RIT becomes part of national plans to improve use of unmanned aircraft systems

Apr. 3, 2014

Ever since Amazon CEO Jeff Bezos suggested using drones to deliver packages 
to customers, discussions about the 
possible uses of unmanned aircraft 
have taken a new flight path. 

He might have easily been dismissed 
as a dreamer or an opportunist. But Bezos’ announcement prompted a shift in thinking about unmanned aircraft systems from flights-of-fancy to real possibilities such as crop surveying, fighting forest fires, pipeline inspections, rescue operations, wildlife monitoring and disaster response. As the ideas mature and unmanned aircraft 
systems become more sophisticated, 
standard processes to assess usage, 
safety and technology are necessary.

Drones, also referred to as unmanned 
aircraft systems and more commonly 
associated with the military and law 
enforcement, are being developed for 
a wider variety of commercial uses—
some of which may be developed at RIT. 

The university is part of NUAIR, the Northeast Unmanned Aircraft System Airspace Integration Research Alliance, a group of more than 40 companies and universities in New York and Massachusetts selected in December 2013 as one of six Federal Aviation Administration test sites in the U.S. The alliance will conduct research and testing of safe integration of unmanned aircraft systems in the national airspace system. Nineteen universities are involved with RIT and Massachusetts Institute of Technology as regional academic leaders, said Agamemnon Crassidis, associate professor of mechanical engineering in RIT’s Kate Gleason College of Engineering. 

“One of my key roles is to bring the 
universities together to see what kinds of research they are doing and how we can 
use that research,” said Crassidis, who will also serve on NUAIR’s board of directors. 

RIT is well positioned for this work with expertise in sensor and aeronautic system development from the engineering college, and in remote sensing and imaging from the Chester F. Carlson Center for Imaging Science. 

“This is a significant opportunity 
to expand use of remote sensing and 
imaging and make that imaging accessible to a broader constituency. In some disaster situations, especially with state or counties with tight budgets, access to low-cost 
imaging is big for them,” said Donald McKeown, distinguished researcher in 
the Carlson Center.

Unmanned aircraft have flown since 
the mid-1900s and are more than remote-
controlled model planes. Today, they consist of complex systems for collision avoidance, automated controls and navigation; they also integrate imaging systems to gather and process data. RIT researchers have 
already been developing aspects of these technologies and can contribute to 
improving unmanned aircraft systems. 

Regulations currently do not permit 
UAS operations above 400 feet without 
certification, and these allowances are 
given primarily to law enforcement or 
the military. The FAA has directed new 
test site teams like NUAIR to contribute recommendations about how corporate 
and commercial unmanned aircraft 
can be part of already crowded skies. 
The Northeast corridor where NUAIR 
will operate has some of the highest 
volumes of air traffic to control. 

The team has already received testing and development requests since the December announcement and expects to have a formal test facility and process up within six months. “It’s not a competition between the sites, it’s just a goal for us,” said Crassidis. “What RIT brings to the table is its strong industry partners and our hands-on 
approach to teaching. Students will be 
involved in multidisciplinary projects 
related to this, plus undergraduate and graduate research. We will make use of 
our facilities, particularly the machine shop, wind tunnel and the Aero Design Club.” 

Tim Southerton and Robert Jones, both fifth-year mechanical engineering students, are working on control systems for a Parrot AR Drone 2.0, a quadro-copter. They are upgrading the unmanned aircraft as part of a senior design project, integrating remote sensing equipment onto the frame and 
adding GPS navigation capabilities. 

These capabilities and others being developed make Bezos’ idea of delivering packages seem not so far-fetched. According to the Association for Unmanned Vehicle Systems International, UAS may provide 100,000 new jobs in the U.S. and more than $82 billion in economic outcomes by 2025. 

Talk about soaring to new heights.

David Messinger, director of the Digital Imaging and Remote Sensing Laboratory in the Chester F. Carlson Center for Imaging Science, tells NASA astronaut Donald Pettit, third from left, about the center?s work for the World Bank after the 2010 earthquake in Haiti. Stefi Baum, center director, left, and Robert Constantine, director of planned giving, right, listen on.

