基于图像处理的药片计数系统设计

Design of tablet count system based on image processing

为了实现对动态药片计数的需求,提出了一种基于图像处理的方法。应用数字图像处理的知识,包括:灰度化、图像增强、滤波、阈值分割等,对实时图像进行处理,提取出药品的轮廓形状。在此基础上,通过研究视频检测计数方法,使用虚拟线圈法,开发出一种可靠的动态计数算法,并在Windows操作系统上,使用MATLAB/GUI完成软件设计。通过实验,证实通过视频处理技术和本文设计的算法,能较好的完成药片的计数。

In order to satisfy the requirement of tablet count and defect detection ,a method which is based on image processing is proposed. Apply the knowledge of digital image processing, including ：grayscale, image enhancement, filtering, threshold segmentation, process the real-time image, extracting the contour shape of the drugs. On this basis, by studying video detection counting method, by use the virtual coil method developed a reliable the dynamic count and defect detection algorithms, and based on the windows operating system, complete software development by using MATLAB/GUI. By experiment, it is confirmed that through the video processing technology and the algorithm in this article can complete the tablet count and defect detection.
