Technical Specifications & Product Selection

 

Q: Which pattern type is optimal for my computer vision application?

A: Your optimal choice depends primarily on your software pipeline.

  • Checkerboards: The industry standard, widely supported across OpenCV, MATLAB’s Computer Vision Toolbox, and most photogrammetry packages.

  • ChArUco: Highly recommended for OpenCV users, offering robust detection even under partial occlusion.

  • Halcon: Specially designed for seamless integration with MVTec’s Halcon software. For an in-depth comparison, please review our [knowledge base articles].

 

Q: How do I determine the correct target size for my camera system? 

A: For optimal calibration, the target should fill most of your camera's Field of View (FOV) at your desired working distance. Capturing calibration data at the periphery of your images is critical for accurately modeling lens distortion. If your lens maintains sufficient focus at closer distances, a slightly smaller target may be used as a compromise.

 

Q: Should I select a fine or coarse pattern resolution? 

A: This depends on your camera’s sensor resolution and your lighting environment. Coarse patterns are designed for lower-resolution sensors (below 3 MP). However, if you have robust rigid mounting, controlled lighting, and higher resolution sensors, fine patterns will provide a higher density of feature points for superior calibration accuracy.

 

Q: What is the dimensional accuracy of the target features?

A: For our standard aluminum composite targets, the dimensional tolerance for feature point distances is 0.3 mm + 0.2 mm/m. For high-precision metrology applications, we offer targets manufactured using advanced lithography processes on thermally stable substrates. See this article for more information.

 

Q: Do you certificates or metrology report?

A: Yes, we can offer two levels of certification/metrology:

  • Calib.io Certification. We perform several distance and flatness measurements and certify that our manufacturing and product specifications are being met.
  • Measurement Report: The absolute 3D position of each saddle point or circle is measured and provided in a measurement report and as a digital file. For targets up to 400mm, a calibrated optical coordinate measurement machine (OMM) is used in an ISO-17025 accredited measurement laboratory. For larger targets, we use a photogrammetry measurement setup. Using actual 3D (x,y,z) positions of the feature points can significantly improve calibration results.

 

Customization & Manufacturing Capabilities

 

Q: Can you manufacture custom calibration targets to our exact specifications? 

A: Absolutely. We manufacture a wide array of custom targets tailored to specific FOVs, materials, and pattern types. Pricing and lead times for custom targets depend on the complexity and manufacturing process. Please submit a custom quote request with your engineering requirements.

 

Q: What are the maximum plate dimensions you can produce?

A: We utilize various manufacturing processes and substrate materials to accommodate large-scale calibration setups. We can manufacture calibration targets with dimensions up to 2000 x 1500 mm.

 

Q: What materials (substrates) do you use for your targets?

A: We offer a range of substrates depending on your need for rigidity, weight, thermal stability, and mounting method. Our standard is a durable, lightweight aluminum composite. For highly demanding thermal or optical requirements, we also offer glass and other specialized materials.

 

Q: Can we brand the targets with our company logo, serial numbers, or custom text?

A: Yes. We frequently OEM calibration targets for hardware manufacturers who bundle them with their 3D scanners, cameras, or optical products. We can include company logos, part numbers, and serializations. Contact sales@calib.io to discuss branding options.

 

Purchasing, Logistics & Procurement

 

Q: Do you ship internationally?

A: Yes, we ship globally. We use expedited international couriers, and transit typically takes 2 business days to most major global destinations. For full details on incoterms and customs, see our shipping policy page.

 

Q: What are your standard lead times?

A: Our standard manufacturing lead times are:

  • Stock items: Generally ship within 2 business days.

  • Backordered/Custom items: Typically require 14 to 21 days to accommodate data preparation, production queuing, and strict quality assurance protocols.

 

Q: Do you accept Purchase Orders (POs) or offer Net 30 payment terms?

A: Yes, we support standard B2B procurement processes. We accept formal Purchase Orders from corporate and academic institutions. Please contact our sales team to discuss payment terms.

 

Q: Do you offer volume pricing or academic discounts?

A: Yes. We offer tiered pricing for high-volume OEM integrations and discounts for academic or research institutions. Please mention your academic affiliation or volume requirements when using our quote request form.

 

Q: What is your return and QA policy?

A: Because calibration targets are precision measurement tools and often custom-manufactured on demand, we do not accept standard returns. However, every target undergoes rigorous quality inspection prior to dispatch. If a product is damaged in transit or fails to meet our stringent quality standards, please contact info@calib.io immediately so we can resolve the issue.
