"""Markers map generator
Generate map file for aruco_map nodelet.
Usage:
genmap.py <length> <x> <y> <dist_x> <dist_y> [<first>] [<x0>] [<y0>] [--top-left | --bottom-left] [-o <filename>]
genmap.py (-h | --help)
Options:
<length> Marker side length
<x> Marker count along X axis
<y> Marker count along Y axis
<dist_x> Distance between markers along X axis
<dist_y> Distance between markers along Y axis
<first> First marker ID [default: 0]
<x0> X coordinate for the first marker [default: 0]
<y0> Y coordinate for the first marker [default: 0]
--top-left First marker is on top-left (default)
--bottom-left First marker is on bottom-left
-o <filename> Output map file name in the 'map' subdirectory of aruco_pose package
Example:
rosrun aruco_pose genmap.py 0.33 2 4 1 1 0 -o test_map.txt
