摘要

A method for automatic cr - image - composition comprises the carrying out the following steps for each image in a cr - pair of images. A vertical gradient - image is projected onto a y - axis, around a y - axes - projection (420) to obtain. Be edge positions (candidate) on the basis of white band - edge positions on the basis of an absolute maximum value of the axes - projection (430) identified. An intensity change in consistency identified candidates that have an orientation angle, which is smaller than a threshold value - angle in relation to a horizontal (440). An intensity change in value differences of intensity values verified at two candidates sides (450). A cross corr elat ion - mark for the candidate is calculated, which have an error value, under the effect of a threshold value for the intensity, change, - constancy and the intensity change value is, in that a consistency of the candidates with the image data of the cr - pair is compared (460, 610). A final overlapping is for the cr - pair of images on the basis of the cross corr elat ion - mark identified (620).
