Sanborn Advances Indoor Mapping
Move over R2-D2! Designed exclusively for indoor mapping applications, the robotic Sanborn Platform for Indoor Mapping (SPIN) is a compact, easy-to-use, self-navigating system that generates preregistered spatial data in near real time.
SPIN delivers better than 3cm accuracy with a resolution as fine as 1cm as it records more than 200,000 measurements per second. With a 270-degree field of view, the LiDAR-based system generates unprecedented 3-D detail while maintaining a Class 1 Eye Safety Rating.
“Indoor environments pose unique challenges for laser scanning with traditional static systems,” says Sharad Oberoi, Ph.D., Sanborn technical development manager and head of the R&D team that designed and built SPIN. “SPIN navigates autonomously in close-quarter environments and yields highly accurate results 20 times faster than a static system.”
SPIN overcomes the time- and resource-consuming constraints of static systems by traveling at speeds of up to 50cm per second. The platform generates 2-D floor plans and 3-D models of unknown indoor environments without preplanned trajectory programming. It can avoid obstacles–including humans–in real time without intervention, and requires no targets within the scene.
Processing time for a 2-D floor layout is approximately equivalent to scanning time, while 3-D point cloud processing requires approximately 2.5 times scanning time. Dual LiDAR sensors synchronize with an onboard 3-axis digital gyroscope, odometer and integrated depth camera to produce superior 3-D scene models. The output product is delivered in standard formats–LAS, ASCII and BIN.
Sanborn will demonstrate the SPIN platform next week, April 15-17, at the annual SPAR International 3D Measurement & Imaging Conference at the Broadmoor Hotel & Resort, Colorado Springs, Colo. Visit booth 611 to learn more.
