Hi

I am using ubuntu 11.04, electric and kinect with openni.

I want to build 3D indoor map.

So I read the rgbslam (http://www.ros.org/wiki/rgbdslam).

But I don't know how to use it.

How to create maps using rgbslam?

Or Do you know other way??

Hi

I am using ubuntu 11.04, electric and kinect with openni.

I only study tutorials (http://www.ros.org/wiki/ROS/Tutorials)

and openni_launch (http://www.ros.org/wiki/openni_launch).

I'm still new to ROS.

I want to build 3D indoor map.

But I don't know what to do.

How to create maps using ROS and Kinect?

Can you teach method, tutorial, material etc. ?

please~~

kinect 3D point has the world coordinate (x,y,z).

where is the the origin of the world coordinates(0,0,0)?

I am sorry~ but I don't find "add comment" in windows. How can I find it. I use ros in ubuntu now. And can you answer my former question? please

I also read the page (http://openkinect.org/wiki/Imaging_Information#Depth_Camera)

" The raw 11-bit disparity value to a depth value in centimeters is:

100/(-0.00307 * rawDisparity + 3.33). "

1. depth value = distance. Is it right?

2. So, how can I get the rawDisparity?

I know that each pixel in the depth image is supposed to relate to the distance

of that part of the scene, but no unit ( not [mm] ).

How do we translate from these value to a distance measurement in some kind of

useful units like [mm]?

Can you tell me the changable fomula?

And can you teach map-building materials or tutorials?

I want to 3D map. Just z=0 of x,y,z data. I want to changing data. Is there no way?

I want to build 3D indoor map.

First, I want to do (z=o) floor map building.

(From x,y,z depth data to z=0 data)

But I don't know what to do.

Thank you~

I am using ROS electric on Ubuntu 11.10..

I want to use kinect for SLAM. In this process I can't get the map generated

using rgbdslam package and I don't know how to obtain the rgb and depth data

generated by the sensor. Just look display ( roslaunch rgbdslam

kinect+rgbdslam.launch )Where is the map, the rgbd data stored and how can I

obtain it?

I am new to this thing.

somebody help me~~

To start RGBDSLAM launch " roslaunch rgbdslam kinect+rgbdslam.launch" I see the rgb and depth image. After, I don't know what to do. how to process the image
