2015-02-11 11:34:49 -0500 answered a question How do you calibrate the extrinsic parameters?

Hello,

I posted a similar question a while ago, and not having found a good solution, i coded one myself (unaware of ros industrial package). My solution needs a way to recover a frame through the camera, like ar_pose, plus a marker that is attached to the end effector (no need to know where, only that does not move during calibration). I checked it with Asus Xtion + ar_kinect the solution gives the camera to base frame transformation (plus the position of marker w.r.t. the robot link where the marker is attached, a data that is normally discarded)

see camera_robot_calibration

Since I did not find any out-of-the-box solution, i made one myself! https://github.com/gborghesan/camera_...

Dears, I would like to scale down the interactive markers arrows and circle of controlling orientation. I am using one of the python example (simple six dof). i could not find a simple way to do it. Cheers Gianni.

Dear all, I would like to set up a Kinect or another camera in a space where a robot (a kuka lwr) will operate. The camera will be fixed w.r.t. the robot base. There is some software that computes the homogeneous transformation for me? Also reference to solve this problem are happily accepted.

2013-10-28 00:51:38 -0500 asked a question rviz in groovy: .dae file are not longer displayed

I recently updated to groovy, and in the mesh files in rosie_description does not show up anymore. Peering in the urdf i saw that it points to .dae files. in the rosie description are present also .stl files, so i changed the urdf file, having the visualization back.

There is some way to get back working with .dae file? PS: Rviz does not give any error.
