EinScan TRAK Series by Shining 3D: Wireless, Marker-Free 3D Scanning What is the EinScan Trak? The EinScan Trak by Shining 3D is a dual-form, wireless 3D scanning system that combines an optical tracker with a detachable handheld spherical scanner. Operating over a Wi-Fi 6 network, it enables complete marker-free digitisation of large objects alongside high-resolution capture of complex localised geometries, merging both datasets into a single, unified workflow. Surface preparation historically consumes a massive portion of reverse engineering and inspection workflows. Applying and removing positioning markers on automotive chassis, heritage artefacts, or massive industrial castings is inefficient and, in some cases, prohibited. The EinScan Trak Series eliminates this bottleneck. This system combines an optical tracking station with a modular handheld scanner. You map expansive scenes in tracking mode. You unclip the core module for confined, high-detail laser scanning. One project file. Zero target stickers on the object. Dual-Form Architecture: Tracker + Spherical Handheld How does the dual-form system work? The optical tracker monitors the position of the spherical scanner using retroreflective markers built directly into the scanner’s housing. This allows the user to scan large surfaces without placing markers on the object itself. For confined spaces, the scanner detaches and uses surface geometry for tracking. Shop floors demand adaptable hardware. Traditional setups force operators to deploy separate systems for macro-scale volumetric capture and micro-scale detail work. The EinScan Trak consolidates this. Tracking Mode (Large Object Digitisation) The spherical scanner pairs wirelessly with the tracker. You walk the perimeter of the object. The tracker maintains precise spatial positioning by locking onto the scanner's integrated markers. This is engineered for automotive bodies, marine hulls, and large-scale industrial aftermarket modifications. The result is rapid, stable data acquisition across massive surface areas without relying on the object's inherent geometry for alignment. Handheld Scanner Mode (Localised Detail) Deep cavities and complex mechanical components require close-range manoeuvrability. The spherical core detaches from the tracking frame instantly. It transforms into a lightweight, wireless handheld laser scanner. In this mode, the system utilises surface feature recognition for tracking. It requires no line-of-sight to the base station. Operators can jump from large-scale tracking to internal cavity scanning within the same active project. Triple Blue Laser Matrix What scanning modes does the EinScan Trak offer? The system features three distinct blue laser modes: 19+19 crossed laser lines for high-efficiency volumetric capture, 7 parallel lines for ultra-fine edge detailing, and a single deep-feature laser line for probing narrow channels and recessed holes. Different geometries require distinct optical approaches. Shining 3D has integrated specific projection patterns to handle varied industrial topologies. Crossed Laser Lines (19+19): Built for sheer speed. The dense grid of 38 crossing lines maximises point acquisition per frame. It ensures smooth tracking and rapid coverage over broad, undulating surfaces. 7 Parallel Laser Lines: Engineered for edge fidelity. When reverse engineering mechanical components, sharp corners and distinct transition points are critical. This mode concentrates the optical density to capture crisp, high-resolution boundary data. Single Laser Line: The solution for occluded zones. Standard grid patterns struggle to penetrate deep bores or narrow internal channels. The single concentrated laser line reaches into these complex geometries to retrieve reliable spatial data that other profiles miss. True-Colour 5MP Texture Capture Industrial tracking scanners traditionally sacrifice colour acquisition for raw dimensional accuracy. The EinScan Trak breaks this compromise. It integrates a dedicated 5MP high-definition texture camera alongside dual 2MP depth sensors. It captures photorealistic material finishes and precise geometric data simultaneously. This capability is vital for digital archiving, scientific research, and rendering true-to-life assets for AR/VR deployment. You capture the exact mechanical dimensions and the precise surface aesthetics in one pass. Unrestricted Wireless Operation Cables create trip hazards and restrict movement around large subjects. The EinScan Trak operates entirely untethered. Driven by an independent Wi-Fi 6 communication module, the hardware establishes a high-bandwidth LAN instantly at startup. It maintains fluid data transmission up to a 4-metre radius from the tracker. The Hybrid Leapfrog function allows operators to physically move the optical tracker to a new vantage point while maintaining spatial alignment. This effectively creates an infinite scanning volume for massive assets. Environmental tolerance is equally robust. The high-strength carbon fibre chassis houses optics capable of handling up to 110,000 lux of ambient light. It performs flawlessly outdoors in bright sunlight. The intelligent algorithms process difficult materials natively—including highly reflective metallic rims and matte black carbon composites—without the need for dulling sprays. Hot-swappable batteries deliver up to 5.5 hours in tracking mode and 3.5 hours in handheld mode. Downstream Integration: EXMeasure & EXModel Raw point clouds require processing to deliver engineering value. The EinScan Trak ecosystem integrates directly into professional post-processing pipelines. EXMeasure (Inspection): Generates instant colour-map deviations against reference CAD. Operators can isolate specific GD&T parameters—flatness, cylindricity, parallelism—and extract critical volume or area metrics. It generates clean, visual inspection reports for immediate quality control validation. EXModel (Reverse Engineering): Bridges the gap between polygon mesh and parametric CAD. It extracts geometric primitives, generates cross-sections, and facilitates auto-surfacing. You transition from a heavy scan file to a lightweight, manufacturable digital model efficiently.
