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 11):
A method for constructing the trajectory of a first rolling shutter video camera in a three-dimensional scene, that method including:\n a) acquiring a three-dimensional model of the scene, b) storing in an electronic memory a succession of temporally ordered images captured by the first video camera during its movement within the scene, each image including pixels organized in parallel rows, the rows of pixels being captured one after the other so that a non-zero time t \u0394  elapses between the moments of capture of two successive rows of the current image, the memory containing for each pixel of the current image a measurement of a physical magnitude chosen in the group made up of the intensity of radiation emitted by the point photographed by that pixel and a depth separating that pixel from the photographed point of the scene, c) for each current image:\n constructing or selecting from the three-dimensional model of the scene a reference image including pixels that have photographed the same points of the scene as the pixels of the current image, \n estimating a pose of the first video camera at the moment at which the latter captures that current image, \n constructing ( 70 ) the trajectory of the first video camera from the various estimated poses of the first video camera, \n characterized in that the pose of the first video camera is estimated with the aid of a method as claimed in any one of the preceding claims.
