Researchers Develop Technique To Reconstruct 3-D Motion

Carnegie Mellon researchers have developed techniques for combining the views of 480 video cameras mounted in a two-story geodesic dome to perform large-scale 3-D motion reconstruction, including volleyball games, the swirl of air currents and even a cascade of confetti.

Though the research was performed in a specialized, heavily instrumented video laboratory, Yaser Sheikh, an assistant research professor of robotics who led the research team, said the techniques might eventually be applied to large-scale reconstructions of sporting events or performances captured by hundreds of cameras wielded by spectators.

In contrast to most previous work, which typically has involved just 10 to 20 video feeds, the Carnegie Mellon researchers didn't have to worry about filling in gaps in data; their camera system can track 100,000 points at a time. Rather, they have to figure out how to choose which of the hundreds of video trajectories can see each of those points and select only those camera views for the reconstruction.

"At some point, extra camera views just become 'noise,'" said Hanbyul Joo, a Ph.D. student in the Robotics Institute. "To fully leverage hundreds of cameras, we need to figure out which cameras can see each target point at any given time."

Lower Hamerschlag Drive To Close for Scott Hall Steel Erection

The lower part of Hamerschlag Drive will be closed to all vehicular traffic from 6 a.m., Friday, July 25 through 6 p.m., Saturday, July 26 for the mobilization of a 300-ton, 300-foot-tall crane that will be used to erect the steel structure for Scott Hall.

There will be no access from Hamerschlag Drive to the Physical Plant Building, the Roberts Hall loading dock, the Gates High Bay and parking garage, and to the loading docks for Doherty and Wean halls. Permit holders in the Gates parking garage may use the East Campus Garage during this closure.

Carnegie Mellon Police along with Pittsburgh Police, paramedics and fire departments will have unrestricted access to lower Hamerschlag Drive through an emergency access temporary road from Frew Street through the Scott Hall construction site.
