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.
