I am bring up some camera models for Gazebo. These cameras have different FOV, for example, horizontal 61 degree and vertical 47.7 degree. So when I am looking the SDF sensor/camera specification (http://sdformat.org/spec?elem=sensor) there is no tag for a vertical FOV. But If I am looking at the Camera class reference (http://osrf-distributions.s3.amazonaws.com/gazebo/api/dev/classgazebo_1_1rendering_1_1Camera.html) there are both available, vertical and horizontal.
Is this right? Is it possible to set the vertical FOV using the sdf file or have I to increase the functionality of the camera plugin by my own? What would you prefer?
