Detailed Description

Manage image requests from one or more clients.

Instances of polled_camera::PublicationServer should be created using one of the overloads of polled_camera::advertise(). You must specify a driver callback that populates the requested data:

void callback(polled_camera::GetPolledImage::Request& req,
              polled_camera::GetPolledImage::Response& rsp,
              sensor_msgs::Image& image, sensor_msgs::CameraInfo& info)
{
  // Capture an image and fill in the Image and CameraInfo messages here.
  
  // On success, set rsp.success = true. rsp.timestamp will be filled in
  // automatically.
  
  // On failure, set rsp.success = false and fill rsp.status_message with an
  // informative error message.
}
