Reference Block Set Revopoint MARKER-BLOCK-KIT — alignment and calibration markers for 3D scanners

Revopoint Reference Block Set (MARKER-BLOCK-KIT) is a collection of alignment and calibration markers designed to improve 3D scanning and photogrammetry workflows. The kit supplies multiple marker shapes and sizes—spherical, dome, pyramid, bar strips and adhesive dots—so scanners can register more reference points, stabilise tracking and achieve more consistent frame-to-frame alignment. This helps reduce alignment errors when capturing objects with smooth, reflective or feature-poor surfaces and supports higher repeatability in reverse engineering, inspection and archival capture tasks.

Advantages

The set offers a variety of marker geometries and sizes to adapt to different scanning distances and object shapes. Magnetic spherical, dome and pyramid markers allow quick, stable placement on metal surfaces while adhesive dots provide dense point coverage on non-magnetic materials. Larger pyramids increase long-range visibility and tracking stability, while smaller spheres and domes capture detail during close-range scans. Collectively, these elements improve registration reliability and reduce post-processing alignment corrections.

Suitable for

• 3D scanning of small to medium objects requiring improved alignment and repeatability
• Reverse engineering and CAD model generation where accurate registration is needed
• Quality inspection and dimensional comparison workflows
• Photogrammetry setups that benefit from distributed reference points
• Scanning of smooth, reflective or low-feature surfaces that confuse feature-based tracking

When it may not be suitable

The kit relies on visible markers and, for magnetic pieces, suitable metal mounting surfaces; it may be less useful when scanning large fixed setups where permanently mounted targets are already integrated. For extremely large-scale scans or outdoor environments with strong wind or weather exposure, lightweight adhesive dots and small magnetic markers may shift or detach unless additional mounting measures are used.

• Self-adhesive markers: inner diameter 6 mm, outer diameter 10 mm; quantity for dense coverage
• Material: polypropylene (PP) plastic for markers; magnetic inserts for magnetic types
• Compatibility: designed for use with a wide range of handheld and desktop 3D scanners and photogrammetry systems

How to use

Place magnetic markers on suitable metal surfaces around the object or fix adhesive markers directly to non-magnetic areas to create a distributed reference field. Use larger pyramids when scanning from a greater distance to improve initial acquisition and use spheres or domes for close-range detail capture. Arrange bar markers along elongated features or to preserve axis alignment. Scan the object following the scanner manufacturer’s recommended path, ensuring markers remain visible and do not move during capture. After scanning, use marker-based registration or the scanner’s alignment tools to lock frames to the known marker geometry.

What to consider before purchase

• Whether your objects or workspace include metal surfaces for magnetic mounting
• The typical scanning distance and object size to choose appropriate marker types and placement
• Need for adhesive markers for non-magnetic or curved surfaces
• Compatibility with your scanner’s marker-recognition or photogrammetry software

Usage recommendations

For stable results, combine larger magnetic pyramids for coarse positioning with a grid of spherical/dome markers for fine alignment; attach adhesive dots to areas with no metal and verify marker visibility throughout the scan. Recheck adhesion and magnet contact before long scans and keep a spare set of adhesive markers for reapplication if needed.
