摘要：本文提出了视觉检测概念，建立了用于三维尺寸测量的视觉检测系统。系统使用了两种不同类型的视觉传感器，以完成空间不同点三维坐标值的测量。将该系统用于一汽Au-di—100轿车白车身左侧围的测量，取得了令人满意的结果，与坐标测量机（CMM）的测量结果进行比较，两者具有较好的一致性。

Abstract：In the paper，the visual inspection conception is presented and a visual inspection sys-tem is established for 3-D dimensional measurement.In the system two kinds of visual sensors（contour sensor and surface sensor）are utilized to complete 3-D coordinate measurement of differ-ent points in space.The system is applied to dimensional measurement of left sideframe on Audi-100 body-in-white and the satisfactory results are achieved.The statistical measurerment data show the readings from the system are relatively identical to those from the coordinate measuring machine（CMM）.
