In my research project I deal with a mobile robot that perceives through stereo vision. As the stereo input data I currently use several datasets taken from a passenger vehicle that contain real world photos. The datasets are good to get started but have a limited content so I would need to model my own traffic situations to further work on the stereo vision system.
I am thinking about using some kind of synthetic graphics simulation as the input for the stereo system. What are my options? I can imagine a 3D graphics rendering engine whose output would be fed as the input for the stereo vision could probably be used.
I found there are general robotic simulators available like Gazebo but since I am all new to robotic simulation I do not really know where to begin.
I forgot to write that all my code is a pure C++. I use OpenCV and LIBELAS for stereo vision and Point Cloud Library (PCL) for visualization. All glued together into a single C++ project and compiles into single binary.
