2016-08-08 09:07:20 -0500 | asked a question | Trouble with visp_camera_calibration I've been trying to perform hand-eye calibration on my Baxter robot using the visp_camera_calibration package with this tutorial: http://wiki.ros.org/visp_camera_calib... I am using an ASUS Xtion, which is not a firewire camera, so I have changed the launch file as follows: <launch> <node pkg="rqt_console" name="rqt_console" type="rqt_console"/> <node pkg="openni_camera" type="openni_node" name="camera_node"/> <node pkg="image_view" type="image_view" name="my_image_raw_viewer" args="image:=/camera/rgb/image_raw"/> <arg name="calibration_path" default="calibration.ini"/> <group ns="visp_camera_calibration"> </group> </launch> I realised that openni publishes to camera/rgb/image_raw as opposed to just camera/image_raw so I ran it with $ roslaunch calib-live-firewire.launch camera/image_raw:=/camera/rgb/image_raw camera_prefix:=/camera/rgb $ roslaunch openni_launch openni.launch (new terminal) This opens the image viewer fine and I can see the Xtion feed, as well as opens the rqt view fine. The issue is that I can't get the image into the calibration window. I have opened ... (more) |

2016-07-07 06:28:08 -0500 | answered a question | Which RGB-D sensor is better with ROS packages? I've only used the Xtion Pro Live and it works pretty well. I've seen a lot of people using Kinect v2 cameras, so there will be a lot of support for these. They are also higher resolution than the Xtion Pro live and the v1 so will be a bit better. I personally wouldn't buy one of the original Kinects, but it's up to you as they are pretty cheap. If I was to buy one today I would buy a Kinect v2, because they have good resolution and a good community of support. |
2016-07-04 09:22:33 -0500 | asked a question | OpenNI camera calibration yaml file not found This is my first question, so forgive me for any formatting issues. I'm trying to use the visp_calibration package to calibrate an Xtion pro live camera. This uses the camera1394 package, which is giving me errors. When I run followed by from the tutorial, I receive a camera not found error and the warnings: I checked the terminal and get these same warnings when i run I looked at OpenNI: Camera calibration file not found and have run: Should I have the yaml files? If so, how do I get them? I can launch the camera, but it needs to publish under the |
