Kaarta Announces Stencil 2 Mobile Mapping System

Raising the bar for rapid, high fidelity 3D capture and processing


Kaarta Stencil 2 mobile mapping system

October 15, 2018 | Frankfurt, Germany | Intergeo – Kaarta, innovator of real-time 3D reality capture, today announced Stencil® 2, the next generation of its popular real-time, high fidelity 3D mobile scanning and generation system. Stencil 2 improves mapping accuracy and workflow with a new User Interface, GNSS localization, upgraded hardware, Confidence Metrics, and enhanced software intelligence.

Stencil 2 makes real-time operation easy, organized, and intuitive with a new user interface and on-screen keyboard giving users better control over scanning operations, parameter input, and file management. Stencil 2 ships with an iPad tablet to access operations and view real time scanning on the fly.

Stencil 2 records GNSS data for use in loop closure to georegister and geolocate datasets, correcting for drift and further improving the fidelity of large area scans. Kaarta offers an optional GNSS Kit with Emlid Reach RS+ RTK GNSS receiver and custom mounting bracket. Alternatively, Stencil 2 integrates with other NMEA 0183-compliant GNSS systems.

A host of Stencil 2 hardware upgrades include a faster processor, full size HDMI connector for a more robust connection to monitors, and double the on-board storage capacity providing storage for more scans and reducing the need to frequently offload files.

At the heart of Stencil 2 is Kaarta Engine, Kaarta’s patent-pending advanced 3D mapping and localization algorithms. Kaarta Engine’s proprietary approach reduces the drift error of alternative SLAM systems by an order of magnitude.

Confidence Metrics provide immediate feedback on the quality of scans by signaling whether new scan data is registered properly in the existing map, estimating the likelihood of errors and allowing the user to increase the level of confidence by adjusting data collection techniques or adjusting parameters.

Stencil 2 incorporates Kaarta’s latest intelligent mobile mapping advances. Automated Floor Leveling/Sectioning algorithms identify floor structures and smart-scan leveling for better scans and reduced post-processing time. Floor Planner automatically levels, rotates, and generates 2D images of a “slice” from a point cloud, generating 2D floor plans for large interior spaces such as warehouses or stores on the spot and eliminating many steps in the workflow.

Stencil 2 accurately maps exterior and large interior environments quickly and easily with a range of up to 100 meters and a data rate of 300,000 points per second up to 10Hz. Kaarta’s integrated 3D mapping and real-time position estimation allow capabilities not possible with fixed-base scanning systems. Stencil 2 further solidifies the feasibility of mobile mapping as a stand-alone solution while also widening the possibilities of using mobile mapping to complement or augment other scanning methods.

Stencil 2’s ease of use, breadth of applications, and streamlined workflow make it the perfect choice for infrastructure inspectors, surveyors, engineers, architects, facilities planners, security personnel, or anyone who needs an easy way to document the 3D world quickly and dependably.

Stencil 2 is now shipping worldwide. Upgrade packages are available to current Stencil owners.