NASA astronaut Donald Pettit visited RIT's Chester F. Carlson Center for Imaging Science on Thursday, Jan. 9, while in town to give a lecture at the George Eastman House on his space photography.

Peter Blacksberg, a 1975 alumnus from the School of Photography, introduced Pettit to key members of the center: Stefi Baum, director; Joe Pow, associate director; and David Messinger, director of the Digital Imaging and Remote Sensing Laboratory.

"Knowing that taking photos from space posed some unique problems, Peter suggested that Don connect with our researchers here, thinking we might be able to help address some of these challenges," Pow said.

Pettit asked specific questions about imaging the sun from the space station.

"He posed for us an interesting question on what useful filtered photography of the sun might he do," said Baum. "We are investigating that and will be getting back to him soon."

Pettit has logged more than 370 days on the International Space Station and more than 13 spacewalking hours during his three times in space.

NASA astronaut presents Astronauts’ Guide to Photography in Space on April 13

Veteran of three space flights will share photographic awe, challenges and solutions he’s encountered from the International Space Station

Note: Video available for this story

NASA astronaut Donald Pettit has spent 370 days in space, orbiting the Earth more than 3,000 times while traveling 82 million miles. The space traveler has also taken nearly a half-million photos to capture the awe of his journeys.

“Looking at Earth from space is amazingly beautiful,” said Pettit. “It’s a perspective where you can see things on a length scale of half a continent.”

Pettit will present his lecture “Astronauts’ Guide to Photography in Space” at 6 p.m. Monday, April 13, in RIT’s Webb Auditorium. The event is free and open to the public.

Pettit’s innovative photographic work and passion for low light photography has changed the way we see Earth from space. He is a veteran of three space flights. He has lived aboard the International Space Station for 5 1/2 months during Expedition 6, was a member of the STS-126 crew, and again lived aboard the station for 6 1/2 months as part of the Expedition 30/31 crew. He has also logged 13 hours in space walks.

Millions of photos are used as part of the scientific data set for NASA. Pettit will share the photographic challenges faced by astronauts on board the International Space Station as well as some of the ingenious solutions he developed during his time in space.

“Frontiers are interesting places. They offer experience outside of the norm where the answers are not found in the back of the book. You have to figure things out for yourself,” said Pettit, whose fascination with photography began in middle school.

“Space is such a frontier and documenting that experience with photography presents not only a fascinating arena but challenges to the Earth-centric mind. Do you compose and shoot using Earth-standard expectations, thus making photographs pleasing to planetary dwellers? Or do you compose showing how life really is conducted there? Such is the photographer’s dilemma.”

Pettit will remain on campus April 14 and visit with students, faculty and staff in the College of Science, the Chester F. Carlson Center for Imaging Science and the College of Imaging Arts and Sciences. Part of the visit includes meeting with student researchers who will examine ways to reduce damage to photos caused by cosmic rays in space.

RIT alumnus Peter A. Blacksberg ’75 (photography) was instrumental in arranging Pettit’s visit.

RIT emerges as leader in drone research
Remote Sensing

Mar. 22, 2015
Sean Lahman


On a cold March afternoon, RJ Garma is flying a small quad copter in a parking lot at the Rochester Institute of Technology. The craft, about 2 feet wide, hovers several hundred feet in the air as Garma controls its movements using an application on his tablet. A camera mounted to the bottom of the copter sends overhead images of the campus back to him.

But Garma is not just a student out for a few hours of fun. He's a U.S. Air Force captain, a doctoral candidate in the school's imaging science program, and one of a handful of RIT students and faculty piloting a revolution.

The school has long been known for its expertise in aerial and satellite photography — a science known as remote sensing. So it's no surprise that RIT has now emerged as one of the world's leading centers for research on drones, small unmanned aircraft.

