Technical Specification
CHCNAV RS7 SLAM Scanner
CHCNAV RS7 – fast handheld SLAM for buildings and interiors
The RS7 is CHCNAV’s tool-grade handheld LiDAR SLAM scanner for architecture and interiors. A 1.15 million pts/s laser, a 360° × 189° field of view and a high-grade IMU capture rooms, stairwells and corridors completely in one walk.
Dual HD cameras, 3D Gaussian Splatting and one-click CoCloud processing turn scans into colour point clouds, meshes and photoreal models.
Stable tracking where SLAM usually struggles
Long corridors and multi-level staircases have few geometric features. The RS7’s IMU, with bias instability better than 0.5°/h, keeps motion tracking stable in exactly those places, so SLAM results stay complete. The ultra-wide vertical FOV captures ceilings and corners without tilting the scanner.
Why the RS7 suits indoor work
High-grade INS
Bias instability <0.5°/h for reliable tracking in feature-poor spaces.
Ultra-wide FOV
360° × 189° captures floors, walls and ceilings in one pass.
High-rate LiDAR
64 channels, 576k pts/s single / 1.15M pts/s dual return.
HD colour
Dual cameras with binning for sharper colour in low light.
Gaussian Splatting
HPGS 2.0 builds photoreal 3D scenes alongside the point cloud.
Expandable + cloud
Open hardware interface, SDK and CoCloud device-to-cloud workflow.
Reliable mapping in corridors and stairwells
The RS7 fuses a high-precision IMU (500 Hz, 0.5°/h gyro bias instability) with SLAM so trajectories stay stable even in feature-poor environments. The result is a complete, accurate scan of every floor, with relative accuracy under 1 cm and repeatability under 2 cm.
- Absolute <3 cm, relative <1 cm
- Repeatability <2 cm
- GNSS L1/L2/L5 for outdoor georeferencing
Everything in one walk
A new-generation 64-channel laser captures up to 1.15 million points per second, recording fine objects and surface textures. With 360° × 189° coverage you capture ceilings and corners without manually changing the scanner angle.
Pixel-level reality
Dual HD cameras with Sony binning deliver sharper colour in dim interiors. CHCNAV’s HPGS 2.0 engine builds 3D Gaussian Splatting models that combine visual realism with precise geometry – ideal for heritage, real estate and design reviews.
Upload once, results ready
An open hardware interface and SDK let you extend the RS7. With CHCNAV CoCloud, field data uploads in one click and processing runs automatically – point clouds, meshes and 3DGS results are ready when you are back at the office. CoProcess adds CAD tools for drafting.

RS7 FAQ
RS7 or RS10?
The RS7 is built for interiors: faster scanning, a wider vertical view and 3D Gaussian Splatting. The RS10 adds survey-grade RTK for outdoor, georeferenced, loop-free work.
How long does a battery last?
About 150 minutes from the 47.5 Wh handle battery (lab value at 25 °C).
What is 3D Gaussian Splatting?
A photoreal 3D scene representation. The RS7’s HPGS 2.0 engine builds it from the scan and images, so you get a realistic walk-through as well as measurable geometry.
Do I need a powerful PC?
Not necessarily – CoCloud processes data in the cloud after a one-click upload. CoPre and CoProcess are available for desktop processing.
