Why It Stands Out
A tool-grade handheld scanner built around the things that actually fail in indoor LiDAR work
Most handheld SLAM scanners struggle in three places: feature-poor corridors where the device drifts, fine indoor details that come out blurred, and dim spaces like underground parking where images go dark. RS7 was designed specifically to fix those three problems.
A tactical-grade IMU keeps SLAM stable when geometry runs out. A new-generation LiDAR with 6× the point density of typical handhelds preserves fine detail at walking speed. And Sony binning technology in the dual 12 MP cameras keeps imagery sharp in low light.
- Tactical-grade IMU with 0.5°/h bias instability (20× better than consumer-grade)
- 1.15 million pts/s with 360° × 189° FOV — no aiming required
- Dual 12 MP HD cameras with low-light Sony binning technology
- Open SDK and 100 Mbps Ethernet for robotics and automation
Key advantages
RS7 delivers practical field benefits for architects, surveyors, BIM teams, public safety units, and digital twin specialists working in real, complex indoor environments.
Walk-and-Scan Simplicity
No aiming, no stopping, no manual angle adjustments. The 360° × 189° ultra-wide FOV captures ceilings, floors, and corners in a single walk-through.
High-Density Point Clouds
1.15 million points per second produces 6× the density of older handhelds at the same walking speed, preserving fine geometry, edges, and texture detail.
Sharp Imaging in Low Light
Dual 12 MP HD cameras with Sony binning technology produce clearer colorized point clouds in underground parking, basements, and other dim interior spaces.
Device-to-Cloud Workflow
Upload field data with a single click via CoCloud. Processing runs automatically. No workstation, no software install — just a phone.
Open Platform for Integration
Open SDK, 100 Mbps Ethernet, MAVLink, and ROS support let you integrate RS7 into robot dogs, mobile mapping platforms, and custom automation workflows.
Tactical-Grade INS + NIC-SLAM
Stable trajectory where other handhelds drift
RS7 ships with a tactical-grade INS that delivers 20× better gyro bias stability and 150× better accelerometer bias stability than typical consumer-grade IMUs found in entry-level handhelds. In pure-INS testing, trajectory stays within 1 cm over one minute while consumer-grade drifts more than 10 cm.
CHCNAV’s third-generation NIC-SLAM (Navigation-grade INS Core SLAM) algorithm deeply fuses low-frequency, high-precision SLAM poses with high-rate INS attitude data, with mutual correction running continuously. The result: complete, undistorted scans of multi-floor corridors and ultra-high stairwells with no overlap inconsistency.
- Gyro bias instability: 0.5°/h (20× improvement)
- Gyro random walk: 0.01°/√h (27× improvement)
- Multi-floor stairwells captured distortion-free
- No trajectory-drift worries, even for first-time users
High-Rate Scanning & Ultra-Wide FOV
6× the point density. 60% more vertical coverage. Zero manual aiming.
The new-generation LiDAR captures up to 1.15 million points per second across 64 channels — six times the point density of typical 200,000 pts/s handhelds at the same walking speed. Fine objects, surface textures, and edge details that previously came out blurred are now resolved cleanly.
The ultra-wide 360° × 189° field of view covers everything around and above you in a single pass — a 60% larger vertical FOV than legacy 60° designs. No more blind zones above the device, no need to tilt or aim.
High density also pays off downstream: dense point clouds enable over 95% automated feature extraction accuracy in processing software, dramatically reducing manual cleanup time.
HD Colorization & Pixel-Level Reality Rendering
Sharp colorized point clouds, mesh models, and 3D Gaussian Splatting output
Two 12 MP HD cameras with Sony binning technology deliver noticeably sharper imagery in low-light conditions — underground parking garages, basements, and unlit interior spaces where typical handhelds produce noisy, muddy colorization.
CHCNAV’s proprietary ISP optimization improves HPC HD colorization with a 40% improvement in color saturation and higher-accuracy mesh modeling. The result is reality-grade textures suitable for client deliverables and digital twins.
For the next level of visual fidelity, the CHCNAV HPGS 2.0 engine generates 3D Gaussian Splatting models directly from your RS7 capture — combining photoreal visual quality with precise geometric detail for VR, marketing, and immersive documentation.

RS7 FAQ
What is the CHCNAV RS7 used for?
RS7 is a handheld 3D LiDAR SLAM scanner designed for indoor and underground mapping workflows including architectural surveying, BIM and as-built documentation, interior design and renovation, public safety and forensic investigation, cultural heritage preservation, parking structures, tunnels, and digital twin creation.
What makes the RS7 reliable in feature-poor environments?
RS7 combines a tactical-grade IMU with 0.5°/h gyro bias instability and CHCNAV’s third-generation NIC-SLAM algorithm. The tight INS + SLAM fusion supports stable motion tracking in environments with limited geometric features such as long corridors, multi-floor staircases, and repetitive interiors where pure SLAM systems typically drift.
How accurate is the CHCNAV RS7?
CHCNAV specifies RS7 absolute accuracy at less than 3 cm RMS in both horizontal and vertical directions, relative accuracy under 1 cm, and repeatability under 2 cm. These figures are measured under laboratory test conditions; real-world results depend on environment, route planning, and loop closure quality.
How does the RS7 compare to other handheld SLAM scanners?
RS7 combines a high-speed LiDAR up to 1.15 million pts/s, a 360° × 189° ultra-wide FOV, a tactical-grade IMU with 0.5°/h bias instability, dual 12 MP HD cameras with Sony binning for low-light performance, and 3D Gaussian Splatting output support. Together these capabilities cover three common handheld weaknesses at once: drift in feature-poor spaces, blurred indoor detail, and poor low-light imagery.
How is the RS7 different from the CHCNAV RS10?
RS7 is designed for indoor and underground capture in GNSS-denied or feature-poor environments. RS10 integrates RTK with SLAM to support large-scale outdoor mapping and absolute georeferenced deliverables across wider areas. Choose RS7 for indoor and infrastructure work; choose RS10 when projects require RTK accuracy across both indoor and outdoor terrain.
What is the operating time on a single battery?
CHCNAV rates the RS7 at approximately 150 minutes of operating time per battery at room temperature. Batteries are housed in the smart handle, making hot-swapping straightforward between scans.
Does the RS7 support 3D Gaussian Splatting output?
Yes. The CHCNAV HPGS 2.0 engine generates 3D Gaussian Splatting models from RS7 capture for real-color scene reconstruction. Alongside standard point clouds and OSGB/OBJ mesh models, 3DGS output is exported in PLY format and is well suited to immersive VR walkthroughs, client presentations, and high-fidelity digital twins.
Can the RS7 be integrated with robots and automation platforms?
Yes. RS7 supports base-mounted expansion, an open SDK, and a 100 Mbps Ethernet port with MAVLink and ROS protocol support. An XT30 power input is provided for long-term unmanned deployment.
