Abstract (en)
[origin: WO2015071458A1] This method comprises the estimation of the speed XvR of displacement of a camera by searching for the speed XvR which minimizes a discrepancy directly between: - a first value of a physical quantity at the level of a first point (p*) of a reference image, and - a second value of the same physical quantity at the level of a second point (pw2) of a current image, the first value of the physical quantity at the level of the first point (p*) of the reference image being constructed: - by selecting neighbour points of the first point (p*) as a function of the speed XvR and of a time te equal to the exposure time of the first camera, then - by averaging the values of the physical quantity at the level of the neighbour points selected and of the first point in such a way as to generate a new value of the physical quantity at the level of the first point.
