ar_drone_moveit troubles

[axelfar]

I have find how execute the path.

1. Put Tum in autopilot
2. Controller -> press p and s
3. In octomap when you have a good map plan and execute the path

I just have a problem with the distance conversion.

And I don't know how to change the octomap generation :(

I am experiencing the same thing. The drone does not move. Could it be because of using tum_ardrone in joystick mode earlier. There seems to be some issue changing to autopilot. I tried to switch to autopilot after initially using joystick mode but drone does not even respond to takeoff command in autopilot mode.

@kungfrank
I have a problem with conversion.cpp
I don't have the same result for a same drone position. And my result in RVIZ is small and compressed like this:

And I want this result :

In the last photo I have fix manually the different parameters. But when I generate a path my program didn't have a good estimation of distances.
In conversion.cpp you do a matrix rotation of 45°? why not 90°?

I got a different problem when running rosrun lsd_slam_viewer viewer
$ rosrun lsd_slam_core live_slam image:=/ardrone/front/image_rect camera_info:=/ardrone/front/camera_info

this is a description of the problem what I have met[https://answers.ros.org/question/296036/couldnt-see-the-image-and-depth-map-when-running-lsd-slam/] @axelfar @boonflies @kungfrank thank you in advance

[axelfar]

Hi,
Have you check if you see image_rect and camera_info when you do rostopic list?
And if all seems good when you spec with rostopic echo ?
I did not have those errors :/

[TengFeiHan0]

@axelfar @kungfrank I followed these steps you listed as before, all packages were compiled smoothly. However, when typing rosrun lsd_slam_core live_slam image:=/ardrone/front/image_rect camera_info:=/ardrone/front/camera_info segmentation fault(core dumped) was found in the terminal.__
here is my rqt_graph. I promise I typed your instructions step by step. So I don't know how to fix this problem.

[kungfrank]

@TengFeiHan0 Please have a look at issue#1
#1

[TengFeiHan0]

@kungfrank thank you for your reply. the question is when typing rosrun lsd_slam_core live_slam image:=/ardrone/front/image_rect camera_info:=/ardrone/front/camera_info, I couldn't see anything except segementation fault

[kungfrank]

Maybe this one #3 (comment)

@kungfrank

after a calibration of my drone, I tried to start mapping thread as displayed in the image, it said that the tracking has been lost. I retried several times. Unfortunately, the output is always the same with what I have said before. Do you know the reason?

[TengFeiHan0]

Just what I have displayed as before, tracking thread is vulnerable to lose. I have tried several times and can't get a set of good key points. whether it relates to my calibration file? @kungfrank @jim1993 @kaiwu013

[kungfrank]

@TengFeiHan0
Yes, LSD_SLAM lose track problem is cause by calibration file.
As far as I remember, you can find this problem in one of LSD_SLAM repo's issue.
