed workstations. We choose the 2nd lecture room at the 4th floor in the building of the department of Information Science, Kyoto university. The prototype system uses 8 pan/tilt cameras, produces the result about 7 snapshots per second (fps?) with 4 SUN Ultra2170s and 4 other SUN workstations.

These snapshots were taken in October 1998.

	A real image. There are 8 cameras and the images are captured at 320x240xRGB format and are sent to clients by 30fps (at most).
	A view from one camera. The pyramids show the viewing volumes of the other cameras in real-time.
	Visualized static object models which are given to the system in advance. The camera parameters are the same as the above picture.
	The static object models and the viewing volumes are overlapped on the real image. This is the basic view provided for users.
	A result (one snapshot) produced by the SCRAPER system. Voxels are displayed as white dots.
	Whole the information is synthesized on the same image plane. Blue color of the viewing volume indicates that its camera serves to the other users/agents. A human CG model is displayed based on the simple location estimation result.
	Another snapshot can be seen by VRML1.0. Please click the left image. You need VRML1.0 (or later) browser. To see the intended texture, you need cosmoplayer2.0 or later.

Active only when we run demo program... Thank you.

• Current camera resource
  You can see how the agents share the limited pan-tilt cameras.
• Current dynamic objects
  Report of our sketched world generation system.
• Objects in the lecture room
  Permanent information about objects that would be found in the real lecture room and `synchronized' lecture room (sketeched world).
