I've got Gazebo 2.2.3 and ROS Indigo set up, and I have a plugin that allows a stereo camera to publish images from Gazebo to ROS. The issue now is that I need to somehow either save the images or have access to the pointers for the camera images. Is there a Gazebo plugin that does that?
I recently had a similar question, the answer to which might help you as well:
By adding
<save enabled="true">
<path>/tmp</
</save>
to your camera model you can save the images in a directory of your choosing.
My original plan was to write a C++ program that takes the sensor_msgs/Image topics published by Gazebo and save them when the user inputs a command. If save is not enabled in the camera, are there still pointers for the camera images that would allow me to access those images?
Ok, I gave it a try, and the method you suggested works. Thank you. To further clarify the code issue, I would like to write a program that saves the most recent frame captured by the camera (not all the frames continuously captured) when the user enters a certain command.
