Hello again!
Thank you Rich for your answer.
However no luck, it seems i dont get any data from the cam.image.
Do you or anyone else have any other idea in order to get camera frames from
player in python?  (btw sorry for the bad subject name)

    client = playerc_client(None, 'localhost', 6665)
    cam = playerc_camera(client, 0)

    if client.read() == None:
        raise Exception(playerc_error_str())
    
    img = cv.CreateImageHeader((cam.width,cam.height), cv.IPL_DEPTH_8U, cam.bpp/8)  
    cv.SetData(img, cam.image, cam.image_count) 
    print img
    cv.ShowImage ('Camera', img) 

----- Outputs
>From the print img:
<iplimage(nChannels=3 width=640 height=480 widthStep=921600 )>

And then error at next line:   cv.ShowImage ('Camera', img) 
TypeError: IplImage argument 'image' has no data

[Playerstage-users] question about compatility

[Valentino <puntovale@gm...>]

I am an old member of Player 2.0.5 and Gazebo 0.7.0. I need to reuse my old
code but I would not change anything.  What is the latest version of Player
and GAZEBO I can use without having to change my code? if I wanted to use
the latest version of the Gazebo, it would be compatible with version 2.0.5
of player?

Thanks in advance,
Best regards

Re: [Playerstage-users] Player/Stage on Mac OS X 10.6 Snow Leopard in 64-bit

[Gonçalo Cabrita <goncabrita@gm...>]

Thanks for all the help,

I added

export
DYLD_LIBRARY_PATH=/System/Library/Frameworks/ApplicationServices.framework/Versions/A/Frameworks/ImageIO.framework/Versions/A/Resources:/swl/lib

to my .profile and now I can run stage from player as a plugin. I'm running
fink with player stage in 64-bit as described in my first post, only without
gearbox.

However I cannot run plugin drivers of my own. For example, I made a
Roomba500 plugin driver, when I compile it and try to run it I get the
following:

I even run otool after and everything seems to be in place. I also tried
adding the path to this dylib to DYLD_LIBRARY_PATH but it doesn't work. This
plugin driver has already been tested on linux and it is working. I've also
tried different approaches of installing player/stage on Mac OS X, most work
just fine, wether they are 32bit, 64bit, using fink, macports, but I always
have this problem with plugin drivers. I'm using Mac OS X libtool when
building player and stage, could the problem be related to libtool?

Re: [Playerstage-users] Playerstage-users Digest, Vol 46, Issue 31

[Rich Mattes <jpgr87@gm...>]

OpenCV and Player store their image data in similar array structures.  The
OpenCV Python interface documentation [1] has an example for PIL Image ->
OpenCV that looks like a good jumping off point.  I’ve been successful in
converting Player images to IplImages and back in C++, I don’t think it’s
terribly different in Python.  It looks like you need to do something like:

 

from playerc import *

import cv

client = playerc_client(None, ‘localhost’, 6665)

cam= playerc_camera(client,0)

 

cv_im = cv.CreateImageHeader((cam.width,cam.height), cv.IPL_DEPTH_8U,
cam.depth/8)

cv.SetData(cv_im, cam.image)

 

If you’re using color images, you might have to do a cvCvtColor(src, dest,
CV_RGB2BGR), as the IplImage* structure inexplicably stores image data in
BGR format.  I’m not a python expert, and I would be quite surprised if the
above code runs, but I think I’ve captured the gist of the conversion.

Re: [Playerstage-users] Using Player 3.0.1

[Rich Mattes <jpgr87@gm...>]

player.dox.in is a template that gets filled in by cmake during the build
process.  If you use the option -DBUILD_DOCUMENTATION=ON when you run cmake,
there should be a player.dox in the doc directory.

The documentation on the website is very out of date, but you can generate
new documentation from the source (search the mailing list, this came up a
little while ago).  Playerc++ hasn't changed too much between 2.1 and 3.0.
The hokuyo_aist driver uses the "ranger" interface instead of "laser".  You
might have to change your code or use "rangertolaser".

Hey everyone

I stand in a small problem, for previous projects have I used Player 2.1.3,
but for my Hokuyo laser, Player 3.0.1 provides a better driver. 
My problem is that the new player is soo confusing in its setup, make no
sense to me, and I have been unable to find the playerc++.h file and seems
no documentation is available. I is possible for someone to line up how to
setup and compile a program with the new Player? 

Ps. 
Is any change needed in my previous code for Player 2.1.3 to make it work
under Player 3.0.1?

Hi all,

:clap:

I got that error when I was running my code for about 5 minutes. the robot
could not moving well and lagged behind the original`s pose. when I saw the
terminal this error came up: :-((
playerc error   : queue overflow; discarding packets
playerc error   : queue overflow; discarding packets
playerc error   : queue overflow; discarding packets
playerc error   : queue overflow; discarding packets
playerc error   : queue overflow; discarding packets
playerc error   : queue overflow; discarding packets

I integrated the playernav with the laser scanning process so that the
playernav can show the scanning result of the laser.
i`m using gnomecanvas for the drawing part of the laser result.

it seemed that the error was due to so many item that I draw using the
gnomecanvas. if I reduced the number of particle for drawing part, the robot
could move very well according to the orginal robot moving.

is there a way in gnomecanvas to store a large value of the data? let say
save it in the array?
or anyone know how to solve the "playerc error   : queue overflow;
discarding packets" :-D


thanks a lot for ur help!!  =)

Warm regards,
Budi

[Playerstage-users] Help -- Gazebo 0.10. failed to compile ...

[JIA Pei <jp4work@gm...>]

Hi, all:

I successfully installed player-3.0.1, Stage-3.2.2-Source, Ogre3d 1.7.0 and
current Bullet SVN R2702.
However, I'm not able to compile gazebo . It looks it's an error from Bullet
.

So, can anybody give me some hints on why it is so?

BTW, my
OS: Ubuntu 9.10
GCC: gcc (Ubuntu 4.4.1-4ubuntu9) 4.4.1

The error is as follows:

Re: [Playerstage-users] player 3.0.1: couldn't synchronize with P2OS

[Paul Osmialowski <newchief@ki...>]

Hi,

Try to set ignore_checksum option to 1 in p2os driver configuration.
