How to select version OpenCV in ROS ?

edit

Hi C4ncelot,

Thank you so much for your support. I so glad, and I going to try this way to solve it.

And, do you know the most advantages of Ros? I am know not clearly about it.

I hope you will response me and discuss about it.

Thank you again!

@ToanJunifer, glad to help. I'm not the right one to explain full advantages of ROS in detail. Try to look at q#200423 for some basics. ROS is basically set of libraries, tools, communication layer etc...

... everything you need to build some robots. Image if ROS wouldn't exist. How would you e.g. program some mobile robot to navigate through unknown environment? What would you need to code except for your main algorithms? What about communication between your code? What about architecture? ...

... what about hardware drivers, debug tools etc.? Before ROS robotic research was primarily done at universities and not many universities were collaborating with each other. And when they did, each collaboration group had their own solution to the problem described above...

... There wasn't one solid approach everybody would use and improve. Now with ROS you basically don't need to solve above problems. Learning ROS is not easy, but it's a lot easier than solving everything on your own. Collaboration between the community is great advantage of ROS thanks to the...

... modularity of ROS packages. If you want to use package e.g. for obstacle avoidance using laser range finder you basically download it, look at the documentation about that particular package, find out input/output topics and connect it to your packages with subscribers/publishers of your own.

Hi @l4ncelot, Do i need to copy python3.4/dis-package folder to /opt/ros/indigo/lib/ before run first line?

@ToanJunifer, Q1: No, just use the path you're working with. My path was just example, you need to replace it with yours. Q2: Sorry, I forgot about the escape characters. I've updated the syntax.
