What Is a Mobile 3D Laser Scanner?
The Short Answer
A mobile 3D laser scanner is a reality capture instrument that collects millions of measurements on the move to create detailed three-dimensional models. Instead of using static tripod setups, operators can capture entire environments simply by walking or driving through a site, providing rapid documentation for large-scale construction and infrastructure projects.
How It Works
The instrument utilizes advanced sensor fusion—combining high-speed LiDAR, visual SLAM, an internal IMU, and GNSS positioning—to accurately map its surroundings while in motion. As the operator moves, the system captures up to 640,000 points per second across a complete 360° horizontal and vertical field of view to generate a dense, colorized point cloud. Integrated software like Collage Web allows teams to visualize, process, and share these mobile datasets directly via the cloud.
Why Mobile 3D Laser Scanners for Construction
Topcon mobile scanners accelerate reality capture by removing traditional positioning constraints. Software integration allows teams to quickly compare as-built conditions against BIM models, track progress, and safely map complex or GNSS-denied environments like tunnels and building interiors. This rapid data collection and cloud collaboration help teams make faster, more informed project decisions.

Topcon Mobile Scanner FAQs
What are Topcon mobile 3D laser scanners, and how do they work?
They use sensor fusion — high-speed LiDAR, visual SLAM (simultaneous localization and mapping), an internal IMU, and GNSS positioning — to build a 3D point cloud while you simply walk or drive through a site, instead of setting up on a stationary tripod like a traditional scanner.
Which mobile scanner models does Site Precision carry?
The CR-M1 (a mobile mapping system), the CR-S1 and CR-S2 (portable SLAM scanners with different range/weight trade-offs), and the CR-H1 (a handheld unit that pairs with an iPhone).
How do I know which mobile scanner is right for my project?
It comes down to site size and environment. Large sites, roadways, or multi-building corridors favor the CR-M1 or the CR-S1’s longer 394 ft range; tight interiors or fast walkthroughs suit the lighter CR-S2 (2.87 lbs) or the CR-H1, which runs on just an iPhone. Your Site Precision rep can help match the model to your typical project.
Do these scanners work in areas without GPS signal, like tunnels or parking garages?
Yes — the CR-S1, CR-S2, and CR-M1 use SLAM-based positioning (MLF-SLAM, VSLAM, and RTK-SLAM) rather than relying solely on GNSS, which is what makes them suited to GNSS-denied environments like tunnels, mines, and underground spaces.
How accurate are Topcon's mobile scanners?
It varies by model: about 1/8 in for the CR-M, roughly 3/8” relative accuracy for the CR-S1, about 3/4” relative accuracy for the CR-S2, and 3/8 in absolute accuracy via RTK for the CR-H1.
What's the difference between mobile scanning and traditional terrestrial/tripod scanning?
Mobile scanners capture data continuously as you move, eliminating the multiple tripod setups and point-cloud registration steps static scanning requires. Terrestrial scanners generally hold a slight accuracy edge from a single fixed viewpoint, so the trade-off is speed and coverage versus maximum single-point precision.
What does a mobile scan actually produce?
A dense, colorized 3D point cloud of the site, viewable in real time on the field controller during capture, and exportable in standard formats like LAS and e57 for your CAD, BIM, or GIS software. The point cloud can then be used to create deliverables such as 2D floor plans, 3D BIM models, surface meshes, topographic maps, immersive 360° walkthroughs, and more.
What software works with the mobile scanner data?
Field capture runs through MAGNET Flow (CR-S1/CR-S2), Onami Field Software (CR-M1), or PIX4Dcatch (CR-H1), and all of it can be published to Topcon Collage Web for cloud-based team collaboration and viewing. Raw point cloud data is compatible with the majority of CAD and BIM softwares.
Can I use a mobile scanner for stockpile or volume measurements?
Yes — stockpile and volume calculations are a stated use case for both the CR-S2 and CR-H1, alongside their broader mapping and documentation roles.
How much does a Topcon mobile scanner cost?
Pricing depends on the model and how it’s configured for your workflow, so we don’t publish a flat number. Reach out and we’ll walk through your project type and put together a quote.
Does Site Precision provide training on these scanners?
Yes, every purchase comes with on-site training from our experts, plus direct support from our team as your local Topcon dealer.
Can I demo a mobile scanner before buying?
Contact your Site Precision rep, we’re happy to run a live demo on your site or at our Grand Rapids facility so you can see the workflow firsthand before deciding.
