Vision is important part of robotics and frequently it is unavoidable component of control loop. E.g. many clothes/garment handling algorithms rely on visual cues in deciding how to proceed. The question is - does simulation environments (Gazebo or some others) allow one to design world with robot and garment and simulate not only garment dynamics but simulate also what robot sees, how robot perceives garment in each simulation step? If it is not possible to simulate vision then how to simulate algorithms with vision as component of control loop?
Maybe simulation of vision can be good research theme? Are here some trend or good articles about it? Some initial projects that could be expanded?
Actually - it can be stated as more general question - is it possible to simulate sensors in Gazebo? E.g. food handling (soft-body handling) can involve tactile sensors. In principle Gazebo can calculate deformation and forces of soft-body and format these data as the simulated values of sensor readings. Maybe similar mechanism can be used for simulation of vision as well?
