Mars Tech Images Inauguration
Feb 2009
WASHINGTON, Feb. 4, 2009 -- Using the same NASA technology that Mars rovers routinely use to image the Red Planet, photographer David Bergman created an unprecedented 1474-megapixel panoramic photo of President Barack Obama's inauguration that can be explored online.

"Covering the inauguration of President Obama was one of the biggest thrills of my life," said Bergman. "Little did I know that it would be topped by the reaction to a photo I made that day. …with the ability to zoom in and move around the photo, it turned into an international game of 'Where's Waldo?' In the first five days, the image was viewed by millions of people in 186 countries."


The interactive panorama of President Barack Obama's inauguration, created by photographer David Bergman and available on the Gigapan Web site. The ultrahigh resolution photo stitches together 220 individual shots using NASA technology created for the Mars rovers.
He created the image using Gigapan™, a camera system based on NASA technology. Visitors to the Gigapan Web site can pan around the rotunda and zoom in on some of the two million people. Because of its megahigh 1474-MP resolution (an ordinary digital photo contains less than 10 MP), you can see Hilary Clinton's white earrings, Barbara Bush's fuzzy black earmuffs, the word "Obama" stitched on spectators' winter hats, Yo-Yo Ma taking a picture with his iPhone, and much more.

A few years ago, NASA's Jet Propulsion Laboratory and Cornell University designed a special high-resolution camera called "Pancam" for the Mars rovers Spirit and Opportunity. Each of the twin rovers is equipped with a Pancam able to tilt 180° and rotate 360°, so the robotic geologists can snap photos in all directions. Special software stitches individual 1-MP digital images together into a high-resolution panorama and smooths out any anomalies.

Because the Pancams are mounted at eye level, viewing the final product helps scientists "look around" Mars as though actually hiking the desert-like terrain in their boots instead of via computer screens. The resolution of the images lets the scientists zoom in and scrutinize Martian rocks and other objects close up, just as they would if they themselves were kicking around in the dirt up there.

Gigapan was developed by Randy Sargent at NASA's Ames Research Center and Illah Nourbakhsh at Carnegie Mellon University. The panoramic photographs of Mars sparked an idea in their minds. It went something like this: "Let's learn to produce even bigger and better photos -- digital pictures composed of a billion or more pixels –- and bring that technology back to Earth." Sargent worked with Rich LeGrand of Charmed Labs LLC to design and produce the Gigapan products.

A Gigapan panorama is composed of many individual images taken one at a time and stitched together to form a whole. The inauguration photo contains 220 individual shots that required a total of 15 minutes to take.

"I'm really a traditional, still photographer," Bergman said. "I had seen the Gigapan system but never used it. Up until the day of the inauguration, I had no idea how to set it up. I fiddled around with it for a while in the hotel room to figure it out. That's a testament to how easy it is to use."

The biggest challenge, he said, was getting through security: "I had to be there at 6 in the morning and had to pass through three capitol police security checkpoints. I didn't have to face any Martian dust storms like the rovers do, but it was bitterly cold, and the ceremony didn't start until 11:30 a.m. I had no room for a tripod, so I had to clamp the Gigapan assembly to a rail and hope it worked."

Panoramas work best for landscape shots, where nothing is moving," notes Bergman. "So in that respect, the rovers have the advantage over me. At least I hope nothing is moving up there on Mars! Here on Earth, I was using Gigapan to photograph 2 million fidgeting people."

Indeed, there are a few amusing stitching errors: a pair of legs with no torso, some floating hats, a disembodied hand or two.

"But there were only about a dozen flaws," Bergman said. "That's amazing. A friend experienced with panoramic photography helped me easily correct those few errors to create the final print."

Although it is relatively new, Gigapan has already helped a lot of people in a number of ways. For example, it was used to create photographic overlays for Google Earth of areas affected by natural disasters, enabling relief workers to pinpoint areas in need of assistance in the aftermath of Hurricane Katrina, Hurricane Rita, and the 2005 earthquake in Kashmir. Botanists, geologists, archeologists, and other scientists around the world are using the technology to document diverse elements of the Earth's cultures and ecosystems.
