XGRIDS Lixel L3 claims 5 mm spatial capture accuracy at INTERGEO

XGRIDS introduced Lixel L3 at INTERGEO 2026, a handheld spatial scanner the company says delivers validated 5 mm relative accuracy — and about 2.5 cm real-time absolute accuracy — by fusing LiDAR, true-color 4K HDR vision, integrated RTK, and a built-in display. From one scan it outputs true-color point clouds, meshes, and photorealistic 3D Gaussian Splatting models (company).

HARDWARE desk — same-day company primary on a field spatial scanner that tries to ship survey-grade geometry and photorealistic 3DGS from one handheld capture pass.

Accuracy, as the same wire has it: Lixel L3 achieves 5 mm relative accuracy, demonstrated against measured ground truth in a documented test, and about 2.5 cm real-time absolute accuracy. Relative accuracy is how tightly points in the scan sit next to each other — 5 mm is about the thickness of a pencil lead. Absolute accuracy is how well that scan sits on the real-world map; 2.5 cm is about an inch. The official product graphic’s footnote says the test ran in a designated 500 m² environment — about 5,400 square feet — with accuracy reported at 1σ. 1σ means one standard deviation: most of those test measurements, as the company frames it, fell inside that band.

Hardware, still company: the L3 fuses a high-accuracy LiDAR, a true-color vision system, an integrated RTK receiver, and a built-in 4.3-inch display into one handheld unit. LiDAR is laser rangefinding — it times laser pulses to measure 3D shape. The vision system is a 1/1.3-inch CMOS 4K HDR camera, meaning a large imaging sensor that shoots high-resolution, high-contrast color. RTK is real-time kinematic positioning: a high-precision GPS-style fix that uses a nearby reference station. The company says an integrated SLAM system keeps the scan stable, and real-time vision-aided localization plus leveling optimization help control drift on longer walks. SLAM means simultaneous localization and mapping — the scanner tracks where it is while it builds the map.

Outputs from a single scan, company: a true-color point cloud, a detailed mesh, and photorealistic 3D Gaussian Splatting models. A point cloud is a dense set of measured 3D points. A mesh is a surface stitched from those points. 3D Gaussian Splatting, or 3DGS, is a way to build a photorealistic 3D scene from photos and scans — you can move through it like a place, not just a still picture. The company says captured data can be processed locally.

Software handoff, still company — attribute, do not desk-verify: as 3DGS moves into production, Autodesk has introduced support for 3DGS in 3ds Max and Trimble has integrated it into SketchUp. XGRIDS’ proprietary LCC2 format is among the early 3DGS formats those established platforms support, the company says, so photorealistic assets can go into AEC — architecture, engineering, and construction — plus film, entertainment, and virtual production.

Throughput, company: L3 typically covers around 100 square meters in 10 minutes for high-accuracy data and photorealistic 3D models — about 1,100 square feet. The company says that makes it suited to large, complex sites.

Field features, still company: the 4.3-inch display shows scan status, trajectory, and coverage. Map fusion aligns multiple scans without preset control points — the survey markers crews usually place first. Privacy protection can blur faces and license plates.

Named voice on the release: Sunny Liao, director of international sales and marketing at XGRIDS. He says 5 mm relative accuracy only matters if it holds up in the field and the data can go straight into BIM — building information modeling, the 3D model contractors and architects share on a job. His quotes are color only beyond that attributed line and stay in Sources.

Plain English for the rest of the card: LiDAR = laser rangefinding that measures 3D shape. RTK = high-precision GPS-style positioning. SLAM = tracking position while mapping. 3DGS / Gaussian Splatting = a way to build photorealistic 3D scenes from photos and scans. point cloud = a dense set of measured 3D points. mesh = a surface stitched from those points. relative accuracy = how tightly scan points sit next to each other. absolute accuracy = how well the scan sits on the real-world map. BIM = building information modeling, the shared 3D job model. INTERGEO = the geospatial trade show. 1σ = one standard deviation on the company’s test.
