Abstract
A method includes capturing an image of a powder bed with a visible light camera that shares an optical axis with a laser beam. The laser beam is configured for heating the powder bed. The method also includes increasing first intensities of first pixels of the image that are indicative of foreign objects within the image and normalizing second intensities of second pixels of the image that are indicative of uneven illumination of the powder bed. The method also includes processing the image via contrast limited adaptive histogram equalization after increasing the first intensities and after normalizing the second intensities. The method also includes using graph-based image segmentation to identify third pixels of the image that correspond to an area of the powder bed that has been processed by the laser beam and indicating the third pixels via a user interface.
