摘要： The invention relates to a method for determining the geometric parameters indicating the movement of a camera, which involves: recording a set of P video images of an action carried out over at least one segment of a surface having a texture, wherein each image p is, each time, at least partially segmented into a number N of areas; selecting, for each of the images of said set, a subset of M (M ≤ N) of said areas, each of the M areas having an image element continuing said texture; each time, forming a pair of the images p-i and p so as to then create a series of S (1 ≤ s ≤ S) geometric projections of said selected M areas and determine a rate of coincidence between the projected areas; and searching, from among the S geometric projections, for the geometric projection that provides the highest rate of coincidence between the areas of the images p-i and p.
