Hi I am trying to use Voxelized Shape and Color Histograms (VOSCH) in order to recognize an object, I follow this link http://wiki.ros.org/vosch ,but when I run :

rosrun vosch example_vosch rospack find vosch/data/sample_cone_green.pcd

I got the Error that

Couldn't find executable named example_vosch below /opt/ros/fuerte/stacks/mapping/vosch

can anyone help me to fix it?

Thank's Adreno I think it's good. but I got problem in VOSCH installation.

Hi I am using the tabletop object detector to determine some object on point cloud database.
http://www.ros.org/wiki/tabletop_obje...

I was wondering if I would able to somehow also extract color information about the objects. I want to know that can I use color information or RGB image by tabletop library? If not ,does anybody know of a tool that does anything similar???

I am trying to get a 2d map. I use ubuntu 12.04, fuerte and kinect. I am following the slam_gmapping tutorial

MappingFromLoggedData.

My execution sequence is as follow:

1.rosmake gmapping

2.rosbag record -O mylaserdata /base_scan /tf

then I drive the robot around , and after that I Kill the rosbag instance

3.roscore

4.rosparam set use_sim_time true

5.rosrun gmapping slam_gmapping scan:=base_scan

6.rosbag play mylaserdata.bag

7.rosrun map_server map_saver

And then when I execute 7, I couldn't get map file. actually it always said "waiting for the map". Also I couldn't see my map on rviz

help me plz

I am using ros fuerte on ubuntu 12.04 and have a questions:

how can I extract or get the axis of a point in my slam by Rgbdslam?

I use Ubuntu 12.04 and ROS Fuerte. I want to install RGBD slam.I try above commends in my ros package path

> $svn co http://alufr-ros-pkg.googlecode.com/s...
$rosdep update

but while I type this command > rosdep install rgbdslam_freiburg I got these error

When I open rviz, I chosed pointcloud2 by click on add bottom but I don't know how and where should I set topic as

for it .

I just brought a kinect and wanted to the rgdbslam I download the Sensor Kinect and installed it. after that I issued "roslaunch openni_launch openni.launch" and I got the following error messages"

>[ WARN] [1391410256.310823768]: Camera calibration file /home/ghazaleh/.ros/camera_info/rgb_B00365209795052B.yaml not found. <

I have installed openni package by above commands:

> sudo apt-get install ros-fuerte-openni-camera sudo apt-get install ros-fuerte-openni-launch

the connection is ok because when I run

> freenect-glview

I can see the picture does anyone knows what's going on ?

I am new In ROS. I am working on a quadrotor, And I want to start image processing by ROS, in order to mapping,detecting faces, detecting objects and letters. I am looking for some tips and instruction to start it as a beginner.
