Abstract: A method is disclosed for correcting deviations in a production process of an article. Initially, measured 3D surface coordinates of a first article are obtained and used to create a virtual image of the first article that is displayed on a display apparatus that is fastened to the user's head. The virtual image is superimposed on a predefined model image of the article which is also displayed on the display apparatus to enable the user to detect any region(s) where the measured first article deviates from the predefined model. The user is then able, via a gesture (e.g., hand movement) or head movement, to select a particular region of deviation and control the desired corrective action to be performed on subsequently produced articles. The present method thereby enables the experienced user to subjectively select the region(s) requiring correction action and the degree and type of corrective action to be taken.

Abstract: A method for correcting deviations in a production process of an article, including: a) measuring surface coordinates of a first article, b) representing, in three dimensions, real measurement values from measuring the surface coordinates with a display apparatus that is fastenable or fastened to a user's head, c) representing, in three dimensions, a predefined model of the article using the display apparatus, d) comparing the predefined model to the point cloud or the point mesh, e) selecting at least one region from the point cloud or the point mesh which deviates from the predefined model, f) manipulating this region of the point cloud or the point mesh by means of the gesture or head movement control such that the point cloud or the point mesh in this region is matched to the predefined model, or approximated to the predefined model, or moved beyond the predefined model, g) transmitting at least one value of a deviation between the point cloud or the point mesh and the point cloud/point mesh obtained b
