HI, after running the find_transform.launch file, only mono8 window is opening. I have not created the setup as of now but I want to know if the polygon window and point cloud window pops up when there is no marker at first.

It can be several things:

  1. the Arucos are not in ascending order from left to right
  2. The arucos are too small, try to print the arucos used in the paper, the number 26 annd 582 from the original dictionary Hope it helped :)

Hi @Z-Jeff, here’s the PDF of the markers. You can create your own using: https://chev.me/arucogen/
