摘要： A method for calculating the geometry of a last for customised footwear comprises the following steps: collection in a data base of 3D models of lasts, creation of a grid of lasts having different measurements in terms of length and of fitting, acquisition of a 3D model of a foot, identification of a sub-set of at least two lasts having measurement parameters close to those of the foot, deformation of the 3D model of the foot to follow the course of the 3D last model, identification of some areas of interest of the 3D model of the foot, deformation of the 3D model of each of the lasts selected in the areas of interest so as to compensate for differences between the 3D model of the last and the 3D model of the foot and selection, on the basis of the residual errors, of the final last to be reproduced.

摘要： Method for checking the set-up of the suspension of motor vehicles, in particular for measuring the total toe-in and camber angles of the wheels. Two or preferably four videocameras in predetermined fixed positions are used, said videocameras being able to define a fixed spatial reference system, each videocamera being associated with a respective wheel. The method comprises the steps of: identifying, for each wheel, its profile projected onto the optical sensor plane of the respective videocamera, as the locus of the points of greatest variation in luminous intensity; calculating mathematically, using the least square fit method, the conic section which best approximates the profile thus obtained; calculating, from the equation of this conic section and from the known coordinates of the position of the videocameras in the fixed spatial system, the two angles which define - with respect to a vertical longitudinal plane and with respect to a horizontal plane - the orientation of a bundle of parallel planes which intersect, in the form of a set of circles, the cone obtained projecting into space the conic section "viewed" by the videocamera, these angles representing the total toe-in and the camber of the wheel, respectively.
