Abstract: A system includes an image realisation device for forming a source image and projection optics for rendering a display image on a display screen, wherein the display image is a virtual image corresponding to the source image. The projection optics have an optical axis, and the image realisation device includes a first image realisation surface at a first distance along the optical axis and a second image realisation surface at a second, different distance along the optical axis. The first and second image realisation surfaces overlap, and the first and second image realisation surfaces include multiple regions, each region switchable between a transparent state and an image realisation state such that the source image may be formed on a region of the first or second image realisation surface and projected through the projection optics to render the display image on the display screen at a first or second apparent depth.

Abstract: An imaging system includes an image realisation device and projection optics for rendering a display image on a display screen. The image realisation device includes a first image realisation surface tilted relative to an optical axis such that a first point in a first region of the image realisation surface is at a first distance from the focal point of the projection optics and a second point in a second region of the image realisation surface is at a second different distance from the focal point of the projection optics. A first source image formed on the first region and projected through the projection optics renders the first display image on the display screen at a first apparent depth, and a second source image formed on the second region and projected through the projection optics renders the second display image on the display screen at a second apparent depth.

Abstract: Embodiments of the present invention provide a system for determining a location of a tow hitch (280) mounted to a vehicle (250), comprising imaging means (260) disposed in relation to the vehicle to output image data corresponding to an image (105), and processing means (200, 210) arranged to receive the image data (270), wherein the processing means is arranged to select image data corresponding to a region (310) of the image and to search within the selected data for image data corresponding to the tow hitch (280) to determine the location of the tow hitch within the image.

Abstract: A crest detection system (10, 19, 185C) for a vehicle (100), the system comprising a processing means (10, 19) arranged to receive, from terrain data capture means (185C) arranged to capture data in respect of terrain ahead of the vehicle by means of one or more sensors, terrain information indicative of the topography of an area extending ahead of the vehicle (100), wherein the processing means (10, 19) is configured to, in dependence upon a predicted path of the vehicle (100) over said terrain extending ahead of the vehicle (100), determine that a crest exists in the predicted path in dependence at least in part on the detection of a discontinuity in terrain along the predicted path ahead of the vehicle (100) based on the terrain information, and information in respect of slope of terrain before the discontinuity.
