Product Features:

The BLK2FLY is the easiest and fastest way to scan indoor and outdoor areas that require a UAV. With powerful autonomous technology, the BLK2FLY is easy to use with simplified operation. Unfold the scanner, set it on the ground or floor, fire up your iPad, turn on the BLK2FLY with the push of one button, and you’re ready for takeoff. It is fully compatible with the Leica Geosystems Cyclone suite of Reality Capture software as well as Reality Cloud Studio, powered by HxDR, offers unprecedented scanning agility to reality capture users in industries worldwide.

For a detailed product overview, please visit the Leica BLK2FLY product page.

With a 5-camera vision system and a dual-axis LiDAR scanner that captures 420,000 measurement points per second, the BLK2FLY is ready to take on any project. Fully integrated sensors – radar, LiDAR, cameras, and GNSS – enable advanced obstacle avoidance and heightened spatial awareness to ensure the BLK2FLY always flies safely and takes the most optimal flight path to capture data evenly and quickly. Simply transfer data with USB-C or WLAN connectivity.

Leica Cyclone REGISTER 360 PLUS (BLK Edition) Subscription

Leica Cyclone REGISTER 360 PLUS (BLK Edition) is a simplified version of Leica Geosystems Cyclone REGISTER 360 PLUS that features an intuitive UI, guided workflows and an easy process for sharing data downstream with more advanced tools like JetStream and TruView. Or export your point clouds as a standard E57 file or Autodesk's native RCP file format. Cyclone REGISTER 360 PLUS (BLK Edition) is optimized for the BLK2FLY and provides streamlined workflows to assist new users and speed up the process for experienced users.  

Reality Cloud Studio, powered by HxDR

Reality Cloud Studio is Hexagon’s cloud-based application for reality capture data storage, automated meshing and registration, advanced visualization, and up-to-the-minute collaboration. Simply upload your BLK2FLY data directly from the scanner using Reality Cloud Studio’s browser-based UI and work with your data immediately in the field. 

Software options for every kind of project

For larger projects or existing Cyclone users, Leica Geosystems Cyclone REGISTER 360 PLUS and Cyclone FIELD 360 are also available to help register your scans together and view scan data and imagery in real-time.
