About the BLK2GO Handheld 3D Scanner

How does the BLK2GO handheld scanner work?


The BLK2GO is a compact hand-held laser scanner capable of full 6-DoF positional tracking. It uses SLAM technology which is a unique fusion of LiDAR, color imagery, and Inertial Measurement Unit (IMU) data. This fusion makes this scanner robust and reliable in a variety of environments.

What is the scanning range and accuracy of the BLK2GO?


Range: 0.5-25 meters. BLK2GO scans currently provide 0.6-2cm relative accuracy. We define relative accuracy as what you can measure from a single LiDAR sweep. The accuracy is consistent throughout the range and not affected by sunlight.




Does the BLK2GO have a built-in GPS? Are the scans geolocated?


Currently, it does not have built-in GPS so each point cloud is not associated with any coordinate system. To position a scan within your project, you can use site control to add real-world coordinates. This can be done with a variety of point cloud processing tools.




What’s the battery life?


The BLK2GO comes standard with 3 exchangeable, rechargeable Li-Ion batteries with a battery life of approximately 45-50 minutes each. Batteries can be recharged while you work, and additional batteries can be purchased where needed.




How long does it take to scan? What’s the scanning speed?


Total scan time is largely dependent on the environment. For example, a 10,000m2 office complex might take longer than a 50,000m2 warehouse. The short answer: scan time is about the time it takes to walk through a space. At an average walking pace, you can typically capture 100 -200m2 a minute, at 400,000 points per second. The BLK2GO internal memory allows for 24 hours of scanning (compressed data) / 6 hours (uncompressed data).




How long does it take to setup?


Since the BLK2GO doesn’t need targets or tripods, there’s not much setup involved. Once it is turned on, it takes about 30 seconds for the LiDAR to initialize at the start of each scan.




What is the processing/exporting time?


Scan time to processing time is about 1 to 4. You can choose to process after each scan or wait until the end of your project to batch process them all at once.




Does it run real-time? How do I know if I’ve successfully captured what I needed?


The BLK2GO Live app for iPhone (iOS 12.1 or later) offers live 2D and 3D visualization while scanning, device status and data management




How much can the scanner move?


We recommend scanning at a steady walking pace. You can rotate the device to capture at different angles, but we recommend only having significant movement on one axis at a time. The beauty of a handheld system is that you can move it to capture at unique angles and fit into tight spaces.




Can I scan reflective surfaces?


Mirrors will always reflect but won't necessarily ruin a scan. Extra noise created by reflective surfaces can usually be cropped out afterward.




Does it work indoors and outdoors? What are the lighting requirements?


The BLK2GO is designed to work in both indoor & outdoor environmoents and operates well in a variety of environmental conditions. Light isn’t required for the LiDAR to work, but it helps the camera colorize the scans.




Do I need WiFi to scan or process my data?


WiFi is not needed to scan. BLK2GO and the scanning app has its own connection and does not rely on WiFi to function. All processing is done on device. USB and Ethernet ports are available to transfer point clouds.




Is loop closure required?


The SLAM algorithm does have loop closure, but loop closure is not required to get a good scan. If you are scanning for long linear distances (like multiple city blocks or long winding interior hallways) then we recommend loop back to the starting position to help correct any drift that might have occurred.




What software is included?


The iOS scanning app is free to download and use. Additional registration and point cloud software can be purchased seprately if needed, or you can choose a package option, like the BLK2GO CAD Elite Subscription Package which includes:
- Leica BLK2GO handheld imaging laser scanner
- 1 Year Subscription to Cyclone REGISTER 360 (BLK Edition)
- 1 Year Subscription to CloudWorx Ultimate
- 1 Year Subscription to Jetstream Enterprise
- 1 Year Subscription to one (1) JetStream Connector
- 1 Year Subscription to Cyclone JetStream PUBLISHER.




What point cloud tool can I use?


Tasks like point cloud registration, cropping, sectioning, editing, and viewing can be done in a variety of popular tools already on the market. Our favorite free tools are CloudCompare & Autodesk ReCap. The BLK Leica Software which is available and highly recommended is: - Cyclone REGISTER 360 (BLK Edition)
- CloudWorx
- Jetstream - Pointfuse Geo-Plus Vision Lidar suite is also highly recommended if you are in the AEC industry.




How are scans registered?


We recommend using Cyclone 360 to automatically (or manually if needed) register scans. To make registration easier, we recommend capturing about 20% of overlap in each scan. Targets can be used, but are not required.




Are there ways to improve the accuracy?


Yes, our team is always exploring new methods to improve accuracy. The biggest benefit to our solution is that its mobile, easy to use, and the overall workflow is 10x faster than traditional methods. Many of our customers will happily trade mm accuracy for an easier data capture solution.




What about drift?


Drift is an inherent challenge for SLAM-based systems. While drift is not noticeable in small area scans, it may become a problem in larger areas. For large areas, we recommend returning to starting location before finishing a scan to close the loop. This method will help our system correct for drift.




Is the BLK2GO eye safe?


Yes, the LiDAR sensor in the BLK2GO is a class 1 laser product, which is considered the safest kind of laser and will not damage your eyes. According to the manufacturer, the laser has about 0.02% of the power output in a standard 10-watt LED headlamp bulb on a low-beam setting.




What is the level of security and IT?


All captured data stays on the device and is not uploaded to the internet. Data can be transferred to local devices by USB, ethernet, or an external hard drive. Crash reports are only uploaded to Leica servers to help debug any issues users might have.




How can I schedule a demo or try the scanner on a project?


Yes! We understand that many prospective customers feel more comfortable adopting new technology when they’ve had the chance to try it first. Let us know if you're interested in taking the BLK2GO for a test drive and we can happily arrange an on-site demo.
