Hi, I am new to ROS. I have a 4 camera stereo set using 4 synchronized cameras that are not supported by ROS. This is not unlike what PR2 uses. I would like to use these camera with ROS. What is the best way to do this? 1. Do I need to write my own "driver"? That is code that interfaces with the camera APIs and publishes to ROS? 2. In that case, what do I publish? Do I give only raw image output or is there a way to publish a stereo pair? 3. Are there any examples for how to do this, e.g. from some other stereo cameras? 4. What is the easiest way to do this? As I said I am new to ROS. Thanks, Adi
