Method and system for recording images of surfaces of moving objects with reduced distortion
Abstract:
A method of capturing an image on a surface of an object by line sensor(s), wherein consecutive line images are taken from a plurality of surfaces or surface portions having a different inclination to a given reference plane with a predetermined frequency during a relative movement of the object with regard to the line sensors(s) and a two-dimensional first image of the surfaces or surface portions is formed from these line images, includes resampling the two-dimensional first image so as to reduce the surface resolution of an image or of images of one or more surfaces or surface portions with regard to a direction oblique to the direction of the lines corresponding to consecutive line images taken by a line sensor in such a way that differences in the surface resolution of images of surfaces or surface portions with different inclination to the reference plane are reduced or eliminated.
