Abstract:
A method for estimating the speed a first video camera when it captures a current image of a three-dimensional scene, the current image including pixels. The method includes storing a reference image corresponding to an image of the same scene captured by a second video camera in a different pose, the reference image including pixels. The method also includes storing the current image, containing for each pixel of the current image the measurement of a physical magnitude measured by that pixel, which is the same as the physical magnitude measured by the pixels of the reference image. The method further includes storing for each pixel of the reference image or of the current image the measurement of a depth that separates that pixel from the point of the scene photographed by that pixel, estimating the pose and speed of the first video camera.

Claim (Index 7):
The method as claimed in any one of the preceding claims, wherein the value of the physical magnitude at the level of the point (p*; p w5 ) of the reference image, called the reference point, is constructed:\n by selecting points adjacent the reference point, each adjacent point corresponding to the projection onto the plane of the reference image of a third point the coordinates of which are obtained by shifting the second point a distance T 2 (\u2212\u03c4x vR ), where t is a time elapsed since the beginning of an exposure time t e , that time being less than or equal to the exposure time t e , and T 2 ( . . . ) is a function that integrates the speed x vR  during the time t, each adjacent point corresponding to a respective value of the time t and the time t e  being equal to the exposure time of the first video camera, then by averaging the values of the physical magnitude at the level of the selected adjacent points and the reference point so as to generate a new value of the physical magnitude at the level of the reference point, that new value constituting an estimate of that which would be measured if the exposure time of the pixels of the second video camera were equal to t e  and if the second video camera were to move at the speed x vR  during the exposure time t e , the values of the physical magnitude at the level of the adjacent points being obtained from the measurements stored in the reference image and the coordinates of the adjacent points.
