Hi all,

I'm trying to visualize a PointCloud with pcl library in ROS fuerte (ubuntu 12.04). I'm including the pcl 1.7 library and the pcl_ros library.

I need to convert the point cloud from pcl::PointCloud<pcl::pointxyzrgb> to sensor_msgs::PointCloud2 in order to publish on topic the point cloud. But I think that in the new version of pcl library(1.7) the function pcl::toROSMsg() is not able to convert the point cloud to sensor_msgs::PointCloud2.

Any suggestions?

I also found a unstable version of pcl 1.7 library integrated in ROS: pcl17. Which is the right version of pcl I should use?

thank you in advance

Hi,

I'm using the ROS package ueye_cam (fuerte branch) and I would like to know how update the camera_info.

I do the calibration with camera_calibration ROS package, I convert the calibration info in .yaml file and I put these files in /home/../.ros/camera_info.

If I run

roslaunch ueye_cam master_slaves_rgb8.launch and I do rostopic echo /master/camera_info, I don't see the new value.

How can I update these values?

Thank you

Hi. I'm using ueye cameras, with frame rate: 15 fps (verified with rotopic hz) The resolution of the camera is 640x480, and they are synchronized via hardware.

If I run stereo_view with parameters approximate_sync to true and queue_size to high value, it doesn't work. The three windows are grey, without images.

Any suggestion?

thank you.

I solve the problem. It was a problem of the id of the cameras. I used the master_slaves_rgb8.launch and I modified the id name.

Hello, the topic is quite the same.

I have 2 cameras (UI-1241-LE-C-HQ) and I want to use both of them for sterevision. I'm trying to use the ROS package ueye_cam (fuerte branch).

When I run:

roslauch ueye_cam master_slaves_rgb8.launch

I get this error:

any suggestion? maybe @anqixu can help me.

thank you!

The package ueye_came-fuerte compiles and runs. The hydro version still has a problem. I can confirm that under the path [catkin_ws]/devel/lib there are the files libueye_cam_nodelet.so libueye_wrapper.so

Hi anqixu. I'm using ROS hydro, compiling the package with catkin_make, but I still have the same problem: [ERROR] [1389397299.178431342]: Failed to load nodelet [/ueye_cam_nodelet] of type [ueye_cam/ueye_cam_nodelet]: Could not find library corresponding to plugin ueye_cam/ueye_cam_nodelet. Make sure the plugin description XML file has the correct name of the library and that the library actually exists. ------ The library exist and it is in the right path. How can I solve this problem?
