Small, lightweight, 3D-imaging laser scanner
The BLK360 3D-imaging laser scanner captures
building environments with full-color panoramic images overlaid on a high-accuracy point cloud.
The unit is encased in an aluminum housing, weighs
2.2 lb., measures 4 in. dia. and 6.5 in. tall, and is
designed to be transported in a standard messenger
bag. Scans are initiated by pushing a single button,
and the rechargeable battery can deliver more than
40 full scans. A full scan includes panoramic images
of the space, a laser scan, and a full complement of
thermal images. The scanner has a 60-meter measurement range for full dome scans. A complete fulldome laser scan, 3D panoramic image capture, and
transfer to an iPad Pro takes 3 min.
Once a scan is completed, the devices uses Autodesk's ReCap Pro 360 mobile app to stream image
and point cloud data to an iPad Pro. The app filters

and registers scan data in real time. After capture,
the app makes it possible to transfer point-cloud to
a number of CAD, BIM, VR, and AR applications.
Integrating BLK360 and Autodesk software will
dramatically streamline the reality-capture process,
thereby opening this technology to non-surveying
individuals.
The BLK360 has 64 GB of onboard memory that
will store as many as 100 full scans when operated in
autonomous mode. The scanner acts as its own WiFi
hotspot; there is no need to have WiFi on a jobsite
to capture a scan. The integrated wireless LAN supports the 802.11 b/g/n standards. Note that if you
are using cloud-based collaboration tools you will
need to provide Internet access to transmit your reality capture data back to the office.

three measurements-a horizontal angle, a vertical
angle, and a slope distance from the scanner center to the measured point. This is referred to as a
"polar" measurement. In simple terms, the scanner's
3D accuracy is affected by the accuracy of the polar
measurements. The BLK360 has 3D point accuracies of 6 mm at 10 m and approximately 8 mm at
20 m (1/4 in. at 33 ft. and approx. 1/3 in. at 66 ft.,
respectively), 1 sigma. This makes the BLK360 an
excellent as-built measurement tool, especially combined with its ability to collect as many as 360,000
measurements/sec. and full HDR imagery at the
push of a button.
