Problem setting fixed frame in Rviz.
I am already able to publish the data, in the sense that when i type the rostopic hz -> i get the topic that i am publishing. But have difficulty visualizing the data and moreover, i can't select anything under fixed frame and target frame.there is a global warning saying that is no tf data and that Fixed Frame does not exist. I now know i need to have to a launch file that converts static_transform_publisher from /world to /kinect_depth and set the fixed frame to /kinect_depth.
1)i am not sure where to add this file to?
2) there is a statement args = " 0 0 1.10 -1.57 0 -1.57 /world /kinect_rgb 10" what does the 10 stand for and what are the other values(such as 0, 1.1) for?
having those two questions answered, i got a few more to ask( i apologise if the qns are wrong)..
3) what should i type to launch the kinect_camera. is it roslaunch kinect_camera kinect_with_tf.launch? if so, it is wrong to type roscore only? 4) must u have always have a launch file? can u work without a launch file?
5)is better to use tf::transformbroadcaster or it is better to use just launch file?
Please pardon me for the qns.. i am newbie in ROS, point cloud. Any help would be much appreciated.. thanks...
for env | grep ROS i get
