Abstract
Method and device for stabilizing images obtained by a video camera of an environment with objects moving along lanes. The method a first stage of determining in first images obtained by the camera, portions corresponding to the movement lanes, determining the remaining second portions complementary to the first portions, determining, in the second portions, the reference position of the image point corresponding to a first stationary object point, and a second stage of determining in at least one second image taken after the first images, the vector that corresponds to the movement of the image point relative to its reference position determined by the first images, and processing the second image as a function of the modulus and direction of the vector such that, relative to the three-dimensional frame of reference the image point returns to its reference position.
