摘　　要：利用COMET L3D对钣金件进行了点云数据的获取,将钣金件实物模型的立体信息转换成了计算机能直接处理的高精度三维数字模型,随后利用点云数据对钣金件进行了逆向重构,并对逆向重构过程中曲面的重构以及精度控制进行了详细分析。最后得到了精度较高的钣金件重构模型。逆向工程在钣金件设计过程中的应用弥补了传统正向设计的局限和不足,在保证精度的前提下实现模型的快速重建,从而缩短了钣金件的设计研发周期,降低了设计成本。Using COMET L3D to get point cloud data of sheet metal parts, sheet metal pieces of physical model of the three-di- mensional information into the computer can deal directly with high precision three-dimensional digital model, then using the point cloud data to reverse remodeling, sheet metal parts and in the process of reverse remodeling of surface reconstruction and accuracy control are analyzed in detail Finally obtained the high precision sheet metal pieces of reconstruction model. Reverse engineering in the application of sheet metal parts design process to make up for the limitation of the traditional top-down design and the in- sufficiency, under the premise of guarantee accuracy rapid reconstruction of the implementation model, so as to shorten the devel- opment cycles of sheet metal parts design, reduce the design cost.