David Messinger, interim director of the school's Center for Imaging Science, says he gets calls almost every week from companies seeking this expertise, and graduating students are in extraordinarily high demand. Messinger says he can't recall one in the last 10 years who walked across the stage without having a job lined up.

"Our students don't bother going to the job fair," he says, "because when employers want our students they come here and talk to them directly."

The Digital Imaging and Remote Sensing Lab is the biggest group within the center, and about three-quarters of the DIRS students are working on masters and doctorate programs. They're highly sought after by government and industry alike.

The Federal Aviation Administration has also turned to RIT. With drone technology advancing faster than regulators can keep up, the FAA has designated six organizations across the country to conduct research to help devise rules for the operation of unmanned aircraft systems (UAS) in the United States. RIT and the Massachusetts Institute of Technology are the lead institutions for one of those six, a coalition of universities and industry called the Northeast UAS Airspace Integration Research Alliance, or NUAIR.

The development of inexpensive flying platforms — as well as ever smaller and cheaper digital cameras — has suddenly made aerial photography something anyone can do. For a few hundred dollars, you can walk into the mall or go online at Amazon and get a simple drone capable of taking pictures. With a modicum of skill, just about anyone can take overhead pictures of an urban landscape or a natural wonder.

Those breathtaking photos are nice, but what's really driving interest, what's turning this into a science and big business, is the idea of converting those aerial images into useful data.

"If I launched a drone and over the course of half an hour it covered the entire RIT campus at a 1-inch resolution, I'm not going to be able to physically look at all of that data." Messinger explained. "You've got to have some back end processing schemes that try to extract information out of the data.

"That's what you really want. You don't want the pictures. Nobody cares about the pictures. You want the information that you can get out of it," he said.

One of the first areas to leverage this new technology is precision agriculture, and researchers at RIT have been developing systems to address issues like drought management and disease detection.

Here's how it works. A farmer launches a small drone by simply throwing it into the air. The aircraft circles a couple of times to orient itself, then it goes back and forth until it has taken high-resolution pictures of each individual plant in his entire field. When it lands, the information is downloaded to a computer that can begin analyzing the images, asking questions about what the images show.

Questions like: Is that plant healthy? Is there a gap in my irrigation system? Is there a broken pipe someplace or an infestation of something that's moving across the field?

A test program launched in Genesee County last year, testing sensors that can estimate crop yields, spot potential pests or diseases, and help farmers to apply fertilizer more precisely. Another project by an RIT student examined vineyards in the Finger Lakes, using spectral imaging to assess water levels in plants.

Messinger says that the process usually starts with researchers going to customers and saying "this is what we can do, tell us if it's useful." If you could look at each plant in a thousand-acre field every day, what could you learn from that?

Sometimes it is about building these complex applications, but other times it's about developing solutions for simpler problems. Garma has been working on a system that takes off and follows him as he walks around. It flies in circles around him taking pictures. It's essentially a selfie drone, and it's not hard to imagine all sorts of practical applications for this technology.

Carl Salvaggio, an RIT professor who oversees the undergraduate program at the Center for Imaging Science, is working on building functionality into unmanned systems that makes them easier for nonexperts to use. You're not always going to have Ph.D.-level engineers like him to operate these systems, after all.

Salvaggio developed an inexpensive imaging system that can transmit live images of an area about an acre in size. It's designed for law enforcement or first responders who want to get an overhead view of what's going on in real time.

"A user can simply point at a spot on Google Maps," Salvaggio said. "The system will figure out where it is, turn and keep the camera trained toward that point on the ground the user selected."

In addition to the technology push, there's also an application pull: folks who come to RIT with a specific problem they need help solving. And perhaps the biggest problem is the one faced by the Federal Aviation Administration, which is charged with developing a plan for getting drones integrated into the national airspace.

They're concerned about these inexpensive fliers getting in the way of commercial aircraft, of course, and there are all sorts of technical and logistical issues that need to be addressed.

