High-contrast markers for large-area optical 3D scanning processes and precise object registration

These magnetic black and white dots with a 6 mm diameter were specifically developed for measurement tasks with structured light scanners , optical 3D measurement systems and fringe-projecting scanners that require a clear, high-contrast marking for object registration.
With their larger diameter of 6 mm, these markers are ideal for larger components, increased scanning distances , and metrological applications where stable visual recognition from different viewing angles is important.

The magnetic backing ensures secure, repeatable positioning on metallic surfaces. Ideal wherever frequently changing measurement setups, serial measurements, or large-area reference grids are required.

Product features

6 mm diameter for high visibility

Larger than 3mm markers, making them ideal for larger objects, complex contours, and measurement situations with wider scan distances.

Black/white contrast surface

Ensures clear, stable detection with optical algorithms of all common structured light and striped light scanners.

Magnetic adhesion

Reusable, precisely positionable and quick to remove.
Suitable for workpieces, fixtures, machine housings, body parts and all metallic surfaces.

Optimized for optical 3D measurement technology

Designed for

• Structured light scanner

• Striped light scanner

• Optical recording systems

• Visual marker tracking systems
  who need geometric reference points.

Quantity supplied: 500 pieces

Ideal for large-area measurement grids, extensive projects or regular scanning processes.

Application areas

1. Large-area optical surveying

Perfect for large components, technical assemblies, vehicle parts or large metallic structures.

2. Application at increased scan distances

The larger marking area enables stable detection even from a greater distance.

3. Serial measurements and testing processes

Ideal for repeatable measurement tasks in quality assurance, production testing and laboratory environments.

4. Object registration for complex geometries

A good choice when components are strongly curved, angular or unevenly shaped and clear reference points are needed.

5. Measurement technology in mechanical and plant engineering

Can be used on fixtures, machine frames, housings or large technical components.

Advantages of 6 mm black/white magnetic dots

Excellent detection rate

Large marking area + strong contrast = stable optical identification through almost all structured light systems.

High reusability

Magnetic attachment allows for frequent use without damaging surfaces.

Perfect for large objects

6 mm is the ideal size for measuring tasks where smaller markers would not be sufficiently visible.

Efficient handling

Quick to install, quick to remove, repositionable at any time.

Technical data

FAQ – Frequently Asked Questions

When are 6mm markers more useful than 3mm markers?

This applies when the components are larger, the scanner is positioned further away, or a larger visual recognition area is required.

Are the points detected by all structured light scanners?

Yes, optical 3D scanners with pattern recognition or marker tracking reliably identify the points.

Do the markers also adhere to painted metal?

Yes, as long as the surface is metallic, magnetic adhesion works without any problems.

Are the markers reusable?

Yes, they can be reused almost indefinitely.
