2012-01-11 12:35:41 -0500 | answered a question | Finger detection doesn't work well. I have already post it to Kinect+ROS mailing list. se7oluti0n, who answered my question and it did work for me. Let me copy this msg for you all. I have had the same problem before but I have solved it by edit some value in this piece of code : in function void radiusFilter(int nnthresh, double tol) of analyze_hands.cpp: } this functions will separate palm and digits by look at each point of the hand point cloud, If number of points around that point ( within radius tol ( 2nd parameters )) is bigger than (530-500*distfromsensor), this point will belong to palm and vice versa. replace 530 and 570 with your value ( may be the size of the cluster depends on people ) or edit radius tol my case is 830 and 870 and it worked. Hope that helps.. |
2012-01-10 03:25:14 -0500 | asked a question | Finger detection doesn't work well. Hi there, I followed the instruction on finger detection HERE. For my experiment, the skeleton tracking and hand detection did work well, but I had problems on finger detection. According to this video http://www.youtube.com/watch?v=haCyDo7y3BE. The result suppose to be like in the vdo, but not for me. I have already looked through the code and found that on ~/kinect_demos/mit-ros-pkg/kinect_utils/hand_interaction/src/analyze_hands.cpp which is my clusters is always 0. Here is a piece of my console. I stuck on what's wrong with my configuration? Can anyone point me out of this problem? Thanks in advance. Mintra. |
2012-01-01 17:36:22 -0500 | marked best answer | How to autonomous localization on TurtleBot? You're on the right track. Tutorial #3 from the navigation page is your best bet. |
2011-12-26 20:52:48 -0500 | commented answer | How to autonomous localization on TurtleBot? @IsaacSaito Oh I see. Thanks for your information. :))) |
2011-12-26 13:15:56 -0500 | commented answer | How to autonomous localization on TurtleBot? Thanks a lot Ryan. One thing I found on that page is I have to localize it by drag in the direction where TurtleBot is pointing, right? So, if I want TurtleBot to drive automatically and localize by itself llike this vdo http://www.youtube.com/watch?v=nWvLX6xmoAw , you have any idea how to do this? |

2011-12-26 00:22:25 -0500 | asked a question | How to autonomous localization on TurtleBot? Hi all, I am very new on ROS and TurtleBot. I have done the tutorial on the TurtleBot where located on this link http://www.ros.org/wiki/Robots/TurtleBot . The thing is I would like to make a TurtleBot to autonomous localization which means the user have not to localize it by themselves. Moreover, I want TurtleBot can walk thought in a known map, and localize it. I am working on this tutorial as well which is related to AMCL. http://www.ros.org/wiki/navigation , but I don't know it will reach to my propose or not? So, could you please suggest me what is the first thing I should do? Best, Mintra. |
