2015-04-23 05:58:15 -0500 asked a question Implementing the Bayesian Occupancy Filter on ROS

Hello all,

I'm new in ROS and I want to implement the Bayesian Occupancy Filter introduced by Tay et al. in : An efficient formulation of the Bayesian occupation filter for target tracking in dynamic environments.

I have already studied that publication and I'm wondering if there is ROS packages that allow me to implement the BOF filter on ROS.

Thanks in advance.

Hi, I suggest to you to take a look on local_map on this page : http://wiki.ros.org/local_map . It's probablly what you're loocking for.

Hi,

I finally found a node ROS that can do that. But can be run only on ROS Indigo. More information on this page : http://wiki.ros.org/local_map

2015-03-24 09:38:34 -0500 asked a question Run local_map on ROS Hydro

Hi, First off all, I want to thank you for your excellent package! It runs amazingly on ROS Indigo.

Next, I would like to run local_map on ROS Hydro so I copied the code on my workspace and run catkin_make. Unfortunately, it doesn't work. Is that any way to run local_map on ROS Hydro ?

Thanks.

Thanks afranceson. I'll try Costmap2D then.

2015-03-23 17:41:11 -0500 asked a question Laser scan to probabilistic map based on occupancy grid

Hi all,

I would like to transform laser data (LaserScan) in a local 2D occupancy grid (OccupancyGrid). I tried to use "gmapping" and it worked well. But gmapping builds a global map while I only need the local one.

Is there a simple solution (a package or a node) to build a local map around the robot? Could you please tell me what should I do in details? or show me some references?

Thank you.

Thank you for your response. It's exactly what I need. However, is there any other package (more simpler) which converts laser data in an occupancy grid?

2015-03-23 08:14:52 -0500 commented answer Get only the current map from GMapping

Yes, you understand me well. the topic "/map" provides a global map but I need the local one. Is there any modification that I can make on the source scde of GMapping to extract only the local map?

2015-03-23 07:29:11 -0500 commented answer Get only the current map from GMapping

Hi again, I think that there is a miseard. I mean by "current map" the map related to the robot (the local map). In fact, my robot doesn't provide odometry data so I just want to see the current map provided with laser scan in fixed location (x = 0, y = 0, theta = 0).

2015-03-23 06:11:29 -0500 asked a question Get only the current map from GMapping

Hi, I'm new in ROS and I want to do a DATMO application with laser scan. For the first step of this application, I only need to get the current map created by GMapping. Is that possible?

Could you please tell me what should I do in details? or show me some references?

Thank you.
