3D Scanning Brooklyn While Rollerblading

The author created a device called "Helmdar" by combining rollerblading, LiDAR, and smartphone AR technology to scan urban environments while rollerblading. Helmdar fuses LiDAR data with the phone's 6DoF pose tracking data to generate 3D point cloud maps. The author shares the creation process, software implementation, and stunning 3D scans of Brooklyn at night, showcasing a unique urban exploration method and data visualization technique.
