Can you make the image you used to train the Haar available?

Thanks!

I'm running falkor_ardrone package on AR.Drone 2.0. As I see, this
code can control AR.Drone to follow moving targets which its path is
straight forward. So if the target move to left or right side or
rotate, the Drone can't follow it and move relative to its path. Is it
right? If yes, what should I do to append this ability to your code?
Do you have any reference or some pointers that can help me? I
couldn't find any reference that explain your algorithm.
Hope you can help me.

Hi,
When I launch the track.launch file I have a problem with the camera calibration file and it can not see the window with the front camera video. I am able to send commands from my PS3 controller and I can see the window with the battery level. Has somebody any idea how to solve the problem with the camera calibration file. The output of the tracker.launch is given below.

[ERROR] [1354020767.039146310]: Unable to open camera calibration file [/home/aga/.ros/camera_info/ardrone_front.yaml]

[ERROR] [1354020767.039304102]: Unable to open camera calibration file [/home/aga/.ros/camera_info/ardrone_bottom.yaml]

Thanks!

Hi,
When I roslaunch falkor_ardrone track.launch I get the following error. Any idea? Thx.

Hi there,

first of all, nice work, I really enjoyed using this stack 👍 I got it all running after a few system dependent hacks (got no PS3 controller, had to change the buttons). Anyway, I printed the Falkor logo, as provided, on a sheet of paper, inverted, which means: black logo on white paper. If I am right, this shouldn't harm the LBP classifier right? It's based on edge detection and the image will most probably converted to BW anyway...

As soon as I launch the drone (2.0), set it to "tracking" mode...it does nothing really, just hovering. The CV window also indicates "Tracking". I pulled the master, by the way, and I am using ROS Groovy on Ubuntu 12.10 (and also 12.04).

The only error messages are:

[ERROR] [1367779163.189744376]: Unable to open camera calibration file [/home/flier/.ros/camera_info/ardrone_front.yaml]
[ERROR] [1367779163.189816043]: Unable to open camera calibration file [/home/flier/.ros/camera_info/ardrone_bottom.yaml]

but they seem to be harmless, according to issue #2.

So - does the logo really need to be white on black? (I can see the optical flow bars though in the CV window...) Thank you for your time ;)
