CHCNAV RS7 Handheld SLAM LiDAR system for indoor and underground 3D mapping
CHCNAV RS7 Handheld LiDAR SLAM Scanner
Real-Time 3D Indoor Mapping with Deep INS + NIC-SLAM
The CHCNAV RS7 is a professional-grade handheld LiDAR SLAM scanner designed for fast, high-density indoor 3D mapping. Built on CHCNAV’s navigation-grade INS and third-generation NIC-SLAM algorithm, the RS7 delivers stable, drift-controlled trajectory performance in corridors, stairwells, and multi-level buildings.
With up to 1.15 million points per second, an ultra-wide 360° × 189° field of view, and dual 12MP HD cameras, the RS7 captures complete, colorized point clouds in a single walk-through — no tripod, no targeting, no manual angle adjustments.
Deep INS + SLAM Fusion for Reliable Mapping
Unlike consumer-grade handheld scanners, the RS7 integrates a tactical-grade IMU (0.5°/h bias instability) with real-time SLAM correction.
This enables:
• Stable trajectory control in feature-poor environments
• Reduced drift in long corridors
• Accurate multi-floor alignment
• Distortion-free stairwell scanning
CHCNAV’s NIC-SLAM (Navigation-grade INS Core SLAM) algorithm deeply fuses high-rate inertial data with SLAM poses to maintain mapping continuity in complex indoor spaces.
High-Rate LiDAR & Ultra-Wide Coverage
• Up to 1.15 million pts/sec
• 360° horizontal × 189° vertical FOV
• No blind zones
• No manual aiming required
The extended vertical field of view captures ceilings and overhead structures in a single pass — ideal for industrial facilities, parking garages, commercial buildings, and infrastructure environments.
High-density point clouds improve automated feature extraction accuracy (>95% in supported workflows)
HD Colorization & 3D Gaussian Splatting
The RS7 integrates dual 12MP HD cameras with Sony binning technology for improved low-light performance.
Features include:
• Sharper imaging in underground or dim environments
• HPC color optimization engine
• Mesh modeling with enhanced color richness
• 3D Gaussian Splatting (3DGS) output via HPGS 2.0
The result: visually realistic digital twins with precise geometric detail.
Device-to-Cloud Workflow with CoCloud
The RS7 is fully integrated with CHCNAV CoCloud:
• One-click data upload
• Automatic cloud processing
• No high-end workstation required
• Outputs: Point Cloud, Mesh, 3DGS
Field-to-office workflow is streamlined — even processing from a smartphone via WiFi or LTE module
Expandable Architecture & SDK Support
The RS7 features an open hardware interface and SDK, enabling integration into:
• Robotics platforms
• Unmanned deployments
• Inspection systems
• Custom software environments
Expansion interfaces include:
• Ethernet (100 Mbps)
• XT30 power interface (long-term unmanned deployment)
• USB-C power bank support
• MAVLink & ROS compatibility
This makes the RS7 suitable for automation, robotics integration, and advanced industrial workflows
