1. A system for detecting the presence and location of flaws in a composite layup material deposited on a mold by an automated fiber placement head, utilizing a three-dimensional point cloud representing a top surface of the composite layup material, comprising:
a processing device; a laser line scanning device in communication with the processing device; and a non-transitory computer readable memory device in communication with the processing device, the non-transitory computer readable memory device storing instructions that when executed by the processing device result in:
receiving, by the non-transitory computer readable memory device, programmed three-dimensional features of the top surface of the composite layup material, the top surface comprising a region of one or more courses of composite layup material;determining, by a scanning of the top surface conducted by the laser line scanning device, the three-dimensional point cloud representing the top surface of the composite layup material;receiving, from the laser line scanning device and by the processing device, information describing the three-dimensional point cloud representing the top surface of the composite layup material;determining, by the processing device and based on an analysis of the three-dimensional point cloud representing the top surface of the composite layup material, the analysis comprising an execution of a manufacturing flaw detection algorithm, a location of at least one manufacturing flaw on the top surface of the composite layup material;determining, by the processing device and based on an analysis of the three-dimensional point cloud representing the top surface of the composite layup material, the analysis comprising an execution of a feature detection algorithm, information descriptive of a location and a characteristic of one or more as-made features on the top surface of the composite layup material;comparing, by the processing device, the information descriptive of the location and the characteristic of the one of more as-made features on the top surface of the composite layup material with the programmed three-dimensional features of the top surface of the composite layup material;identifying, by the processing device and based on the comparison and an execution of at least one as-made flaw detection algorithm, a presence and location of one or more as-made flaws on the top surface of the composite layup material;recording, by the non-transitory computer readable memory device, the presence and location of the one or more manufacturing flaws and the one or more as-made flaws on the top surface of the composite layup material; andtriggering an outputting indicative of the locations of the one or more flaws on the top surface of the composite layup material. |
