Hi , i'm using rviz to visualize pointcloud from xtion through openni2. Could i have some help with configuration of octomap launch file to build map and visualize it in rviz . Thanks a lot.

Hi, I'm a student and i am trying to use an Asus Xtion through ROS ,on an Ubuntu14.04 laptop . My version of ROS is Indigo. I would be very gratefull if someone could explain me the method of installation. Precisely i'm interested to catch data from openNI and visualize to RViz. Thank you.

 
void callback(const QuaternionStampedConstPtr& quaternionS, const PointCloudConstPtr& pointcloud)
{
    scan_in = pointcloud;
    angle_in = quaternionS;

to_apply = TransformConstPtr(tf::Transform(angle_in.quaternion));

pcl_ros::transformPointCloud(pointcloud,scan_out,*to_apply);
 
}
 
PointCloud scan_in;
PointCloud * scan_out;
QuaternionStamped angle_in;
TransformConstPtr to_apply;

This is my situation and the pcl_ros::transformPointCloud(pointcloud,scan_out,*to_apply); function give me invalid argument error. How can i solve it??

Hi, i had a lms151 laser mounted on a rover. It's attached to a gimbal that i am able to rotate as i wish. Now i would ask for a method to accumulate the various laser scan and represent them in a fixed frame. I don't know how to rotate the laserScan according to the roll angle of the gimbal. Thanks.

Hi, i had a library compiled with cMake , and a .cpp executable that use this library. The building and running is made without the use of catkin or ros architecture. I would like to import this project in a ros package in order to use it to take data and publish them through a node.

Hi everyone!! My problem is this: i have a library "libRover.a" obtained compiling some .h and .cpp files with : cmake . make

Now i want in some way, create a ros package that use this library and allows me to use the function ,contained in the library, in a ros node to pubblish something .How is possible do this ??

Hello everyone, as the title say, i'm trying to combine depth image taken by xtion pro (NO LIVE) with rgb image taken by a webcam. Is there any to do it ???How?? Thank you so much.

It's the topic depth registered /image_rect that i need to feed fovis node, but my camera xtion pro NO LIVE i can't take rgb image but only depth image. How can i make visual odometry so ?

Hi, I run openni2.launch along my xtion but in rviz some topics show me black image when i choose camera . Instead i'm able to take pointcloud.

Hi, I'm looking for a ros package that allow me to make 3d map based only on image of my sensor ,that are depthimages and not rgbd ones, and not based on movement message from external sensor (VISUAL ODOMETRY). Thanks

(N.B. I'm also trying to calibrate my camera)

I had a question : Does fovis requires RGB image?? Because the xtion i had is unable. In this case , what kind of ros package i have to use to make visual odometry ?? THANKS

Hi, when i send the command catkin_make , appears at the end an error about CeresMake file . What's that?? Thank you.

I will try !

This is the code of launch files link text

I want to use fovis_ros with my xtion to build lately a 3d map using octomap , but when i start the launch file of openni2 and mono_deth_odometer of fovis package i have the following errors:

1)The camera say me that the image taken is uncalibrated. 2)Fovis_ros receive image and info from the respective topic , but the "synchronized tuples" are 0. 3)I cannot visualize in anyway the result from fovis_ros topic (features,pose,odoemtry).

Some news ???
