Abstract

A system (100) includes an apparatus (130) for building a component by additive manufacturing, a camera (136), and a computing device (156). When the computing device (156) receives an image (600) of the build plane (112) captured by the camera (136), the image (600) includes a fiducial marker (602) positioned on the build plane (112). The computing device (156) rectifies the image (600) to generate a distortion-corrected image (604), and identifies the coordinates of the fiducial marker (602) in the distortion-corrected image (604). The computing device (156) then compares identified coordinates of the at least one fiducial marker (602) from the distortion-corrected image (604) with corresponding nominal coordinates of the at least one fiducial marker (602) in a coordinate system of the apparatus (130), and generates a coordinate transfer function based on a result of the comparison. The computing device (156) then applies the coordinate transfer function to the apparatus (130) to calibrate a position of the energy beam (132) on the build plane (112).
