From Building to 3D Reality: Fast Indoor and Outdoor Mapping with the Hi-Target LS1 PRO SLAM SCANNER
When surveying a building, collecting complete 3D data is often more complicated than simply scanning the space. Surveyors may need to move between indoor and outdoor environments, work in areas with limited GNSS availability, capture large amounts of point cloud data, and then turn the raw data into usable engineering deliverables.
In a real-world project carried out by Hi-Target partner @scankraft3d, the Hi-Target LS1 PRO Handheld SLAM Scanner was used to capture an entire building, both inside and outside. The project demonstrates how mobile SLAM scanning can simplify reality capture while providing a continuous workflow from field data acquisition to point cloud processing and 3D deliverables.
One Scanner for the Complete Building
The LS1 PRO is designed for complex real-world environments where conventional surveying workflows can require multiple setups or repeated measurements.
Combining LiDAR, vision, RTK positioning and SLAM technology, the LS1 PRO enables mobile 3D scanning while maintaining positioning information throughout the project.
For the ScanKraft3D project, the scanner was used to capture the building interior and exterior as part of one continuous reality-capture workflow.
This approach is particularly useful for buildings and other complex structures where surveyors need to move between open outdoor areas and indoor spaces without constantly changing equipment or workflows.
The LS1 PRO also supports seamless indoor and outdoor scanning in a single project, reducing repeated setup and interruptions during data collection.
High-Speed 3D Data Capture
The LS1 PRO is built for efficient mobile mapping and high-density point cloud acquisition.
With a scanning range of up to 300 m and a point acquisition rate of up to 640,000 points per second, the LS1 PRO can rapidly capture detailed spatial information across large and complex environments.
Instead of relying on point-by-point measurements, surveyors can walk through a building and continuously collect spatial data.
This makes mobile SLAM scanning particularly suitable for:
- Building documentation
- Existing-condition surveys
- Construction verification
- Renovation and retrofit projects
- Industrial facility documentation
- Tunnel and underground environments
- Heritage documentation
- Digital twin projects
The result is a dense 3D representation of the physical environment that can be further processed for engineering and visualization.
SLAM + RTK for Flexible Mapping
One of the key advantages of the LS1 PRO is the combination of SLAM and RTK.
SLAM enables mobile mapping in environments where GNSS signals are limited or unavailable, while RTK positioning provides georeferencing and helps maintain global positioning accuracy.
The LS1 PRO integrates RTK directly into the system without requiring an external bracket or cable. Its published specifications include 2 cm built-in RTK accuracy, with stated absolute accuracy below 4 cm and relative accuracy below 1 cm.
The system also supports free-path scanning with RTK, reducing dependence on closed-loop scanning routes. This can help surveyors work more naturally through complex spaces while maintaining stable positioning.
Real-Time Accuracy Feedback in the Field
Another important part of the LS1 PRO workflow is real-time feedback.
During scanning, the Hi-SLAM App allows users to monitor data and positioning information while working. The system provides trajectory quality visualization and on-device status feedback, helping operators understand scanning conditions as data is being collected.
This is especially valuable for professional surveying projects.
Instead of discovering potential data-quality issues only after returning to the office, operators can monitor the scanning process in the field and make adjustments when necessary.
The Hi-SLAM App also supports real-time coordinate display and field tools such as volume calculation, with Android and iOS support.
From Point Cloud to Engineering Deliverables
The ScanKraft3D workflow also highlights an important part of mobile mapping: data processing after scanning.
Raw point clouds are only the beginning.
Using Hi-LiDAR, LS1 PRO data can be processed and transformed into different types of engineering and visualization outputs.
The software workflow includes:
- Point cloud processing
- Automatic filtering and colorization
- RTK/PPK georeferencing
- Point cloud classification
- Point cloud slicing
- Measurement
- DXF export
- Mesh generation
- 3D Gaussian Splatting
- Engineering analysis
- Volume calculation
Hi-LiDAR is designed as a processing platform covering SLAM processing, architecture, engineering analysis and 3DGS/Mesh generation.
This creates a complete workflow:
Physical Space → 3D Scanning → Point Cloud → Processing → Engineering Analysis → 3D Visualization
Rather than treating scanning and processing as separate stages, LS1 PRO and Hi-LiDAR connect field capture with downstream deliverables.
Multiple Ways to Deploy the LS1 PRO
The LS1 PRO is not limited to handheld scanning.
The system supports multiple operating configurations, including:
- Handheld scanning
- Backpack scanning
- Vehicle-mounted scanning
- UAV-based applications
This flexibility allows the same core scanning technology to be adapted to different project requirements.
For a building survey, handheld operation can provide detailed capture in rooms, corridors and other confined areas.
For larger outdoor areas, the system can be integrated into different mobile scanning configurations to improve coverage and productivity.
Applications Across Surveying and Reality Capture
The ScanKraft3D building project represents one example of how LS1 PRO can be applied to real-world 3D mapping.
The technology can also support a wide range of professional applications.
Building Surveying
Capture existing buildings and generate detailed 3D point clouds for documentation, renovation, BIM workflows and construction verification.
Construction
Collect as-built information and compare physical conditions with design data to support construction management and site verification.
Industrial Facilities
Rapidly document plants, tanks, pipes and complex indoor environments. Point cloud data can support maintenance, retrofit planning and digital twin development.
Tunnel and Underground Surveying
SLAM-based scanning enables mobile 3D mapping in underground and GNSS-denied environments where conventional GNSS surveying can be difficult.
Forestry and Powerline Inspection
Mobile and airborne scanning configurations can be used to capture complex outdoor environments and support infrastructure inspection.
Cultural Heritage
The LS1 PRO can capture detailed 3D information from buildings and heritage sites for documentation, visualization and digital preservation.
Hi-Target currently highlights building surveying, tunnel construction, forestry and powerline applications, and smart cultural tourism among LS1 PRO applications.
A Complete Reality Capture Workflow
The ScanKraft3D project demonstrates how the LS1 PRO can fit into a modern reality-capture workflow.
The value is not only in collecting more point cloud data. It is in connecting field capture, positioning, processing and final deliverables.
With LS1 PRO and Hi-LiDAR, professionals can move from:
Capture faster → Process smarter → Analyze data → Create usable 3D deliverables
For surveying, construction, architecture, engineering and digital-twin applications, this integrated workflow can reduce unnecessary field operations while making captured spatial data easier to process and reuse.
The Hi-Target LS1 PRO provides a flexible approach to mobile 3D reality capture—bringing SLAM, LiDAR, vision and RTK into one workflow from physical space to digital reality.
