The present invention provides a system and method for generation of nitrogen enriched air for inerting aircraft fuels tanks. The heat exchanger is provided with two sections and inlets and outlets to the sections to cause streams of the fluids to flow within the two sections parallel to the length of the heat exchanger between central locations and the ends of the heat exchanger. In one embodiment, the radial support sidewall includes two spherical contact points, and the axial support sidewall includes one spherical contact point. An image transformation unit transforms one image input by a first camera using each of a plurality of transformation parameters each representing a geometrical relationship among a predetermined plane, the first camera, and a second camera, and generates a plurality of transformed images from a view position of the second camera.
