High-precision custom calibration targets for machine & computer vision applications
What Are Calibration Targets?
Calibration targets are precise, durable signboards designed explicitly for calibrating imaging systems used in machine and computer vision applications. Our custom calibration targets are made from two types of materials: ACM and Polyurethane. Both materials are lightweight, ultra-flat, rigid, and highly durable, making them suitable for indoor and outdoor use. These targets improve measurement accuracy by a factor of 10, making them indispensable in achieving precise results. Our calibration targets are trusted by technology companies and research institutions from around the world, highlighting their international demand and reliability in various industries.
ACM consists of two metal panels sandwiching a black polyurethane core and is available with an ultra-matte finish of 3mm or 6mm thickness. In contrast, Polyurethane is a solid compressed foam board featuring a natural matte surface, available in 3mm, 6mm, and 12mm thicknesses. The natural matte finish of Polyurethane is especially beneficial in environments with high lighting or when vision systems are exposed to various light sources, as it enhances detectability in machine vision applications. Additionally, high-volume geometric calibration of cameras can be achieved with a single image calibration solution, streamlining the process for users.
We provide various finishing options for our calibration targets, including:
-
Rounded corners (for easier handling of larger targets)
-
Special cuts (custom shapes)
-
Ultra Matte Finish (Near-Lambertian Surface)
-
Single or double-sided printing

Near-Lambertian Surface on ACM
(Ultra-Matte Finish · Available on ACM Only)
All calibration targets are printed using an ultra-matte finish by default, designed to minimize glare and reduce unwanted reflections. When applied to ACM (Aluminum Composite Material), the full-coverage application of UV-cured white ink further creates near-Lambertian reflectance, meaning light is diffused evenly across the surface rather than reflected in a directional pattern.
This consistent reflectance helps reduce intensity variation caused by viewing angle or uneven lighting, improving detection reliability when working with cameras, sensors, or measurement systems. Near-Lambertian surfaces are especially beneficial in real-world environments where lighting cannot be tightly controlled or when calibrating active or IR-based sensors.
The UV-ink surface on ACM is durable, scratch-resistant, and suitable for both indoor and outdoor calibration environments.

Frequently asked Questions
What are some Helpful Ordering Tips for uploading my own design?
These tips will help you during checkout and ensure your targets deliver optimal calibration results!
-
Always submit full-scale 1:1 files and adjust the product dimensions to match your file size. If needed, use decimal values to avoid unwanted scaling.
-
Upload your artwork in vector PDF or AI file format using CMYK color mode for the best print results.
-
During proofing, double-check that your file size matches the product size, ensuring they are both at a 1:1 scale. If they are not, you can either remove the files and reupload the corrected versions or update the product dimensions to match the file size (refer back to step one).
-
FoamCorePrint is not responsible for incorrect patterns or finished product sizes due to the improper scaling of customer-submitted artwork.
-
Submit your files for review. We encourage first-time customers to contact our customer support team to review all print files before placing orders via live chat or email.
Do custom calibration targets cost more than standard targets?
Unlike standard targets, custom calibration targets can do much, including modifying the target's shape. Because of additional features and finish options, the cost of custom calibration targets is typically higher than that of ready-made or standard targets. Fluorescent slides and disks also calibrate fluorescence imaging systems, offering specialized solutions for unique applications. Get a price instantly for your custom target, and use our "price calculator" tool to customize and select your target's thickness, size, features, and finish options.
Are your calibration targets waterproof?
Our targets are made from aluminum composite material, which is weather-resistant, rust, rot, and waterproof.
What size target board is best suitable for me?
A calibration target must occupy most of your camera's field of view (FOV) at the preferred working distance. Regardless, most software packages require visibility of the entire calibration target in all images/photos. So be sure your pattern and board fill your system's whole FOV. Before purchase, use this tool to calculate your field of view correctly!
What is camera calibration for cameras?
Camera calibration (or camera resectioning) is a 3D computer vision imaging process involving analyzing images of a rigid calibration target moved through a stereo camera pair's FOV (field of view). This procedure determines your camera's intrinsic and extrinsic parameters while triangulating the cameras' positions, and when calibrated, it will accurately correct your lens distortion. Use our free pattern generator software online to help you design the perfect calibration targets for calibrating your cameras that remove measurement bias. If you need help along the way, ask. We've got the expert insight to get you in the right direction in calibrating your system and adequately defining your 3D coordinate system space in no time!
What is camera calibration in computer vision?
Camera calibration is the process of determining a mathematical model for an optical system, in particular, a camera lens. This information can then correct distortions and other aberrations introduced by the optics. Camera calibration is essential because it helps reduce errors when using the camera's imaging system. Camera calibration is done with special equipment that projects patterns onto surfaces or into space and measures how these are distorted as they pass through the imaging system. Photographers often use ColorChecker targets for accurate color results in photography and filmmaking, ensuring consistency and precision in their work. The distortion data collected this way provides data needed to calibrate lenses.
What is a calibration matrix?
A calibration matrix is a table of values calibrating an instrument's response. This can be done by measuring the response from different known concentrations of analytes and creating a linear relationship between the measured concentration and its corresponding signal intensity. Using these data points, a camera calibration curve can then be developed.
