Anaglyph Ltd. (London, U.K.) has introduced the PlyMatch System, a video-based ply placement aid designed to help operators manually position plies correctly in hand layup applications. The system displays, together on a single computer screen, both a live video image of the actual tool and layup and a superimposed, computer-generated image of the structure with the virtual composite ply already in place. By viewing the compound image, the operator can accurately align the actual ply with its image as drawn by the software. The data for the computer-generated images can originate from virtually any CAD application or from Anaglyph’s Laminate Tools software application. The position and direction of the digital camera in space can be changed. A coordinate measuring machine (CMM, included in the system package) continuously and automatically updates the camera’s position in the software, enabling accurate positioning of the computer-drawn image as the live video image changes.
