[PlayerStage-Gazebo] distances to objects From: carlos villegas - 2004-10-04 16:29 ```Can I get, from Gazebo, distances to objects assuming I have a pioneer with laser and a few scattered objects in front of the robot? Can sombody point me in a GENERAL direction? ```

[PlayerStage-Gazebo] distances to objects carlos villegas <cav@us...>
 Re: [PlayerStage-Gazebo] distances to objects From: Carlos Villegas - 2004-10-05 03:33 ```OK, I did a little reading in the Gazebo manual and there are a couple of things that I might be able to use. But first let me make a correction about my previous message (below): I seek to get a image depth map (distances to objects) given two cameras (using triangulation). Is that something that can be done in Gazebo or I need to look at different sensors to get the distances (i.e. a Laser)?

 [PlayerStage-Gazebo] Creating my own terrain From: Carlos Villegas - 2004-10-05 03:42 ```I'd like to experiment with creating my own terrain in Gazebo. I looked at the terrain.world file included in the 0.4 distribution and noticed: 0.0 0.0 0.0 terrain.png 30 1 0.2 0.7 0.0 1.0 grid.ppm 100.0 100.0 Is there an article that explains the relationship between the terrain.png and the grid.ppm. And how to create each one of those? Thanks. Carlos ```

 Re: [PlayerStage-Gazebo] distances to objects From: Luis J. - 2004-10-05 18:38 ```Yes, you can get the distance to a object using third party vision librar= ies. You only need to center the object in the two cameras (by trying to reduc= e=20 the correlation of the center of the images for example). Then you use=20 triangulation. There are a lot of documentation related to it. Sorry for my poor english. :) Luis J.

 Re: [PlayerStage-Gazebo] Creating my own terrain From: Nate Koenig - 2004-10-08 19:17 ```Hi Carlos, The grid.ppm is just a texture image.The terrain.png is the grayscale images that specifies the shape of the landscape. Each pixel is interpreted as a height value, where white pixels are at the maximum height and black at the minimum. -nate On Mon, 04 Oct 2004 20:42:46 -0700, Carlos Villegas wrote: > I'd like to experiment with creating my own terrain in Gazebo. > > I looked at the terrain.world file included in the 0.4 distribution and > noticed: > > > 0.0 0.0 0.0 > terrain.png > 30 > 1 > 0.2 0.7 0.0 1.0 > grid.ppm > 100.0 100.0 > > Is there an article that explains the relationship between the terrain.png and the grid.ppm.

 Re: [PlayerStage-Gazebo] first time on CVS From: Reed Hedges - 2004-10-14 14:39 ```What versions of autoconf and automake do you have? Check: autoconf --version automake --version You might have other versions installed on your system. E.g. if "autoconf" is autoconf 2.13, you might have "autoconf-2.58", in which case you need to set some environment variables, and then change the bootstrap file to use the new versions. Do you have any custom-built auto* programs (e.g. in /usr/local)? In general, it's best to upgrade to the most recent versions that you can, at least automake 1.7 and autoconf 2.58.

It looks like your regular "autoconf" program is 2.59, and your "automake" is 1.8, which should work well. Renaming configure.in (old style) to configure.ac (new style) might help. When I need to use a differently named auto* binary to use the right version, what I've had success with in the past is to add the following to my .bashrc, or some file which I import manually into the shell. (e.g. name the file new_autotools, and then run ". ./new_autotools") -- export AUTOCONF=autoconf-2.59 export AUTOMAKE=automake-1.9 export ACLOCAL=aclocal-1.9 export AUTOHEADER=autoheader-2.59 export AUTOM4TE=autom4te-2.59 export AUTOSCAN=autoscan-2.59 export AUTOUPDATE=autoupdate-2.59 alias automake=\$AUTOMAKE alias autoconf=\$AUTOCONF alias autoreconf=autoreconf-2.59 alias aclocal=\$ACLOCAL alias autom4te=\$AUTOM4TE alias autoheader=\$AUTOHEADER alias autoscan=\$AUTOSCAN alias autoupdate=\$AUTOUPDATE ```
