Abstract
A computer-implemented anomaly detection method in powder-bed-based additive manufacture of a workpiece includes (i) providing an image data set and applying a Principal Component Analysis to said image data to compute a number of image clusters, (ii) applying a clustering algorithm to the analyzed image data and computing respective cluster centroids, (iii) comparing the computed cluster centroids with a set of reference anomaly centroids, wherein based on a match of cluster centroids with the reference, the image data is segmented layerwise into cluster images of a specific anomaly, (iv) transforming the segmented images into a defined color space, such as a Lab color space or greyscale spectrum, and, (v) integrating a pixel information of the transformed segmented cluster images to compute a threshold value for the image data set in order to determine a respective anomaly.
