As a higher-performance evolution of the CR-S2, the Topcon CR-S1 Portable SLAM 3D Scanner 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.

Common Questions About the Topcon CR-S1

What is the Topcon CR-S1?
The CR-S1 is Topcon's portable SLAM-based 3D scanner built for larger-scale mobile mapping, combining longer range and tighter accuracy than the CR-S2 in a still-portable form factor.

How does the CR-S1 track its position?
Through multi-sensor fusion — MLF-SLAM, VSLAM, and RTK-SLAM — fusing LiDAR, visual SLAM cameras, an IMU, and GNSS/RTK positioning where available.

How accurate is the CR-S1?
About 3/16", with absolute accuracy under 1 3/16" and relative accuracy under 3/8". With RTK, horizontal accuracy is 5/16" + 1 ppm and vertical is 9/16" + 1 ppm.

What's the CR-S1's range and scan speed?
Up to 394 ft (393.70 ft) at 90% reflectivity, capturing 320,000 points per second.

How much does the CR-S1 weigh?
4.85 lbs (4.85 lbs).

What cameras does the CR-S1 use?
Three 12MP panoramic cameras and two 1.3MP VSLAM cameras — one more panoramic camera than the CR-S2.

What's the CR-S1 best used for?
Topographic mapping, large-scale site surveys, floor plans, 3D modeling, infrastructure assessment, tunnel and mining documentation, and other GNSS-denied environments.

Does the CR-S1 work in tunnels or underground where there's no GPS?
Yes — that's specifically one of its stated use cases. Its SLAM-based tracking doesn't require GNSS, so it holds position accuracy in tunnels, mines, and other underground or enclosed spaces.

What software does the CR-S1 use?
MAGNET Flow for field capture, MAGNET Bridge for processing, with data publishable to Topcon Collage Web for cloud-based collaboration and review.

How is the CR-S1 different from the CR-S2?
The CR-S1 has a longer range (394 ft vs. 230 ft) and tighter relative accuracy (3/16" vs. 13/16"), at the cost of more weight (4.85 lbs vs. 2.87 lbs). It's the better choice for large open sites and infrastructure work; the CR-S2 is better for tight or indoor spaces.

What format does the CR-S1 export data in?
LAS , e57 and other formats compatible with standard CAD, BIM, and GIS software.

Is the CR-S1 a good fit for infrastructure or roadway projects?
Yes — its longer 394 ft range and large-scale site survey capability make it well-suited to infrastructure assessment and other big-footprint projects where fewer stops are needed to cover the same ground.
