Abstract:
1. A method of displaying stereographic images of a region, the method comprising the following steps: moving a vehicle relative to the region, the vehicle carrying a camera system for acquiring images of the region, during movement of the vehicle relative to the region acquiring a series of temporally sequential multiple images of the region at respective multiple different spaced apart locations of the vehicle relative to the region, displaying successive stereographic images of the region during movement of the vehicle relative to the region, wherein each stereographic image comprises a first of said multiple images acquired at a first location and a second of said multiple images acquired at a second location which are temporally spaced apart by a number of images in the series one from the other, determining a velocity of the vehicle relative to the region, and varying the temporal spacing of the first of said multiple images and the second of said multiple images according to said velocity, wherein at a first velocity of the vehicle relative to the region the first and the second of the multiple images are spaced apart by a first number of images in the series and at a second velocity relative to the region the first and the second of the multiple images are spaced apart by a second number of images in the series, wherein the spatial separation between the first and the second locations is not less than a predetermined amount so that the stereographic images having a required depth can be displayed independent of the velocity of the vehicle relative to the region.
