CHCNAV RS7 – Handheld 3D LiDAR SLAM Scanner

The CHCNAV RS7 is a powerful and compact handheld 3D laser scanner that combines LiDAR technology, high-precision INS positioning, and SLAM methods into one efficient measurement solution. The RS7 is specifically designed for indoor mapping, BIM documentation, as-built measurements, and demanding sites where comprehensive 3D data is needed quickly.

Measure quickly – even in challenging indoor spaces

The RS7 enables the collection of dense 3D point clouds while moving freely through the environment being measured. The precise combination of INS and SLAM helps maintain stable positioning even in long corridors, stairwells, and other environments where there are few clear geometric features.

Key Benefits

• 64-line LiDAR scanner
• Point collection rate of up to 1,152,000 points/s

• Weight approx. 1.2 kg
• IP64 rating

Efficient LiDAR scanning

The RS7’s new-generation 64-line LiDAR scanner collects up to 1.152 million points per second. The 360° × 189° field of view enables comprehensive measurement of walls, floors, ceilings, and cramped spaces without the need for constant device rotation.

The wide field of view reduces the need for extra measurement rounds and significantly speeds up indoor mapping.

Precise positioning with INS + SLAM technology

The RS7’s precise inertial measurement system and SLAM technology combine motion tracking with 3D environmental mapping. The IMU bias stability is less than 0.5°/h, which helps maintain stable positioning even in featureless environments.

This solution is suitable for, for example, long corridors, staircases, and other sites where maintaining positioning with traditional SLAM measurements can be challenging.

HD images and realistic 3D data

The RS7’s two HD cameras produce high-quality visual data even in challenging lighting conditions. The camera images can be combined with the point cloud, resulting in visually rich 3D data.

CHCNAV’s HPGS 2.0 technology also enables the creation of 3D Gaussian Splatting models. This allows geometric measurement data to be combined with a realistic visual representation of the site.

Smooth workflow from field to office

The RS7’s SmartGo software enables device management, project creation, real-time point cloud viewing, and data management. With the CoPre software, you can perform tasks such as data post-processing, point cloud generation, and 3D modeling.

The produced data can be processed as, for example, colored point clouds, 3D models, and Gaussian Splatting data.

Compact design – efficient work

The RS7 weighs approximately 1.2 kg with the battery, making it easy to carry and use even during longer measurement sessions. The integrated 47.5 Wh battery provides up to 150 minutes of operating time on a single charge.

The IP64 protection and operating temperature of -20 °C to +50 °C make the RS7 suitable for professional measurement use in various indoor and construction site conditions.

The RS7 is suitable for, for example:

• indoor 3D mapping
• BIM and Scan-to-BIM projects
• building documentation
