CAMERA CALIBRATION IN ADDITIVE MANUFACTURING USING LASING ON PLATE
This abstract first appeared for US patent application 20240424563 titled 'CAMERA CALIBRATION IN ADDITIVE MANUFACTURING USING LASING ON PLATE
Original Abstract Submitted
systems and methods involved in additive manufacturing are disclosed. calibrating one or more optical cameras of an additive manufacturing system includes controlling one or more laser energy sources to form a design on a surface. the design is a two-dimensional array of elements, at least two elements of the array differing in shape and/or orientation from each other. the method also includes obtaining one or more images of the design based on using the one or more cameras, and analyzing the one or more images by implementing one or more algorithms to determine or update parameters for each of the one or more cameras. the parameters of each of the one or more cameras include extrinsic parameters relating a printer coordinate system of the one or more laser energy sources and an image coordinate system of the camera, intrinsic parameters controlling image distortion resulting from lens properties, or both.
