64-channel LIDAR sensor RS7

3Dfor mappingfor surveying

Overview
The CHCNAV RS7 is a handheld real‑time 3D LiDAR SLAM scanner designed for interior surveying, architectural documentation and BIM-related workflows. It combines high-rate LiDAR, a high‑precision IMU and SLAM/INS fusion to deliver stable mapping in feature-poor or confined indoor environments.

Highlights

• High-rate LiDAR up to 1.15M pts/s with 360° × 189° ultra-wide FOV (64 channels).
• High-precision IMU with bias instability better than 0.5°/h for reliable motion tracking.
• Dual HD imaging system with Sony binning technology for improved low-light color capture.
• Expandable hardware interface and SDK plus device-to-cloud workflows (CHCNAV CoCloud).

Main features

• INS + SLAM fusion for robust mapping in long corridors, staircases and repetitive spaces.
• Dual-return LiDAR capability (single: 576k pts/s; dual: 1,152k pts/s) to capture fine structural detail.
• HD color imaging and CHCNAV HPGS 2.0 engine supporting 3D Gaussian Splatting for photorealistic reconstructions.
• Open interfaces for customization, peripherals and third‑party integrations.

Benefits & performance

• Stable trajectory estimation in GNSS‑denied interiors thanks to high-precision IMU and SLAM fusion—minimizes drift in feature-poor areas.
• Ultra-wide FOV and high scan rate capture ceilings and confined volumes without repeated setups, speeding up site surveys.
• Cloud-ready pipeline (CoCloud) enables one-click upload, automated processing to point clouds, meshes and 3D Gaussian Splatting outputs, simplifying delivery for BIM and design teams.

Typical use cases

• Architectural and interior surveys, renovation documentation and existing-conditions capture for BIM.
• Interior design workflows and asset documentation.
• Public safety, forensic scene documentation and cultural heritage recording.

Workflow & ecosystem

• Field capture with RS7 → upload to CHCNAV CoCloud → automated processing → deliverables: point clouds, meshes, 3D Gaussian Splatting models.
• Open SDK and hardware interfaces for customized accessories and integration into survey or BIM toolchains.
