Zebedee is a handheld 3D mapping system, which consists of a lightweight laser scanner with 15–30m maximum range (dependent on surface reflectivity and environmental conditions) 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 laser'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 an IEEE Transactions on Robotics article. The technology is now commercially available as ZEB1 and its sister device ZEB REVO through our partner, GeoSLAM. Please contact firstname.lastname@example.org with any inquiries.
