Accurate Positioning and Navigation

The full dome LiDAR sensor captures data in all directions creating an immersive point cloud in complex environments. Data collected with the BLK2FLY is highly-precise and georeferenced for applications that need real-world locations. 

  • Allows you to scan hard-to-reach areas like building facades and rooftops
  • Autonomously captures complete scans of building exteriors to create 3D digital twins
  • GrandSLAM sensor fusion of LiDAR, radar, cameras, and GNSS for complete scan coverage, optimized flight paths, and shortest return to home
  • Omnidirectional obstacle avoidance for flight safety and safe scanning
  • Georeferenced point cloud for high-accuracy mapping
  • Hot swap battery system
  • Lightweight, portable, easy to use

The BLK2FLY is ideal for several use cases including construction, BIM, architecture, UAV mapping, and more. The autonomous flight capabilities of the BLK2FLY allow operators of any skill level to collect high-accuracy LiDAR data, opening up several industries and applications previously inaccessible by complex equipment. The BLK2FLY Is highly portable with hot-swappable batteries allowing for all-day missions. 

The BLK2FLY scans building exteriors and structures to create 3D point clouds in real-time, while flying fully autonomous

The BLK2FLY is an easy-to-use drone laser scanner that can be operated by any Transport Canada certified pilot with or without experience.
