Combining tiny cave camera, iris recognition technology for military, homeland security

scanner, Smart-Iris will make it possible for people to pass through a standard doorway, each one getting their iris scanned — without so much as even pausing — by equipment mounted on walls or door frames. At the same time, the camera would maintain high resolution and more than 150 pixels across the iris.

That could benefit DHS. More than 600 million people pass through security to fly aboard commercial airlines each year, according to the agency. DHS relies on the latest technology to monitor more than 700 security checkpoints and 7,000 baggage screening areas.

“Our goal is to develop an iris recognition system that is unobtrusive and accurate. We want to ensure that the right people have access, and that potential intruders are identified, all without impacting flow in high-traffic areas,” said Etter, who directs the Lyle School’s Caruth Institute for Engineering Education.

Into caves and dark alleys

To develop AIM-CAMS, Panoptes is being paired with new off-the-shelf pocket projector technology known as Pico. Pico projectors, often compared in size to a candy bar, make it possible to project digital pictures taken by cell phones and other portable devices onto any wall for large-format viewing.

Combining Pico with Panoptes will allow the low-resolution camera to be used in dark places, such as caves and urban alleys, providing troops with situational awareness, said Christensen.

Katie Drummond writes that the new technology will eliminate problems like glare, eyelashes, dim lighting — and an unwillingness to stop and stare directly into a dedicated iris-detection camera. Instead, Panoptes devices will zero in on a face, no matter angle or movement, then narrow right into the iris. A long line of people, moving through a line, could be scanned by wall-mounted cameras and they wouldn’t even notice it was happening.

A new algorithms are being developed by Etter and colleagues to identify individuals based on segments of their iris, rather than a full frontal scan. “Ideally, when you walk down a hallway, no matter where your head is looking, the device can grab your eyeball and detect what it needs to,” Christensen said. And where possible security and defense applications are concerned? “You can let your imagination fly with that one.”

With this latest development, Christensen also sees widespread civilian application, as part of “the cell phone of the future.” He’d like to see the camera-projection device incorporated into phones, and says they’d be able to photograph the page of a book “down to the smallest lettering,” or detect counterfeit cash by “picking up the texture of a $20 bill.”

SMU is collaborating on the research with Santa Clara University in California, Northrop Grumman, and Draper Laboratory. Funding came from the DARPA, Office of Naval Research, and Army Research Laboratory.
