I think the answer of paulbovbel is the correct one. You just forgot to put a space in this line (between the >> ):

 distance_sub = nh.subscribe<pcl::pointcloud<pcl::pointxyz>>("/distance_sensors", 1, &SafetyBelt::distanceCallback, this); 

Change to this:

 distance_sub = nh.subscribe<pcl::pointcloud<pcl::pointxyz> >("/distance_sensors", 1, &SafetyBelt::distanceCallback, this);
