Tutorial
GUI
You can switch ArUco, ArUcoGrid, Chessboard and ChArUco mode at the GUI tab, then you can select dictionary from the GUI menu and modify board shape, marker size, border width... etc. at the GUI entry, finally click the preview or save button to show the marker image on the GUI window or save it to file.
Command-Line
Print help
Print predefined dictionary list
Save chessboard
Save ArUco
Save ArUco Grid
Save ChArUco
Useful Options:
Divde output to chunks
If you are using consumer level printer, you will suffer from not able printing too large marker, so just set chunks shape at the GUI subSize entry before saving the marker to files, it will divide output marker to chunks. If you are using command-line interface, just add --sub_size_x x --sub_size_y y as parameters.
Page border
If you are printing the image directly, you will need add page border to protect the marker, so just set page border at the GUI pageBorder entry before saving the marker to files. If you are using command-line interface, just add --page_border_x x --page_border_y y as parameters.
Generate aruco data:
Although there is a built-in aruco dictionary data, but if you want to update the dictionary(If aruco update predefined dictionary list), just install opencv-python and opencv-contrib-python, and than run

In Aspect
OpenCV is a local cross platform C++ Library for laptop imaginative and prescient, machine learning, and image processing. It is increasingly more being adopted in Python for enchancment. OpenCV has C++/C, Python, and Java interfaces with assist for House home windows, Linux, Mac, iOS, and Android. Builders using OpenCV assemble functions to course of seen data; this might embrace reside streaming data from a device like a camera, comparable to footage or videos. OpenCV provides in depth libraries with over 500 options
This book demonstrates strategies to develop a set of intermediate to superior duties using OpenCV and Python, comparatively than educating the core concepts of OpenCV in theoretical courses. Instead, the working duties developed on this book practice the reader how one can apply their theoretical info to topics harking back to image manipulation, augmented actuality, object monitoring, 3D scene reconstruction, statistical learning, and object categorization.
By the highest of this book, readers will in all probability be OpenCV specialists whose newly gained experience lets them develop their very personal superior laptop imaginative and prescient functions.
