Method and apparatus for displaying stereographic images of a region
First Claim
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, andvarying 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.

Abstract
The present invention relates to a method of displaying stereographic 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 the vehicle relative to the region; displaying successive stereographic images of the region during movement of the vehicle 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.

19. A method of displaying stereographic images of a region, the method comprising the following steps:
-
moving a vehicle relative to the region and outputting movement data from an on-board system corresponding to vehicle movement; acquiring images of the region with a camera system comprising a camera mounted on the vehicle and orientating the camera so that it is along a line of sight with the region irrespective of movement of the vehicle, and outputting orientation data corresponding to the orientation of the camera; 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 whereby the images are acquired at different respective image vectors 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 image vector and a second of said multiple images acquired at a second image vector which are temporally spaced apart in the series one from the other, and rectifying one or both of the first of said multiple images and the second of said multiple images according to an angle between the first image vector and the second image vector in the displayed stereographic image dependent on the movement data and orientation data; 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 control unit is configured to control the display so that 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 stereographic images having a required depth can be displayed independent of the velocity of the vehicle relative to the region.
