2017-10-16 17:36:39 -0500 | marked best answer | Best Motion Capture System to work with ROS My laboratory is looking for a motion capture system (mocap) to buy, like Optitrack, Vicon and Qualisys. There are a lot of questions about which equipment is better. As I am working with ROS, I would like to know which motion capture system is best integrated with the newer frameworks (Indigo, Jade, Kinetic ...). In addition, I would like to have some opnions about the ROS users experiences with the different mocaps systens. |

2016-06-16 15:52:48 -0500 | asked a question | Ar_track_alvar bundle with differents markers size Hi everyone, I am working with ar_track_alvar package. I would like to use the node "findMarkerBundlesNoKinect" to detect multiple bundles, but in each bundle the master tag's size is different from the others. Is it possible? The bundle it's similar the image bellow. The master tag is the beggest on the center. Another issue is that I tried to modify the marker_size, max_new_marker_error and max_track_error parameters in the bundle launch file, but it didn't affect nothing. So, what is necessary to these parameters work? |

2015-07-15 16:36:20 -0500 | asked a question | ar_track_alvar pose not returned Hello folks, I am tring to use the AR_TRACK_ALVAR (version 0.5.1) on my Indigo version with Ubuntu 14.04.1 64 bits. I already have used this package on Fuerte and it works perfectly. However, I have experienced some drawbacks on Indigo version. I get it on git repository and compile, and these steps goes ok. When I show the markers, the node (individualMarkersNoKinect) identifies the tagIDs, but the package can't estimate its positions and orientations (it present only zeros). I'm using the usb_cam package as I did on Fuerte. I already look my TF Tree and saw that everything probably runs OK, as in the image: I did calibration of the camera adjusting the KDRP parameters and I had succesful on this step. This is the launch file that I have used. By this description, can you tell what is going wrong or what am I missing? Thank you. |
