I would like to do obstacle avoidance using pure Vision approach. I will use ROS and Ubuntu as a framework. The application is in construction industry so would like to detect the material winch is handling by the crane to perform obstacle avoidance . My question is , if its possible to use only vision approach for obstacle avoidance where the distance form the camera to the object can be 30-40m. I will use the zoom for better approach. If its possible to use only Vision camera any starting algorithm to look at it?
Thanks
