GeoSLAM were invited by Willmott Dixon to be involved with the beginning of this process, by scanning the existing used timber units provided by Carter Accommodation. Using the ZEB Revo RT, Willmott Dixon were able to capture data of all 4 cabins, in 4 minutes, registering over 8 million number of points.
Chartered land surveryors, GeoTerra were invited by the BCRA (British Cave Research Association) to scan the cavern, so they could gain a better understanding of the geological formation. Using GeoSLAMs ZEB Horizon, GeoTerra’s goal was to map both areas accessible to the public and the narrow spaces just big enough to crawl through – a system of caves measuring 300metres long and 50metres wide.
For 40 days, 15 participants set up camp in the Lombrives cave in southwestern France with no clocks or sunlight, and zero contact to the outside world.

Laserscanning Europe | German Dealer
GeoSLAMs German dealer, Laserscanning Europe, were recently tasked with scanning a 70m deep cavity in a mine 500m below the earths surface. Using the ZEB Horizon on a cradle, Laserscanning Europe were able to successfully and safely capture the data, and this is their account of the job.
Data captured by Laserscanning Europe
Scanning with the ZEB Horizon | Words by Laserscanning Europe
The object of measurement is located in the Hattorf/Wintershall mining facility of the company K+S Minerals and Agriculture GmbH. This is a cavity (underground, vertical conveyor system) about 500m below the earth’s surface with a depth of 70m.
The cavity no longer has the original storage volume due to material deposits from years of operation. The environment is dusty and it is expected that material will be deposited within the conveyor system at any time. In addition, the cavity is not accessible to humans from any opening and access is only possible through 1m diameter openings.
The objective was to obtain a three-dimensional survey of the conveyor system with highest possible resolution for inspection of the systems condition. Furthermore, strict compliance with all work safety regulations, with minimal risk for the measuring team, was required.
For this job, a mobile laser scanner was used. Thanks to its specifications, the GeoSLAM ZEB Horizon is ideally suited for the special conditions underground. The scanner is also suitable for surveying a cavity that is only accessible from above through a narrow shaft.
The scanner was mounted on a cradle, which was modified to minimise rotational movements when lowered. A 50m rope was attached to the cradle, which was used to lower the measurement system into the cavity.
Furthermore, trained members of the mine rescue team were on site to provide security and enable the scanner to be lowered and retrieved safely.
Measurement Procedure
01
Preparation of the survey: mounting of the scanner on the cradle and mounting of the rope system for lowering and raising the scanner
02
Starting the measurement at the upper end of the opening to the cavity
03
Lowering of the scanner, 50m deep, while the ZEB Horizon captures data
04
Raising the scanner, 50m high, while the ZEB Horizon captures data
05
Finishing the scanning process at the upper end of the opening to the cavity
06
Ascent from the mine and analysis of the scan data in the office
Workflow of the analysis
Following the survey, the scan data was processed using the GeoSLAM HUB software. The raw data, i.e. the processing of the point cloud from the data of the laser sensor and the IMU, is automated as much as possible. In the case that a scan was not automatically processed (e.g. because few geometric changes are found in the object space), the focus of the SLAM algorithm can be influenced by adjusting various parameters. Once the data has been run through GeoSLAM Hub, a complete point cloud of the cavity is available in .laz format. All other common point cloud formats can also be exported with little effort.
Since the scanner could only be lowered linearly on the rope, the earth deposits shadow smaller areas inside the cavity.
Results
The result of this scanning is impressive. This cavity, which is not accessible to humans, was successfully surveyed with the help of the GeoSLAM ZEB Horizon. The point cloud documents the dimensions of the cavity according to the requirements. Further missions with the GeoSLAM ZEB Horizon with similar objectives are already being planned and implemented.

Mapping WW1 Tunnels in Vauquois, France
The Vauquois battlefield in France tells a little-known story of mining warfare during World War I. This area went through 4 years of combat which saw the hilltop village of Vauquois completely destroyed. In addition, French and German troops dug miles of tunnels under each other’s positions. This meant they could plant explosive mines to ‘bomb’ the enemy from below. Consequently, this bombing left underground WWI tunnels in Vauquois.
The WWI tunnels in Vauquois must be experienced first-hand to understand the difficulties and despair of living deep underground. Moreover, in wet, cold and cramped conditions for days at a time. Of course, not everyone can travel to France and crawl through the remaining tunnels in person. A group of researchers at Virginia Tech brought the battlefield to classrooms and museums with the help of reality capture and virtual reality (VR) technologies.
The WWI Tunnel’s Extensive Cramped Spaces
Combining efforts of the University Libraries, the Department of Visual Arts and numerous other disciplines, the Visualising History team travelled to Vauquois with funding from a federal grant in 2016. Over 10 days, they used traditional static scanning methods to capture details of the battlefield terrain.
However, when they attempted to scan inside the tunnels, their progress slowed down considerably as there were tight spaces that their scanners could not get into, which made the data capture process extremely time-consuming.
Scanning difficult to access areas with the ZEB Horizon
Before their next trip to France, the team acquired a 3D handheld laser scanner, GeoSLAM’s ZEB Horizon, with the hopes of making their time on-site more time efficient.
Due to the ZEB Horizon’s ease of use and speed of capture, the team collected scan data inside the tunnels more than three times faster than with the traditional stationary scanner. The time it took to scan the tunnels was crucial, as they were working on a budget, and the ZEB Horizon enabled them to do more with the time and money they had available. They also used the ZEB Horizon above ground, scanning the narrow trenches, wide bomb craters, and a church foundation.
The ZEB Horizon also proved to be more efficient as its software processes the data into a point cloud quickly. This meant that the team where able to see where data was missing, and go back and collect it, whilst still on-site. This created a much more accurate and complete virtual environment.
The ZEB Horizon was a gamechanger in terms of the speed of data acquisition.
Building the WWI Tunnels with the ZEB Horizon’s datasets
The Virginia Tech team engaged the expertise of students and faculty from numerous departments – Visual Arts, History, Education, Computer Science, Mining, Engineering, and Cinema – to build a life-size model of a tunnel and generate the virtual environment of the battlefield. This allows students wearing VR headsets to ‘walk’ through the scene, experiencing it with both sight and touch.
The speed and accuracy of the ZEB Horizon are game changers for educational and historic preservation VR projects like this because of time and budgetary restraints. VR data processing is extremely time consuming, which means time saved scanning in the field makes grant money go farther in the computer lab. The result is a more realistic and believable experience.
Going further with 3D laser scanning
The Virginia Tech Visualizing History team is not stopping with creating educational experiences from their 3D data collection. They are beginning to apply their VR capabilities to other commercial applications of mobile laser scanning.

