A web version ([https://www.ninox360.com/calibration-targets link]) of the desktop has been created and hosted by [https://www.ninox360.com Ninox 360]. It has almost all the features of the desktop application but runs in your browser.

BoofCV provides an application for generating your own custom calibration target. It allows you to specify which pattern you wish to use, the paper, and other specifications. A command line interface as well as a graphics interface are provided. The graphical interface gives you live preview as you adjust settings.

* [https://youtu.be/TGg-xgTyaU8?t=604 Video demonstration of GUI Application]
* [[Applications#Create_Calibration_Fiducials|Instructions for installing pre-built application]]
* Below are instructions for building it yourself from BoofCV's source code
<syntaxhighlight lang="bash">
cd boofcv
./gradlew applicationsJar
java -jar applications/applications.jar CreateCalibrationTarget
</syntaxhighlight>

The last line above will run the application with no arguments. This will print out up to date instructions. At the end of the instructions are examples for each target type on letter sized paper. If you wish to have a GUI when creating your calibration target add the --GUI flag. The GUI doesn't have all the options which the command line has.

<syntaxhighlight lang="bash">
java -jar applications/applications.jar CreateCalibrationTarget --GUI
</syntaxhighlight>

== Downloadable Targets ==

Instead of creating a custom target you can use one of the pregenerated targets for standard document sizes.

BoofCV is an open source library written from scratch for real-time computer vision. Its functionality covers a range of subjects, low-level image processing, camera calibration, feature detection/tracking, structure-from-motion, fiducial detection, and recognition. BoofCV has been released under an Apache 2.0 license for both academic and commercial use.

BoofCV is organized into several packages: ''image processing'', ''features'', ''geometric vision'', ''calibration'', ''recognition'',''visualize'', and ''IO''. ''Image processing'' contains commonly used image processing functions which operate directly on pixels. ''Features'' contains feature extraction algorithms for use in higher level operations. ''Calibration'' has routines for determining the camera's intrinsic and extrinsic parameters. ''Recognition'' is for recognition and tracking complex visual objects. ''Geometric vision'' is composed of routines for processing extracted image features using 2D and 3D geometry. ''Visualize'' has routines for rendering and displaying extracted features. ''IO'' has input and output routines for different data structures.
