hi everyone.

I spawn my robot model with launching robot_spawn file, it 's a sdf robot model and it has a camera that uses libgazebo_ros_openni_kinect.so driver.

robot sapwns successfully and I can get image from it's topic and $(camera_topic)/camera_info topic published successfully.

my question is: info published by camera_info is true? should I calibrate my camera? how can I calibrate my virtual camera?

I'm not an expert, but virtual cameras (I'm assuming Gazebo plugins here) are typically implemented as "perfect cameras" (they typically have the distortion matrix in the camera info msg set to zeros). Calibration would not make sense in those cases.
