Custom Products

Below you find a selection of custom calibration products which we have designed and manufactured in cooperation with some of our customers. These targets were made to fulfill special requirements pertaining to FOV, illumination wavelength, or mounting.

Should you be interested in one of these options, please request a quote or contact us and we can discuss your application and recommend the best solution.

Custom patterns

The largest group of custom products are specific patterns and sizes that we do not offer in our standard product portfolio. Examples of these are:

  • ChAruCo targets with different dictionaries and/or marker ids, enabling multiple boards to be detected simultanously in the same scene.
  • Circle/checkerboard targets with unique finder patterns, enabling partial observation and stereocalibration.
  • Deltille grid patterns and other less common targets.
  • Single AruCo marker plates for VR and robot calibration purposes.
  • MacBeth color calibration targets.
  • Proprietary customer designed patterns. We will never share these designs of course and can sign an NDA is requested.

For these custom designs, pricing depends mainly on the size of the desired board, and whether camera-ready vector graphics (true to scale, pure vector PDF/SVG with page size equal to board size, text converted to paths) are provided. We gladly assist in preparing or redrawing customer designs for a fee, and always provide a final PDF proof for the customer to verify before production.

Large FOV targets

Cameras should always be calibrated with the calibration target at the application’s working distance and also cover a rather large portion of the FOV in each single view. For large FOVs, we can manufacture targets up to 2500x1500mm in size. These need to be mounted into very rigid and flat frame structures. We can design and manufacture these structures for you or just deliver the plate insert. 

Pricing depends on size and complexity.

Infrared (thermal camera) calibration target

For thermal cameras, our standard targets are not ideal because the aluminium substrate has high thermal conductivity and the print does not give good contrast. For these purposes, we can provide a target printed onto a substrate with low thermal conductivity and high thermal capacity, ideal for storing and emitting thermal radiation contrast. The substrate also exhibits highly Lambertian reflectance properties across a wide range of the visible and IR spectrum and can also be useful for active 3D/range sensor calibration. This material is however not as durable as our standard product range and is not water resistant.

Pricing depends on size.

Mounting options

On these targets, the customers were interested in mounting the targets on conventional photographic tripods. We can offer bonding anodized mounting adapters to the plates facilitating this task. For smaller targets, the mounting plate can be glued, while for larger targets (over 600mm), we also use screws going through pre-routed holes in the targets.

 Pricing: from 100€ pr. plate.
