Hi, I know this is an old post. But i have your same problem. Did you solve it?? I have been trying to solve by myself for a week with no dice!!! Could you help me??? Thanks

Hi,i have the same problem of yours and the same kinect model (1473). Did you find a way to get kinect aux working??? Thanks

Hi, i got the same error with kinect streaming point-cloud. Normal cloud size always zero....!!! The code seems right and i don't know how to solve that error. Could you give me some hints if you solved the problem?? Thanks.

Hi, I use ros hydro on Ubuntu 12.04.2 64bit When i roslaunch openni_launch openni_launch my kinect is detected as follow

INFO 1394365533.465161719: Number devices connected: 1 INFO [1394365533.465274119: 1. device on bus 002:13 is a SensorV2 (2ae) from PrimeSense (45e) with serial id '0000000000000000' INFO 1394365533.466437879: Searching for device with index = 1 INFO 1394365533.516393959: Opened 'SensorV2' on bus 2:13 with serial number '0000000000000000' INFO 1394365534.273550599 : rgb_frame_id = '/camera_rgb_optical_frame' INFO 1394365534.274270159: depth_frame_id = '/camera_depth_optical_frame'

When i try roslaunch freenect_launch freenect-registered-xyzrgb.launch i get:

Again using roslaunch openni2_launch openni2.launch:

Maybe i'm forgetting something but i don't know what exactly.

This is my lsusb:

Could you help me?

Thanks.

Arduino Mega 2560 too.Still same problem. I switched to an USB-ISS converter and wrote a node to talk to my sensors by I2C, using write,read unix function. If someone is able to solve it,Please let us know.Thanks.

Hi,I installed rosserial hydro for arduino and ros_lib as written in the wiki. when I try ros hello world example found in ros_lib it compiles and works fine but when i try a ros_lib example with a subscriber, whatever topic name is, i get (from pubsub ros example):

[INFO] [WallTime: 1380287883.995053] ROS Serial Python Node [INFO] [WallTime: 1380287884.001497] Connecting to /dev/ttyACM0 at 57600 baud [INFO] [WallTime: 1380287886.607383] Note: publish buffer size is 512 bytes [INFO] [WallTime: 1380287886.607882] Setup publisher on chatter [std_msgs/String] [ERROR] [WallTime: 1380287886.609524] Creation of subscriber failed: unpack requires a string argument of length 4.

So publisher is created but subscriber fails....! I use hydro on ubuntu 12.04 64bit.Is there a way to solve it?I'm stuck here...!Someone can help me? thank!

Thanks. If it can help...I switched to hydro and now registered depth works. bye

Hi, i have the same problem, but mine can't be solved as yours...i dont know why...!!!I tried ros hello world example and it works fine but when i try an example with a subscriber, whatever topic name is, i get : (from pubsub ros example) [INFO] [WallTime: 1380287883.995053] ROS Serial Python Node [INFO] [WallTime: 1380287884.001497] Connecting to /dev/ttyACM0 at 57600 baud [INFO] [WallTime: 1380287886.607383] Note: publish buffer size is 512 bytes [INFO] [WallTime: 1380287886.607882] Setup publisher on chatter [std_msgs/String] [ERROR] [WallTime: 1380287886.609524] Creation of subscriber failed: unpack requires a string argument of length 4 I use hydro on ubuntu 12.04 64bit.Is there a way to solve it?I'm stuck here...!Someone can help me? thank!

I use MacBook unibody late 2008 Ubuntu 12.04 partitioned. Is there a single command to remove ROS and OpenNI??But after reinstalling ROS and openni what should i do if i get the same issue related to registered-depth-image??If i followed again your steps above, could i end up in the same situation of today? Thanks

No dice. I read all posts but no solution found yet. It seems the only way is to reinstall the entire Ubuntu:... Obviously not acceptable..!! but If i did a fresh install , could i encounter the same issue? Someone might give me any advise?!i'm stuck and I can't go on with my project....! thanks

Thank for reply. If i type rmmod gspca_kinect i get "Module gspca_kinect does not exist in /proc/modules";However gspca_kinect blaklisted but again no device connetted...! here is what i did: sudo apt-remove openni_camera, openni_launch, libopenni-dev. Then followed your guide to install openni & avin2 kinect sensor. Then sudo apt-get install openni_camera, openni_launch.

Hi, i followed george steps but now when i roslaunch openni_launch openni_launch i get: [ INFO] [1379865586.935153519]: No devices connected.... waiting for devices to be connected ........ ........ Before openni could find my kinect...what i'm missing?? Please help me. thanks (Ubuntu 12.04 ROS fuerte) Here is my lsusb command: Bus 001 Device 025: ID 045e:02c2 Microsoft Corp. Bus 001 Device 026: ID 045e:02ad Microsoft Corp. Xbox NUI Audio Bus 001 Device 028: ID 045e:02ae Microsoft Corp. Xbox NUI Camera So kinect is found by pc!! Thanks.

Hi, sorry if i open an old post but i have the same problem. i've been trying for 4 months....it wont work!!Did someone share its own sd image?? Thanks

Hi, thanks for pointing out your site. it helps me a lot. I followed your steps for extrinsic parameters but i'm stuck at the optimization phase. camera_pose can detect the chessboard in both images, both bars become full green but no optimization starts...hence no extrinsic_bag file is generated. What i'm missing?? Could you help me? Thanks a lot.

Hi,

I don't know if it's a bug or i did something wrong......!!!

Someone could check it..??

Thanks Again.

Hi,

I use rviz on ROS fuerte and arduino by rosserial.

Arduino receives angles value from IMU and x,y position from encoders. Hence i use transform tf to publish pose of /odom frame wrt /base_frame.

In rviz i set TF to see the 2 reference frames but i obtain different values than the ones arduino publishes. In fact if i fix position x=y=z=1 and fill quaternion values with my IMU angles, rviz shows me different position x,y,z values varying in time and quaternion values x,y,z that are negative wrt real one.

But if I run "rostopic echo tf" i can see that arduino broadcasts the exact values.

Moreover if i fix position x=y=z=0 i obtain in rviz the exact values. But if i fix position x=y=z=2 i obtain in rviz x,y,z position values that are twice the one obtained fixing x=y=z=1.

Someone can help me??

Thanks.
