METHOD AND APPARATUS FOR DISPLAYING STEREOGRAPHIC IMAGES OF A REGION

The present invention relates to amethod of displayingstereographic images of a region R.The method comprises: moving a vehicle (10) relative to the region, the vehicle carrying a camera system (12) for acquiring images I of the region; during movement of the vehicle relative to the region acquiring a series of temporally sequential multiple images(I1, I2,) of the region at respective multiple different spaced apart locations (L1, L2,) of thevehicle relative to the region; displaying successive stereographic images of the region during movement of thevehicle relative to the region. 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 in the series one from the other. The method comprises the step of varying the temporal spacing of the first of said multiple images and the second of said multiple images according to a velocity of the vehicle relative to the region so that 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.
