2017-03-22 05:10:59 -0500 | commented answer | How to use arbitrary version of OpenCV That did the trick, thanks. It's the same version as the one under Kinetic,3.2.0, but it's better to use the most recent in github, right? |
2017-03-22 05:01:00 -0500 | commented answer | How to use arbitrary version of OpenCV To what value should i set OpenCV_ROOT_DIR? I tried to set it to opencv cloned folder in my home directory and it didn't work. Then i tried to set to /usr/local/include and it also didnd't work. |

2017-03-21 20:58:51 -0500 | asked a question | How to use arbitrary version of OpenCV Hi, i have ROS Kinetic installed and it comes with OpenCV. I also have the latested OpenCV that i downloaded from github and installed in /usr/local. The following code that i wrote will always use OpenCV that came with the ROS installation, can i make it use an arbitrary version of OpenCV that i have on the system? Here's the CMakeLists.txt file: When i run it i get: UPDATE I found a way to make it work. I'am open for alternatives to this. This is the CMakeLists.txt that i have now: |

2017-03-16 12:27:50 -0500 | asked a question | Getting started in the world of drone programming Hey guys, I'am new in this site but i think i will pretty active in the next few months! My idea is program a drone so that it follows objects alone. I have some programming experience but i don't yet have a drone. I know that the Parrot drones can be programmed with ROS and i get the idea that people who get into this projects follow that path, i'am i correct? I found out recently that it's also possible to program DJI drones, how does that work? I need the drone to have around 30 minutes of battery(ideally more, but if not possible that will do). The camera needs to be decent as well and i would also like the drone to be robust. (not fun burning $$). So based on the above what drone would you recommend me, and how should i tackle this? (i'am thinking i need to study computer vision and learn to use OpenCV, what more?) |
