Detailed description
I followed tutorial_camera_calibration_pattern to generate circle pattern:
python gen_pattern.py -o circleboard.svg --rows 7 --columns 5 --type circles --square_size 15and then i got error:
Traceback (most recent call last):
File "/home/kb/gen_pattern.py", line 217, in <module>
main()
File "/home/kb/gen_pattern.py", line 198, in main
if len(args.markers) % 2 == 1:
TypeError: object of type 'NoneType' has no len()It seems that -m is ONLY for radon checkerboard, but i cannot generate the other types of pattern without this parameter.
