CHCNAV RS7
Professional Handheld SLAM 3D Laser Scanner. Master GNSS-denied environments with ultra-stable Deep INS fusion and real-time mapping precision.
CHCNAV RS7: Precision SLAM Scanning & 3D Gaussian Splatting
The RS7 sets a new standard for reality capture by combining a high-density LiDAR sensor with an IMU featuring bias instability better than 0.5°/h. This ensures ultra-stable motion tracking in even the most challenging indoor spaces. Beyond traditional point clouds, the RS7 supports 3D Gaussian Splatting for photorealistic digital twins. Streamline your field-to-finish process with device-to-cloud workflows, making the RS7 the most efficient handheld 3D laser scanner in the PQS Tech lineup.
Key Features
High-Density 3D LiDAR
Experience unparalleled detail with a 1.15M pts/s sample rate. Its hemispherical FOV ensures total coverage of ceilings, floors, and corners in a single pass-no gaps, no rework.
Industrial-Grade Stability
Featuring an IMU with bias instability <0.5°/h, the RS7 delivers ultra-stable motion tracking. Eliminate drift and maintain survey-grade accuracy even in "feature-poor" environments like long hallways or staircases.
Photorealistic 3D Imaging
Equipped with dual 12 MP HD cameras, the RS7 captures crystal-clear textures even in challenging low-light environments. Perfect for generating high-fidelity colorised point clouds and immersive digital twins.
Versatile System Expansion
Built for evolution. The RS7 features an open hardware interface and a comprehensive SDK, allowing your team to integrate custom sensors or develop bespoke workflows tailored to your unique project requirements.
Features
Engineered for complex geometry. The 0.5°/h high-stability IMU ensures seamless motion tracking between floors. Capture complete, vertically aligned 3D data across multi-level sites without losing SLAM initialisation.
Capture everything in a single pass. With a 360° × 189° ultra-wide FOV and a massive 1.15M pts/s scan rate, the RS7 maps ceilings, floors, and confined spaces simultaneously. Eliminate blind spots and manual adjustments for a truly complete 3D dataset.
A scanner that grows with your business. The RS7’s expandable hardware interface and SDK allow for custom sensor integration, while its cloud-ready ecosystem automates data processing for a faster, smarter 3D workflow.
Built for the most demanding sites. The RS7’s IP64-rated housing protects against dust and splashes, while its lightweight (1200g with battery), ergonomic build ensures all-day comfort during complex indoor and outdoor surveys.

How do I choose between the CHCNAV RS7 and the RS10?
The choice depends on your environment. The RS7 is a dedicated handheld SLAM LiDAR scanner optimised for high-precision indoor mapping, specifically designed to handle "feature-poor" areas like staircases and long corridors where other scanners lose tracking. The RS10, however, is a hybrid RTK-SLAM system that adds GNSS capabilities. Choose the RS10 for large-scale outdoor projects requiring absolute georeferencing; choose the RS7 for superior density and reliability in complex, GNSS-denied interiors.
How does the RS7 prevent mapping errors in long corridors or staircases?
Most SLAM scanners struggle in "feature-poor" environments where there aren't enough unique objects to track. The CHCNAV RS7 overcomes this by fusing high-precision Deep INS with a professional-grade IMU 0.5°/h bias instability). This combination provides ultra-stable motion estimation, allowing the scanner to "know" exactly where it is even in repetitive hallways or dark stairwells, resulting in a perfectly aligned, drift-free 3D model.
In which industries is the CHCNAV RS7 most effective?
The RS7 is a powerhouse for GNSS-denied environments across several key sectors:
- Architecture & BIM: Ideal for rapid indoor surveying, renovation planning, and as-built documentation.
- Public Safety & Forensics: Perfect for high-speed, photorealistic crime scene or accident documentation.
- Civil Engineering: Accurate mapping of tunnels, service corridors, and underground utilities.
- Construction: Small-volume stockpiles, staircase mapping, and progress monitoring in enclosed spaces.
- Cultural Heritage: Capturing intricate details for preservation using high-fidelity 3D Gaussian Splatting.
What sets the CHCNAV RS7 apart from other handheld SLAM scanners?
The RS7 is defined by its "no-compromise" specification. While many handheld scanners struggle with data gaps or drift, the RS7 delivers 1.15 million points per second across a massive 360° × 189° FOV, ensuring total coverage in a single pass. When you combine this density with an industrial-grade 0.5°/h IMU and 3D Gaussian Splatting, you get a tool that isn't just faster—it's more stable and produces significantly more realistic digital twins than standard SLAM units.
Is the CHCNAV RS7 difficult to operate for non-specialists?
Not at all. The RS7 is designed to bridge the gap between complex hardware and simple deliverables. By utilising the CHCNAV CoCloud integration, the device offers a "One-Click" field-to-finish experience. Once your scan is complete, data is uploaded directly to the cloud where processing happens automatically. Whether you need a point cloud, a mesh model, or a 3D Gaussian Splatting result, the RS7 handles the heavy lifting, significantly reducing the learning curve for your team.
