OpenCV Calibration Targets

Custom OpenCV calibration targets

Test targets are very important when evaluating or calibrating an imaging system's performance or image quality. To make sure the accuracy of resolution, contrast, modulation transfer function (MTF), depth of field (DOF), and distortion;So one or more types of test targets may be necessary or helpful depending upon the type of system being constructed or what needs to be measured. Fortunately, an array of targets exists that suitable for specific systems including cameras, visual displays, or even a single, thin lens.

So to get a suitable calibration targets for the calibration work is the most important of all.Sometimes we need custom calibration targets to perfectly meet the special requirements..To make custom targets is what we can do for you,here we introduce our camera calibration with opencv.

To customize a OpenCV target is to consider some facts:

1, Substrate (Glass/Ceramic/Film/Carbon Fiber/Opal/Aluminum...)

2, Pattern Size

3, Coating Type :Black coating /Chrome/Blue Chrome/Brown Chrome/White Chrome...

4, Accuracy

5, Thickness

6, Front light source or back light source

7, Composite OpenCV Calibration Template available

8, Dig holes or cutting corners,make different shapes

9, The size can cover your camera's field of view (FOV) at the preferred working distance. The edges of the images is vital in determining lens distortion parameters.

Here are some samples of our customized chessboard targets including OpenCV targets:

About the details of making a custom OpenCV targets :

1, OpenCV target custom service procedure:

2, Ensure high accuracy: we have the advanced and complex production process to ensure the high accuracy,like black coating on quartz glass or float glass, chrome on ceramic or opal substrate...

3, Ensure the coating thickness 100~120nm:

4, Provide matchable backlight for glass targets:
