Topcon CR-S1 Portable SLAM 3D Scanner
Unmatched Speed and Flexibility
The Topcon CR-S1 is a high-performance handheld 3D scanning system built for today’s construction, surveying, and geospatial professionals. It combines advanced multi-sensor fusion (MLF-SLAM, VSLAM, and RTK-SLAM) with LiDAR, panoramic cameras, visual SLAM cameras, and integrated GNSS in a single portable unit. With a scan speed of 320,000 points per second and extended range, it delivers unmatched efficiency for topographic mapping, construction site surveys, progress monitoring, infrastructure assessment, tunnel/mining documentation, forestry analysis, and challenging GNSS-denied or featureless environments—all in a rugged, one-person design.

High-Performance Handheld SLAM Scanning with RTK—Dense Point Clouds, Extended Range, Real-Time Precision, Ready for Tomorrow
As a higher-performance evolution of the CR-S2, the CR-S1 offers increased point-cloud density, extended scanning range, and upgraded panoramic imaging in a single handheld unit. Its multi-sensor fusion (LiDAR + VSLAM + RTK-SLAM) provides stable, survey-grade accuracy even in featureless areas like beaches, forests, or urban canyons—delivering real-time colorized data with minimal setups for one-person efficiency.
Real-time data capture and preview is managed via the MAGNET Flow app (Android/iOS), with advanced SLAM processing performed through MAGNET Bridge. Data publishes seamlessly to Topcon Collage Web for visualization and collaboration, with export capabilities to standard formats (LAS, e57, etc.) for integration with BIM, CAD, GIS, or other preferred software.
