The Leica BLK2FLY is an autonomous flying laser scanner with advanced obstacle avoidance for easy reality capture from the sky. It captures building exteriors, structures, and environments to create 3D point clouds while flying.

The BLK2FLY is designed to be easy-to-use: with a few simple taps on a tablet, users can set the BLK2FLY aloft to autonomously scan building exteriors and features, such as hard-to-access areas like rooftops and facades. Deploying the device itself is as easy as unfolding it, switching it on with the press of a button, and placing it on the ground, ready for takeoff.

BLK2FLY autonomous flying laser scanner:

  • 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
  • Advanced obstacle avoidance for superior flight safety
  • Hot-swap battery system
  • Lightweight, portable, easy to use

Users control the BLK2FLY through the BLK2FLY Live App on a tablet for simplified, app-based flying with no need for prior UAV experience. This allows for easy, intuitive control of the BLK2FLY, including live camera feed.

You can select an area within the map on your tablet and the BLK2FLY will create its own flight path to scan it quickly and safely. You can also tap-to-scan: simply send the BLK2FLY to scan a new area by tapping anywhere on the 3D view in the app.

The BLK2FLY Live App also allows you to pilot the BLK2FLY manually with virtual joysticks on your tablet. This critical safety feature always keeps you in control. And for connectivity, the BLK2FLY includes WLAN and LTE communication channels to the tablet for nearly unlimited communication range during flight.

The BLK2FLY makes it easy to get your data into your preferred software and to share your scans with others. It also works seamlessly with other Leica Geosystems sensors and software.

You can directly upload your data to HxDR with automatic conversion to OBJ and cloud-based visualization, and also allow others to access and work with your data, including data download, via HxDR. Or transfer your data to Leica Cyclone REGISTER 360 with USB-C or WLAN for scan-to-BIM workflows.

Autonomous UAV Scanning:

The BLK2FLY intelligently incorporates the environment around it into its flight plans. It keeps the correct distance for ideal scanning and formulates optimized flight routes for return to home.

Full Dome LiDAR Sensor:

The enclosed, full-dome laser scanner onboard the BLK2FLY captures 3D point clouds in all directions.


BLK2FLY takes GrandSLAM technology even further. LiDAR SLAM, Visual SLAM, radar, and GNSS make the BLK2FLY fully autonomous, easy to use, and able to fly safely and accurately on its own.

Complete Scanning with Advanced Obstacle Avoidance:

BLK2FLY uses omnidirectional radar and LiDAR to avoid obstacles for accurate, uninterrupted, and safe scanning.

Hot-Swap Batteries:

The hot-swap battery system keeps you flying. The BLK2FLY will return to you during the scan for new batteries and then continue along with its mission.