Here is an example of a visualisation created in Nubigon using GeoSLAM point cloud data:
SLAM Environmental Pre-sets
Common data capture scenarios, such as UAV, outdoor, indoor, linear, and vehicle, have been characterised in Connect and data processing pre-sets for each environment have been defined. These can be selected at the beginning of the data processing stage allowing this process to be highly simplified.
Closed and Open Loop Georeferencing
Both methods match the scan data from a ZEB Locate system with the GPS data collected from the antenna to georeference the point cloud. When a scan starts and ends in the same place, this is classed as “closed loop”. “Open loop” is when the start and end position of a scan are in different locations. Standard SLAM practices apply to both methods of data collection.
Open Loop SLAM for the ZEB Locate is available on request – let’s talk about it.
Stop and Go Alignment
Common static points are captured during several scans meaning that these datasets can be automatically aligned. A single point cloud is then exported as if the data was captured in a single scan.
Floor Slices
Horizontal and vertical slices can be taken from any location within the point cloud. Horizontal floor slices can also be automatically taken at a given height above the floor as defined in the processing stage.
Change Detection
Mostly used in the construction industry, multiple point clouds can be compared and any areas that have changed are automatically highlighted. Point clouds can also be compared with CAD models – for instance to track progress on a construction site – and PDF reports can be generated to present this information.
Queued Processing
Import multiple .geoslam files into Connect for processing and the scans will be processed in the order they were imported. The size of the queue can be defined by the user.

Coupling with hardware
Some SLAM software algorithms have been made available as open-source on the internet, but they are purely algorithms and not a product that you can take and use off-the-shelf. SLAM is most successful when it is tightly coupled and designed with specific hardware in mind. A generic SLAM cannot perform as well as one that has been specifically designed for a purpose.
Usage in multi-environments
Visual SLAM is closer to the way humans navigate the world, which is why it’s popular with robotic navigation. But in the same vein, vSLAM will have the same image-capture challenges as humans do, for example not being able to look into direct sunlight, or not having enough contrast between the objects picked up in the image. These can be overcome indoors, however, you may need to map a forest, tunnel or urban canyon. While SLAM technologies don’t rely on remote data (meaning you can scan areas where there is no GPS), you do need to ensure the SLAM technology you chose operate well inside, outside, in daylight and darkness.
Real-time data capture
Mapping a property is time-critical. Ideally, you want to make a single visit and gather sufficient data to create a highly accurate 3D model. Ensure the software you choose transforms 3D point cloud data into actionable information in real-time. This allows you to view and interrogate your data whilst still in the field, and make any adjustments, or collect missed data, then and there.
Flexibility and deployment
If you’re trying to map an enclosed environment (e.g. tunnel, mine) or a complex, difficult-to-access space such as a heritage building with tight stairwells and uneven floors, you need to use fully-mobile, adaptable technology. Wheel-based systems, often used with the vSLAM camera, will struggle with access. Handheld devices or LiDAR scanners that can be attached to a drone or pole and still deliver accurate results in a rugged environment are best for navigating hazardous spaces.
Speed and accuracy
While vSLAM is able to provide a qualitative high-level map and sense of the surrounding features, if you’re needing survey-quality accuracy and rich-feature tracking at a local level, you’ll need to consider LiDAR. Cameras require a high-frame-rate and high processing to reconcile data sources and a potential error in visual SLAM is reprojection error, which is the difference between the perceived location of each setpoint
and the actual setpoint.
Quality and distortion
In order to deliver the depth required for high-quality data, a number of depth-sensing cameras are needed with a strong field of view. In most cases, this isn’t possible, especially as cameras with high processing capabilities typically require larger batteries which weigh down airborne scanners, or limit the time of flight. LiDAR is both faster and more accurate than vSLAM, and can deliver detailed point clouds without expensive (and timely) camera processing.
