测量异形板料表面变形的自动操纵系统可以帮助汽车设计师确定汽车的零部件,诸如车门等能否在不出现皱折或裂痕的情况下一次模压成型。该系统能以比现行的人工测量方法快100倍的速度分析板料的变形情况。这种新系统使用摄影用抗蚀剂,在将要模压的板料上绘制出均匀的方格网络。方格的尺寸根据零件大小从4.67～9.53mm不等。当板料被加工成所需部件的形状后,电视摄像机便可以从不同的角度摄下两张网格视图。网格的相交点以数字显示,并被输送到计算机内,然后利用两张视图之间对等部分的几
An automated control system that measures the deformation of a profiled sheet surface can help a car designer determine whether parts of a car, such as a car door, can be molded once without wrinkles or cracks. The system can analyze the deformation of sheet metal 100 times faster than the current manual measurement method. This new system uses photographic resist to draw a uniform grid of squares on the sheet to be molded. The size of the grid varies from 4.67 to 9.53mm depending on the part size. When the sheet is processed into the shape of the desired part, the television camera can take two grid views from different angles. The intersection points of the grids are displayed numerically and transported to the computer, and then the couple of sections of the two views are utilized
