Marsden grant to study sophisticated cameras
When Dr Lee Streeter heard he’d won a Marsden grant to continue his time-of-flight photography research, he took a day’s
leave to celebrate.
“I kept going onto the Royal Society website, just to check my name was really there,” he says.
Dr Streeter, an electronic engineer and teaching fellow at the University of Waikato, has been awarded $300,000 Marsden
Fast Start grant over three years to work on improving motion factors in time-flight photography.
Fast Start grants are awarded to young and emergent researchers. Dr Streeter is one of a few people around the world to
be researching time-of-flight range imaging cameras and looking for ways to improve the data these cameras provide.
“These cameras are used in gaming, such as Xbox One, and more sophisticated cameras are used at industrial level,
important to show extra depth of information, telling us what things look like and where they are. They provide
important information about the shape of objects. We can see how big, how far away they are, and how flat or how round
the sides are,” Dr Streeter says.
Time of flight cameras have been designed to measure the distance within static scenes but can’t interpret scenes with
complicated motion. “So I’m going to try to re-engineer a new camera concept that will transform complex motion from a
source of error to an essential feature – trying to measure distance despite motion.”
Dr Streeter says time-of-flight imaging shares a lot of similarities with radar, but there are also big differences.
“I’ll be drawing on existing technologies and combine them with some ideas I’ve had. I’m well aware what I’m setting out
to do is a lofty goal but this grant gives me time think really deeply about this problem, to pull in ideas from other
fields and to come up with new ones.”
He says he’s fortunate to have a like-minded colleague in Dr Gordon Wetzstein at Stanford University in the United
States who’ll be his associate investigator on the project.
“But none of this would have happened without the support I’ve had from staff at Waikato –Professor Ilanko, Dr Adrian
Dorrington and others University of Waikato time-of-flight research group. Everything’s come together, being in the
right place at the right time. I can’t wait to get on with it.”
Two other University of Waikato emerging researchers, Dr Holly Thorpe and Dr Phil Ross, also received Fast Start grants
of $300,000. Dr Thorpe will examine young people’s engagement with informal sports to improve their own and others’
wellbeing in war-torn and post-disaster places. Her case studies will take in Afghanistan, Gaza, Christchurch and New
Orleans. Dr Ross will be combining archaeology and molecular ecology with Matauranga Māori (Māori knowledge) to gain a
better understanding of how early Māori manipulated their marine environment.
Computer Scientist Associate Professor Eibe Frank was awarded $410,000 to investigate alternative and more user-friendly
approaches to deep learning. The Marsden Fund is administered by the Royal Society of New Zealand and supports
excellence in leading-edge research.
