摘要： For digitising a surface portion of a three-dimensional article a light source (14) is provided which projects onto the surface portion to be digitised of an article (S) a narrow band of light which extends over the surface portion. In addition, by effecting relative movement between the article and the light source (14) the narrow light band is caused to traverse progressively over the surface portion from one end thereof to the other. A camera (22) comprising a two-dimensional array of cells (26) monitors the location of the narrow light band at successive localities along its traversed path, the cells of the camera being illuminated according to the incidence thereon of light reflected from the narrow beam, and processor means is provided whereby the location of the narrow light band at selected intervals in its traverse are converted to digitised coordinate axis values, along three axes, said values thus being representative of the contour of the surface portion. The apparatus may be free-standing, serving to digitise the surface of an article, e.g. a shoe bottom, in an individual operation, or alternatively may be incorporated in a machine for effecting a progressive operation, again, e.g. on shoe bottoms. The apparatus may also be used for monitoring edges of components and for determining the configuration of marginal portions of such components, in order to enable the operating path of a tool at or adjacent such edge to be automatically determined, or may be used in a machine for pulling an article over a former e.g. a shoe pulling and lasting machine.
