AUTOMATED GROUND CONTROL
FOR HOVERMAP™

UNRIVALED SLAM ACCURACY WITH
AUTOMATED GROUND CONTROL

Emesent’s Automated Ground Control is an innovative feature that further increases the accuracy of Hovermap point clouds and enhances the capabilities of its SLAM-based mapping. It enables new scanning opportunities and use cases, including long, large, and feature-poor assets such as roads, stadiums, and tunnels, previously a challenge for SLAM-based mapping.

Using machine learning, Ground Control automatically detects reflective ground control targets and uses these to both georeference the point cloud and improve accuracy.

WHY USE AUTOMATED GROUND COUNTROL

IMPROVED LOCAL AND GLOBAL ACCURACY

Using control points as constraints improves SLAM accuracy, removing drift or slips to deliver survey grade results.

EXTEND THE CAPABILITIES OF SLAM

SLAM Robustness is increased with control points, allowing you to scan long, linear assets and large or feature-poor environments that were previously challenging for SLAM-based systems.

AUTOMATED GEOREFERENCING

Automated georeferencing via non-rigid transformation to survey control accurately positions
and improves the point cloud.

REDUCE MANUAL ERROR

There is no need to manually locate targets in the point cloud or enter survey coordinates. Targets are automatically detected, and coordinates can be dragged and dropped into the processing workflow, saving time and reducing the risk of manual data entry error.

NON-STOP SCANNING FOR A STREAMLINED WORKFLOW

Automated target detection enables you to run continuous scans without the need to stop and place the Hovermap on each target. Whether a walking or vehicle-mounted scan, Emesent Automated Ground Control enables you to streamline your workflow.

GET THE FULL PICTURE WITH EASE

Easily and accurately merge multiple scans to get a complete picture, with minimal manual processing.

STREAMLINED
WORKFLOW

PLACE YOUR TARGETS

No more fading painted crosses or easily damaged foam spheres! Emesent’s ground control targets are durable and easily placed, and left in place for repeated scanning. Emesent’s spigot-mounted discs are available, or the reflective disc targets can easily be sourced or made.

SURVEY THE TARGETS

Use a total station or GPS rover to survey in new target locations. Placing Emesent’s spigot-mounted targets into existing survey collars ensures the target centers coincide with existing survey prism locations, avoiding the need to resurvey.

CONDUCT YOUR
NON-STOP SCAN

Machine learning is used to detect targets automatically in the scan during processing, so there is no need to stop or place Hovermap on the target, minimizing your scan time.

PROCESS THE DATA

Drag-and-drop the raw scan data and survey coordinates into Emesent’s processing software. Ground Control automatically detects the survey targets and applies a non-rigid transformation of the point cloud, giving you the most accurate results.

CONFIRM THE RESULTS

Processing can be run automatically end-to-end without interaction, or the target detection and constellation matching results can be visualized in Emesent’s point cloud viewer for confirmation or adjustment.

OUTPUT SURVEY GRADE RESULTS

An accurate, georeferenced Hovermap point cloud is ready for use.

ACHIEVING SURVEY GRADE WITH SLAM BASED LIDAR MAPPING

Watch this on demand webinar to hear from Emesent CEO and Co Founder Dr Stefan Hrabar and Emesent Technical Sales Manager Jordan Herrmann on how the Automated Ground Control feature revolutionizes mobile mapping and provides unrivaled SLAM accuracy and workflow efficiencies.

EXPLORE THE INACCESSIBLE WITH
HOVERMAP ST

Hovermap ST is the next generation in mobilemapping payloads, with a tough, lightweight, IP65weather sealed design enabling valuable datacapture in previously inaccessible areas.

This powerful combination of precisionengineering, world-leading SLAM algorithms, androbust drone autonomy capability provideaccurate LiDAR mapping for as-builts, surveys, orinspections.

Equally capable above ground or underground,indoors or out, Hovermap ST can easily beswitched from a drone flight to a walking, vehicle-or backpack-mounted scan, providing theversatility needed to capture data anywhere.

Autonomous Waypoint Mode provides beyond line of sight flight through Smart Waypoints and Guided Exploration. Simply tap on the map to set smart waypoints, and Hovermap ST takes care of the rest, navigating to the waypoints, mapping the area, and keeping itself and the drone safe from obstacles.
