2015-01-19 02:30:28 -0500 | asked a question | How to output the following result to terminal? Hi i am using this code (position calculation) from: http://robotica.unileon.es/mediawiki/... and i was wondering, how could i show the output the result in the terminal. As shown in the code, i added ROS_INFO("x: %f y: %f z: %f", punto.x,punto.y,punto.z ... (more) |

2014-10-07 09:46:51 -0500 | asked a question | How do i know tabletop object detector uses what method to link the object recognition and the position together Hi could someone please tell me how http://wiki.ros.org/tabletop_object_d... link the object recognition and the position together. i don't quite understand the wiki. |
2014-10-07 09:30:55 -0500 | asked a question | How do i use Openni to detect position of object? Is there any tutorial or sample source code to show me how do i use pcl to get depth point of object and detect the object base on colour?? |

2014-10-05 09:08:42 -0500 | asked a question | Opencv for position detection To do position detection, do i need to use Openni's depth map to do the calculations? (using asus xtrion pro live) i detect object base on colour, now i need to detect the object's position relative to the robot. |

2014-09-18 01:18:01 -0500 | commented answer | How do i use ros TF to capture object position based on colour and calculate relative distance? Oh yes, i'm using this website's colour detection and tracking to detect the object. http://opencv-srf.blogspot.ro/2010/09... Right now i need to figure out how to do position detection. It would be great if you could teach me on that. Thanks for the help! |
2014-09-18 01:16:00 -0500 | commented answer | How do i use ros TF to capture object position based on colour and calculate relative distance? Hi yes thanks for all that information. Regarding what i'm trying to achieve, it is to actually allow the camera to detect on object based on the colour. After that, the camera will calculate the distance of object from camera. |

2014-09-17 07:17:49 -0500 | commented answer | How do i use ros TF to capture object position based on colour and calculate relative distance? Oh... i didn't know that... so i have get opencv to calculate distance and position?? May i know whether there is any tutorial on that? Sorry not that good at opencv. |
2014-09-17 04:28:42 -0500 | asked a question | How do i use ros TF to capture object position based on colour and calculate relative distance? Hi im currently doing position detection. By using Opencv color(red) detection i detect the red object and now i want to publish it in the tf and show where and the distance between the object and camera. |
