How to transform the whole /tf frame?
Given I have an occupancy grid map which I would want to transform with a certain [tx,ty,theta] transformation. How do I do it? The tf tree is posted below and also the rviz which contains the grid map. My ultimate goal is that I would have two occupancy grid maps which I would have to apply a transformation to either one of them so that they can be overlapped -- Map Merging. I'm looking for the mechanism in ROS where I can transform the map, particularly the whole /tf frame so that even the robot's pose will be transformed into a new coordinate frame.
Hi Xegara, I am looking at your /tf frames in the first image, and I am wondering how you were able to link /camera_link to /map? What launch files did you use to connect octomap and rgbdslam? Are you able to share what code in the .launch file (or your method of connecting the two and projecting the map?) Thank you.
You can run the following commands: roscore roslaunch rgbdslam slow_computer.launch roslaunch rgbdslam octomap_server.launch roslaunch openni_launch openni.launch The rgbdslam node itself also creates the tf tree I uploaded in the first image.
