Zebedee is a handheld 3D mapping system, which consists of a lightweight LiDAR scanner with approximately 30m (100ft) maximum range and a industrial-grade MEMS inertial measurement unit (IMU) mounted on a simple spring mechanism. As an operator holding the device moves through the environment, the scanner loosely oscillates about the spring, thereby producing rotational motion that converts the LiDAR's inherent 2D scanning plane into a local 3D field of view. With the use of proprietary software, the six degree of freedom sensor trajectory can be accurately and continuously calculated from the laser and inertial measurements in real-time, and the range measurements can be projected into a common coordinate frame to generate a 3D point cloud. Zebedee has evolved from (and alongside) general research into 3D localization and mapping for autonomous robots. The main technical details are described in a recently published IEEE Transactions on Robotics article. The technology is now commercially available as ZEB1 through our partner, 3D Laser Mapping.

The Questacon – the National Science and Technology Centre, is located on the southern shore of Lake Burley Griffin in Canberra, Australia. It is a large centre with more than 200 interactive exhibits relating to science and technology. Here are the results of a scan conducted in September 2012 acquired during a 14min walk inside and around the centre. The data was downloaded and processed in less than 30min. Read More ...

The SPAR International 2012 Conference venue in Houston, Texas, is depicted in the Figure. Data collection occurred over three twenty-minute sessions during normal conference hours, with the operator walking though variously-sized rooms and hallways, going up and down stairways and escalators, and transitioning between indoor and outdoor environments. The high level of robustness developed into the system ensures that the presence of moving people and traffic in the busy conference environment does not adversely affect the solution. In the zoomed in detail, one can see the unique scanning pattern from the oscillatory spring motion that allows the operator to capture areas with minimal shadowing in the data. Read more ...
