ISRA压花玻璃在线检测技术方案

1.2 Outstanding Features of ISRA Surface Inspection ISRA 表面检测的主要特点 ISRA VISION SYSTEMS AG is working in the field of surface inspection for more than ten years and has proven the performance and reliability of the offered surface inspection systems in many application areas. ISRA 公司涉足表面检测领域已有了超过十年的时间，所提供的表面检测系统的性能和可靠性已 在许多应用领域得到验证。 The inspection system PATTERNSCAN-Ribbon offers continuous, inline- and 100%inspection of web materials at highest production speeds. PATTERNSCAN-Ribbon 检测系统可以在最高的生产速度条件下对连续的/非连续的材料提供连 续的、在线的、100％的检测。 Due to the exclusive use of standardized components in lighting, camera and computer technology, the customer gets an economic solution with respect to purchasing, maintenance and spare parts cost. Image data are acquired by means of newesttechnology CCD cameras. Especially in the case of glass inspection, cameras with high resolution and high sensitivity are in use. These cameras are best-suited to detect smallest defects on the material produced in great width. 由于系统的光源、摄像头和计算机技术都采用的是标准化元件，这使用户在采购、维护保养和 备件成本等方面实现经济的解决方案。利用最新的 CCD 摄像头技术获得图像数据。特别是做玻 璃检测时，使用的是具有高分辨率和高灵敏度的线扫描摄像头。这种摄像头最适合检测宽幅材 料上面的最小缺陷。

All image processing and image analysis is executed by means of PC technology incl. a frame grabber establishing the interface between camera and computer. 所有的图像处理和图像分析工作都是用计算机技术完成的,包括用将一个简单的影像撷取卡插入 计算机中作为摄像头和计算机之间的接口。 The architecture is absolutely modular with respect to lighting units and cameras. As a result, these systems will be adapted optimally to varying requirements in material width, line speed and resolution. The modular design is also valid for computer technology. A typical computer configuration uses a master PC to link the system to the periphery and to control any number of slave PCs. This design feature guarantees the free scalability of computer performance. 光源和摄像头的结构完全是积木式组件。所以，这些装置可以根据不同的材料宽度、线速度和 分辨率做最佳的配置。同时，积木式组件设计还适用于计算机技术。一个典型的计算机配置是 用一个主计算机连接检测系统与外围设备，并控制若干从计算机。这个设计特点保证了计算机 性能的自由扩展性 The core of surface inspection is our software package for defect detection and classification. To detect and classify defects, the software may chose out of a considerably feature list, which characterizes the position, size, form and gray level behavior of a defect. Defects will not only be recognized and classified. Additionally, defects are recorded, documented and stored. A precise defect map is generated, where all defects according to their position in width and length are listed. The protocol is shown graphically on the operator monitor and is updated continuously. Using standard computer network technology, the production and/or quality assurance staff may get an overview of the production at a glance. Standardized software interfaces for commercial office programs facilitate documentation and processing of the obtained data. These data offer the possibility of optimizing the production process. 表面检测的核心是我们的缺陷检测和分类软件包。为了检测和对缺陷进行分类，软件可以利用 众多的特征，它们表征了缺陷的位置、尺寸、形状和灰度等级等性能。系统对缺陷不仅仅进行 识别和分类，还做记录、形成文件并储存。然后生成一张精确的缺陷图，图上列出所有缺陷的 横纵向位置。记录以图表形式显示在操作监视器上，并不断更新。利用标准的计算机网络技术， 生产或质保人员可以一眼获得生产的全貌。与商业办公程序的标准软件接口方便将获得的数据 形成文件和处理。这些数据为优化生产工艺提供了可能性。
Ever increasing production throughput (higher speed, greater width) and ever increasing quality levels (smaller defects) make a visual inspection impossible. Automated surface inspection using newest camera and computer technology meets the requirements for 100% inspection and provides an economic solution for the customer. 不断提高的生产能力（更高的速度、更大的板宽）和质量水平（更小的缺陷）使人工检测已经 不可能满足要求。用最新的摄像头和计算机技术相结合而成的自动化表面检测可以满足 100％ 检测的要求，并为用户提供一个经济的解决方案。 Automated surface inspection produces an objective quality level, since the inspection system works always with the same set of inspection parameters, 24 hours a day, seven days a week, 365 days per year. An additional benefit is the automatic generation of a quality protocol; therefore product quality is documented and archived. Documented inspection results provide an important mean for successful processing of warranty claims. 自动化表面检测可提供一个客观的质量水平，因为检测系统始终（一天 24 小时,一周 7 天,一年 365 天）是在同样的检测参数设定下工作。它的另一个好处是可以自动生成一个质量协议，因此 可将产品质量情况文档化并归档保存。这些文档化的检测结果为顺利处理质保索赔提供一个重 要的工具。
