ros service does not start #10

Hi, thank you for openning this code!

I run this code, but meet some problem.
I find that the "startInfinitam" service does not running.

the caller is :
InfinitamNode::InfinitamNode(int& argc, char** argv)
{
...
std::cout << "calling..." << std::endl;
// Initialize service.
start_infinitam_service_ = node_handle_.advertiseService(
"start_infinitam", &InfinitamNode::startInfinitam, this);

...
}

and the service function is :

bool InfinitamNode::startInfinitam(std_srvs::SetBool::Request& request,
std_srvs::SetBool::Response& response)
{
LOG(INFO) << "startInfinitam start!";
std::cout << "startInfinitam start!" << std::endl;

...
}

the screen out put is

I have published the topics the infiniTAM listens to
"/camera/rgb/image_raw"
"/camera/depth/image_raw"

And I can run infiniTAM without ROS

I have no idea how this come, since I am not familiar with ROS, can you give me som advice?
