How to run these two packages on ros?

[haotiz]

Hi, I'm a student who is working on a class project for the autonomous landing. I'm not quite familiar with the ros, could you please help me with it by writing me a small tutorial on how to use these packages! Thank you so much for your time concern!

Hi @haotiz,

This package was developed and tested on ROS Indigo, Ubuntu 14.04. Said that:

1. Calibrate your camera and make sure the parameters are being published on the topic camera/camera_info (or do some remapping).
2. Compile both packages in your catkin workspace
3. Print your desired target - I recommend an 'H' pattern with the horizontal bar displaced forward or backward.
4. Aim your camera such that your target is the largest blob in the scene, then launch the uspart_landing/launch/learning.launch
   roslaunch uspart_landing learning.launch

Move the camera around and make sure the target is always being detected (There should be a bounding box around the target in the output image)

5. Save the parameters and make your own launch using as references the files uspart_landing/params/h_modified.yaml and uspart_landing/params/generic.launch

Good luck there!

Best,
Rômulo
