2014-01-28 17:25:23 -0500 | marked best answer | Error while loading nodelet [/normal_estimation] Hi!
I'm using ROS Fuerte Beta 1 on Ubuntu 11.10.
I tried to compile pcl_ros nodelets. There were some errors related to old PCL library API, I fixed them. When I try So, seems that pcl::BoundryEstimation<pointxyz, normal,="" boundry="">::computeFeature(PointCloud) is missing. Where may be problem? |
2014-01-28 17:25:17 -0500 | marked best answer | Separating callback from other modules Hello! May I want something strange, but it interesting programming problem. So, I wrote class-wrapper Sensor that subscribes on topic (like /camera/image) and in callback receives data (like this->callback(Image& data), node.subscribe(..., &Sensor::callback). Data should be prepared by some filters. At this moment, filters called in callback: But I think it is not good. Is there way to separate them from Sensor? Something like this: I think that I missed simple idea of this. |

Today I need in last version of PCL 1.3 ( http://svn.pointclouds.org/ros/trunk/perception_pcl_unstable/ - this one). How should I update current stack? I need some clarification.

2014-01-28 17:23:02 -0500 | marked best answer | Callback never called on c++ Hi! I have a little project on C++. When it was very simple (take frame from Kinect, convert to cv::Mat and show it in window), everything works well. Some days ago I add classificator and after it, in some reasons, callback never calls, as I understand. I can't get, why it so, because of code not changed in general. Can somebody helps me with it?

2014-01-22 07:34:33 -0500 | marked best answer | Appropriate way to store data Hello. I should to store a lot of different data and history of measurements in some storage (data from MS Kinect, ultrasonic sensor, odometry and, for example, data from infrared sensor. Sensors may be used in very different ways, not only for navigation). I wonder, is there some convenient and native way to do this in ROS? May be somebody can share commentaries about http://wiki.ros.org/mongodb ? Or I should to use common DB like MariaDB? Thanks in advance. |
