Keeping the past in the future with 3-D mobile mapping

Apr 23, 2013

Australian researchers are using a novel mobile laser 3D mapping system called Zebedee to preserve some of the country's oldest and most culturally significant heritage sites.

The new joint research initiative between CSIRO and The University of Queensland aims to collect detailed 3D maps of historic sites of Moreton Bay. With the assistance of Queensland Parks and Wildlife Services, the research team have collected data from a number of heritage sites including the 19th century defences at Fort Lytton and Peel Island's leper colony buildings.

At the core of the technology, developed by CSIRO's Lab in Brisbane, is a that swings back and forth on a spring to capture millions of detailed measurements. Zebedee gives researchers the ability to reliably map an environment in 3D by simply walking through it.

"This technology is ideal for cultural heritage mapping, which is usually very time consuming and labour intensive. It can often take a whole research team a number of weeks or even months to map a site with the accuracy and detail of what we can produce in a few hours," said Dr Jonathan Roberts, Director of CSIRO's Autonomous Systems Lab.

"Zebedee has allowed us to capture a detailed record of several key cultural heritage sites ranging from those which are fragile and at risk of damage through natural disasters to those which are remote and difficult to get to," said Professor John Macarthur, Dean and Head of the School of Architecture at The University of Queensland.

"We're looking to use these maps in the future to create an archive of rich data about sites, which will allow us to analyse them without costly and time consuming hand measuring. From this, we have already analysed important aspects of Australian history. For example, the detailed map of Peel Island's many small buildings allowed us to analyse architecture used to racially segregate people within the leper colony. The point cloud data clearly depicts how cramped and crowded the living quarters for Indigenous people were, when compared to the non-Indigenous people who lived in their own huts with scenic verandas," he said.

The research will be officially launched by the Honourable Andrew Powell, Queensland's Minister for Environmental Protection and Heritage during an event to mark the beginning of Australia's National Heritage Week celebrations at Fort Lytton today.
