摘要
多目视觉检测技术是通过多个CCD传感器,从不同角度获取同一目标的不同角度的图像,并对多幅图像进行匹配、分割、相减等处理技术获取目标信息的一种图像处理技术.多目视觉检测技术能够比单目视觉检测技术获得更多的图像信息,这就降低了后继处理的复杂程度,提高检测系统的测量精度、抗干扰能力以及测量效率.然而,由于需要获得不同的图像信息,这就使得它对图像的质量,照明系统和照明方式的要求比单目视觉系统的要求更高.根据实验要求,主要设计了多目视觉检测技术中的照明系统,实现了平行光照明技术在多目视觉检测中的应用,并搭建实验平台完成实验.验证了光源的种类、光源的照明结构、照明方式以及被测物体的光学特性、背景特性等是影响多目视觉检测的重要因素,为该技术的应用、推广提供了实验依据.
Multi vision detection is an image processing technology which captures images of the goal from different angles with several CCD sensors, and obtains the information of the image after matching, segmentation and minus. The multi vision detection technology can obtain more information of the image than monocular vision, which reduces the complexity of follow-up treatment and improves the measurement accuracy of detection systems as well as the anti-interference ability and measurement efficiency. However, in order to obtain images with different information, it requires better image and lighting systems than monocular vision system. Based on the requirements of the experiment, the lighting system of multi vision detection is designed, and the experiment platform is set up. It is confirmed that the type of light source, the structure of lighting, the optical properties of detected objects, and the background characteristics are important factors for visual inspection technology, and the research provides the experimental basis for the promotion.
