2014-01-28 17:28:56 -0600 marked best answer How to know which object roboearth is seeing

Hi!

I'm new with roboearth. I've already created some models in my computer and I have also succeded when trying to detect the object. The problem is: when I load different models and I put the detector to work, is there any way to know which object is being detected? I mean, is there a service/node/something that says "I've detected a box", "I've detected a can", etc. ?

Any help is welcome! Thanks!

Hi,

I'm trying to install RoboEarth on my Ubuntu 10.10 and I'm following the steps at the wiki page. Somewhere along the line, I have to use the command rosinstall, but it doesn't work. When I try sudo apt-get install python-rosinstall , I get the following error:

E: Unable to locate package python-rosinstall.

If I try the command sudo pip install -U rosinstall, I get the message:

sudo: pip:command not found.

What should I do?

I'm a beginner, so any help is welcome! Thanks!

EDIT: After michikarg's help, I was able to run rosinstall but I'm still having problems with the installation process. Some of the dependencies were not found, even some that are already installed such as libqt4-dev.

Here is the log message (by the way, I'm using ROS Electric):

Hi everyone!

I've been using ar_pose on ROS Fuerte for some time, but I want to update and start working with ROS Hydro. However, ar_pose doesn't work when using Groovy and Hydro.

Is there any update or any changes that should be made in order to have it working?

Thanks!

2013-06-07 00:17:31 -0600 marked best answer Can't get correct position of ARMarkers

Hi everyone!

I'm using ar_pose to identify some markers. It identifies the markers correctly (pattern 1, 2, etc.), but their positions are not very good. The distance is not being correctly assigned. I guess this is not ar_pose's problem.

See the image below:

image description

Could it be a depth_registration issue?

Also, I tried calibrating my camera (kinect) following these tutorials:

1) rgb calibration

2) IR calibration

If couldn't make myself clear, please, tell me, so that I can explain it better.

I would really appreciate if someone could help me!

Thanks!

2013-06-06 04:53:19 -0600 asked a question Pioneer3-AT Rviz/urdf model

Hi everyone!

I am running a SLAM simulation using a Pioneer3-AT and it would be usefull if I had the pioneer's model on Rviz. That is, is there a way or a place where I can get a model of the P3-AT running on Rviz (urdf?) ? My objective is to have the real pioneer working on real world and a "picture" of him running on Rviz (in the same position as my "\base_link").

I know there is p2os_urdf, but the model it gives is not exactly the one I want. Is there an easy way to edit this model into the one I want?

Thanks in advance!

Hi everyone!

I'm trying to get the image from my Fire-i400 1394 camera. In order to do that, I am using the following comands:

$ rosrun camera1394 camera1394_node

$ ROS_NAMESPACE=camera rosrun image_proc image_proc

$ rosrun image_view image_view image:=camera/image_rect_color

and this should give me the images, with color. But I'm getting the following message:

Color topic '/camera/image_color' requested, but raw image data from topic '/camera/image_raw' is grayscale

then, the images come up, but they are on grayscale.

Does anybody know why it is happening? What am I doing wrong?

Thanks in advance!
