2011-10-12 00:07:42 -0500	asked a question	Mirroring RGB image Hi, i'd like to know how image mirroring works. My launch file is this: `<launch> <include file="$(find openni_camera)/launch/openni_node.launch"/> <remap from="video" to="/camera/rgb/image_color"/> <node pkg="merge" name="faces_detection" type="detection" respawn="true" output="screen"/> <node pkg="dynamic_reconfigure" type="dynparam" name="ressetter" args="set /openni_camera point_cloud_resolution 0" /> <remap from="points" to="/camera/depth/points"/> <node pkg="merge" type="people_viewer" name="people_viewer" output="screen" respawn="true" /> </launch>` I have two viewer: the first show RGB video (it obtain images using rgb transporter), the second is a depth viewer that show points using PCL library. I don't know why RGB images are mirrored and depth no. How can i change this settings?

2011-10-10 23:40:50 -0500	commented answer	Get RGB pixel coordinate in depth cloud Running rosrun dynamic_reconfigure reconfigure_gui "depth_registration" parameter is ticked, is that what you mean?
2011-10-10 21:09:20 -0500	asked a question	Get RGB pixel coordinate in depth cloud Hi there! I'm using pcl point cloud to show depth information obtained with kinect. I'd like to identify rbg points (pixels) on the depth map (for example eye balls). How can i obtain real world coordinate (x,y,z) from the RGB pixel (u,v)? I've found this istructions: `cloud(right_eye.x,right_eye.y).x cloud(right_eye.x,right_eye.y).y cloud(right_eye.x,right_eye.y).z` where cloud is defined as: `pcl::PointCloud<pcl::PointXYZ> cloud` But the result is not correct, i mean rgb points are not fitted on the depth map.
