1. Apparatus for imaging, comprising:

  • a representation generator arranged to generate a three dimensional representation of a scene;

    an image segmentation process arranged to identify objects located at different depths in the scene;

    at least one visible light imaging sensor arranged to obtain a visible light image of the scene;

    at least one infrared imaging sensor arranged to obtain an infrared image of the scene; and

    an image overlaying processor arranged to;

    overlay the infrared image and the visible light image onto the three dimensional representation of the scene to produce an multispectral three dimensional representation of the scene; and

    manipulate the overlaid infrared image in the multispectral three dimensional representation of the scene according to the depths of the identified objects such that;

    the infrared image is not overlaid onto objects in the scene that do not satisfy a predetermined depth requirement so that a palette of false colors used to represent temperature data in the infrared image is adjusted to extend over the range of temperatures observable at objects satisfying the predetermined depth requirement; and

    the visible light image is overlaid onto objects in the scene that do not satisfy the predetermined depth requirement.
