It wasn’t long ago that the idea of a laser-scanner that captured as you walk seemed like a dream. Now, it’s a growing market segment with a few brand-new additions: Berkeley-based Greenvalley International has announced two new lidar backpacks, the LiBackpack 50 and LiBackpack D50. Both scanners both feature ranges of longer than 50 meters (hence the name), and feature SLAM for real-time point cloud registration “in a diverse set of natural and built environments.”