As one of the lead test centers for NUAIR, researchers at RIT are working on solutions for these challenges.

"With manned aircraft, we're pretty good at navigating from point to point," said Agamemnon Crassidis, a professor in RIT's Kate Gleason College of Engineering and the academic director for NUAIR.

Commercial aircraft use sophisticated navigation systems with an array of high-tech sensors.

"Those systems are large and they're expensive. You're not going to put an $80,000 inertial navigation system on a small unmanned aircraft," Crassidis said. "We're trying to develop sensors that are just as accurate but much cheaper, weigh less, use less power, and obviously are a lot smaller."

Collision avoidance is a major concern because drones are flying at lower altitudes than traditional manned aircraft. Crassidis says it's pretty easy to avoid buildings or hillsides, but that smaller obstacles — electrical wires or tree branches — present a more complex challenge. Part of the solution is developing better "detect and avoid" algorithms, but the real advances will be driven by those new sensors.

"The variety of potential applications for these unmanned systems is amazing, but we have to be able to do the testing to figure out how we can do those things safely," Crassidis said. "In terms of the technology, we're pretty close."

High-Resolution 3-D Scans Built from Drone Photos
Remote Sensing

A drone spent hours swarming around Rio’s iconic Christ statue to show a cheap way to capture highly accurate 3-D scans.

Mar. 19, 2015

drone flies around hand in Rio’s Christ the Redeemer stature to capture photos

The 30-meter tall statue of Christ overlooking Rio de Janeiro from a nearby mountain was under construction for nine years before its opening in 1931. It took just hours to build the first detailed 3-D scan of the monument late last year, using more than 2,000 photos captured by a small drone that buzzed all around it with an ordinary digital camera. The statue’s digital double was unveiled last month, and is accurate to between two and five centimeters, enough to capture individual mosaic tiles.

The project was intended to help efforts to preserve the statue and to demonstrate how drones could lead to a dramatic increase in high-resolution 3-D replicas of buildings, terrain, and other objects. Being able to easily and frequently capture detailed 3-D imagery could have many uses, such as speeding up construction projects and helping Hollywood make better special effects, says Christoph Strecha, CEO and cofounder of Pix4D, the Swiss company that led the project. It collaborated with drone manufacturer Aeryon Labs and researchers at PUC University of Rio de Janeiro.

Mapping tools from companies including Google and Apple have made outdoor 3-D imagery commonplace in recent years. But they are mostly built with 3-D data from aircraft carrying expensive equipment. The 3-D shape of buildings and terrain is most often captured using a technique called lidar, which uses lasers. The photo-real 3-D models of cities in Apple’s “flyover” mode are made by processing images captured by a complex and expensive array of cameras (see “Ultrasharp 3-D Maps”). Both techniques rely on very accurate GPS technology.

Software screen shot shows stitches of a high-resolution 3-D model

Software stitches a high-resolution 3-D model by processing overlapping photos.

Drones don’t have very reliable GPS fixes by comparison, and can’t carry large sensors or cameras. But they are cheap, and Pix4D’s software can build highly accurate models by comparing many different overlapping photos, says Strecha. In fact, using lidar would have been impossible with the Rio statue, Strecha says, because of its size, shape, and location.

Other projects have also been weaving 3-D models from drone photos. Researchers led by Horst Bischof, a professor at the Technical University of Graz, Austria, are developing software that extracts information from such images. For example, for a company that restores old buildings, the researchers made a version of the software that calculates measurements necessary for producing custom-fit thermal insulation.


With the image processing more or less a solved problem, the ambitions of drone scanning will depend more on how well drones can be controlled or coӧrdinated in challenging conditions like the winds around Rio’s Christ, or to cover larger areas, says Carl Salvaggio, a professor at Rochester Institute of Technology’s Center for Imaging Science. “Drones are good for small-scale projects but traditional aircraft offer the time in the air to collect whole cities,” he says. “Perhaps when there are ‘armies’ of drones in the air, we will see a different landscape emerge.”
