1 Create calibration pattern {#tutorial_camera_calibration_pattern}
2 =========================================
4 The goal of this tutorial is to learn how to create calibration pattern.
6 You can find a chessboard pattern in https://github.com/opencv/opencv/blob/3.4/doc/pattern.png
8 You can find a circleboard pattern in https://github.com/opencv/opencv/blob/3.4/doc/acircles_pattern.png
10 Create your own pattern
13 Now, if you want to create your own pattern, you will need python to use https://github.com/opencv/opencv/blob/3.4/doc/pattern_tools/gen_pattern.py
17 create a checkerboard pattern in file chessboard.svg with 9 rows, 6 columns and a square size of 20mm:
19 python gen_pattern.py -o chessboard.svg --rows 9 --columns 6 --type checkerboard --square_size 20
21 create a circle board pattern in file circleboard.svg with 7 rows, 5 columns and a radius of 15mm:
23 python gen_pattern.py -o circleboard.svg --rows 7 --columns 5 --type circles --square_size 15
25 create a circle board pattern in file acircleboard.svg with 7 rows, 5 columns and a square size of 10mm and less spacing between circle:
27 python gen_pattern.py -o acircleboard.svg --rows 7 --columns 5 --type acircles --square_size 10 --radius_rate 2
29 If you want to change unit use -u option (mm inches, px, m)
31 If you want to change page size use -w and -h options
