目前，金属产品生产中最耗时、成本最高且重要的阶段之一是检测过程，其中使用自动光学检测和图像处理技术来识别生产缺陷。检测金属表面，特别是光滑金属表面上发生的缺陷是很困难的。检测过程中的主要问题涉及复杂的反射和噪声。基于二维平移不变 RI-样条小波变换，开发了一种针对光滑镀铬 ABS 树脂表面的新型自动缺陷检测系统。令人鼓舞的实验结果证实，自动检测系统可以准确地检测光滑金属表面的缺陷。
Currently one of the most time-consuming, costly and important phases of metal products production is the inspection process, in which automated optical inspection and image processing techniques are used to identify production defects. It is difficult to detect defects occurred on metallic surface, especially on smooth metallic surface. The major problems in inspection process involve complex reflections and noise. Based on 2-D Translation Invariant RI-Spline Wavelet Transform, a novel automated defects detection system is developed for smooth chrome-plated ABS resin surface. From encouraging experimental results, it is confirmed that it is possible for automated inspection system to accurately detect defects on smooth metallic surface.
