制药厂商为了达到药品的质量要求，结合机器视觉检测系统及自动化生产线机器，通过图形分析、颜色辨识、条形码辨识以及字符检测，以实现高质量及高效益的生产线流程。
In order to meet the quality requirements of drugs, pharmaceutical manufacturers, combined with machine vision detection system and automatic production line machines, through graphic analysis, color identification, bar code identification and character detection, to achieve high-quality and high-efficiency production line process.
近几年，各地制药厂商纷纷加入了全自动化生产线的行列。其中，液态药瓶生产制造及检测过程历经层层关卡，借助机器视觉系统，总体检测效率及检测准确性都较以往的人力大幅提高。彩色工业相机，能够在高速运转的生产线上捕捉到每个经过药瓶的图像，然后经过后端图像软件分析，进行良品与不良品筛选，同时也可以记录图像数据，以便后序可以快速且准确地查询、追溯和检索品项。
In recent years, pharmaceutical manufacturers have joined the ranks of fully automated production lines. Among them, the manufacturing and testing process of liquid medicine bottle has gone through many levels of barriers. With the help of machine vision system, the overall detection efficiency and detection accuracy are greatly improved compared with the previous manpower. The color industrial camera can capture the image of each medicine bottle passing through the high-speed production line, and then through the analysis of the back-end image software, the good and bad products can be screened. At the same time, the image data can also be recorded, so that the subsequent order can quickly and accurately query, trace and retrieve the items.
瓶装药品检测
Bottled drug testing
液态药品装瓶后，通常需要经过个检测环节，来判断药液装瓶是否够量、瓶口是否有破损、瓶盖是否压装到位，以确保药量正确、药瓶封装完好，以及瓶内的真空度正常。因此，在对瓶装药液进行检测前，制药商通常会先利用图像传感器纪录正常瓶口的特征和药液的标准位置。当每瓶药液经过检测镜头前时，相机会捕捉当前被检测物体的特征，然后将捕获的图像与先前拍摄的样本图像进行比对。检测标准采用的是相对位置标准，因此并不会因瓶子在传送带上受到微弱跳动的影响而做出错误判断。
After the liquid medicine is bottled, it usually needs to go through a test link to judge whether the liquid medicine is bottled enough, whether the bottle mouth is damaged, whether the bottle cap is pressed in place, so as to ensure that the drug quantity is correct, the medicine bottle is sealed well, and the vacuum degree in the bottle is normal. Therefore, before the detection of bottled liquid medicine, pharmaceutical manufacturers usually use image sensors to record the characteristics of the normal bottle mouth and the standard position of the liquid medicine. When each bottle of liquid medicine passes through the detection lens, the camera will capture the characteristics of the currently detected object, and then compare the captured image with the previous sample image. The detection standard adopts the relative position standard, so it will not make wrong judgment because the bottle is affected by the weak beating on the conveyor belt.
USB 工业相机在药瓶检测中的应用
Application of USB industrial camera in medicine bottle detection
USB工业相机现今已被广泛安装在机器输送带上，代替人眼进行判断和测量，因为它能够在高速移动过程中捕获清晰的图像，并能快速且准确地进行图像数据的传输和处理。USB 3．1工业相机能在较为恶劣的环境下长时间连续运行，并能保证稳定、可靠的性能和准确的拍摄效率，可以用来监控、分析和优化制药流程，确保药品质量，提高生产率。
Nowadays, USB industrial camera has been widely installed on the conveyor belt instead of human eyes to judge and measure, because it can capture clear images in the process of high-speed movement, and can transfer and process image data quickly and accurately. USB 3.1 industrial camera can run continuously for a long time under harsh environment, and can ensure stable and reliable performance and accurate shooting efficiency. It can be used to monitor, analyze and optimize pharmaceutical process, ensure drug quality and improve productivity.
瓶口瑕疵或缺损
Bottle mouth defect or defect
空药瓶在运送过程中难免会碰撞缺损，为避免瓶内有碎玻璃混进以及之后瓶盖无法密合，在填装药液之前，可运用工业相机进行垂直进行瓶口检测，首先筛选过滤有缺损或破碎瓶口的空药瓶。感光元件，提供高画速及低噪点图像品质，可清楚呈现所拍摄之瓶口，帧速率达593帧／秒，可捕捉快速通过产线的每一个药瓶，拍摄后的图像则可即时传送至小电脑，透过电脑自动比对正常样本图像之后，小电脑便可下指令至自动化机器，将不符合标准的药瓶送入废品区淘汰。
It is inevitable that the empty medicine bottle will collide and be damaged in the transportation process. In order to avoid the mixing of broken glass in the bottle and the failure of sealing the bottle cap, the industrial camera can be used for vertical detection of the bottle mouth before filling the liquid medicine. Firstly, the empty medicine bottle with defect or broken bottle mouth is screened and filtered. The photosensitive element provides high-speed and low-noise image quality, and can clearly present the captured bottle mouth. The frame rate is up to 593 frames / s, which can capture each medicine bottle passing through the production line quickly. The captured image can be immediately transmitted to a small computer. After the computer automatically compares the normal sample images, the small computer can send instructions to the automatic machine to send the unqualified medicine bottles The waste area will be eliminated.
瓶口封盖及液体位置检测
Bottle cap and liquid position detection
当药瓶经过自动化机器填充完液体药品后，便直接封口。一般医疗用药液会有内塞先封住瓶口，接著再使用机器将外盖内气压密合，以确保瓶内药液不受污染或变质。先透过相机彩色工业相机垂直拍摄瓶盖颜色，获得的图像传输至电脑，透过事先储存设定的色彩，进行颜色比对，来辨识所经过的药瓶是否正确。接着，在下一个关卡架设侧拍相机，取得的图像经过量测软件或程序来辨别液位高度，同时上下比对瓶盖位置，确认是否每个瓶盖都已密封。在此两关卡上，不合格的药瓶则如瓶口检测后的结果，由小计算机自动下指令至自动化机器，送至废品区。
When the medicine bottle is filled with liquid medicine by automatic machine, it is sealed directly. In general, the bottle mouth is sealed with an inner plug, and then the air pressure inside the cover is sealed with a machine to ensure that the liquid medicine in the bottle is not polluted or deteriorated. First, the color of the bottle cap is photographed vertically by the color industrial camera of the camera, and the image is transmitted to the computer. By storing the set color in advance, the color comparison is carried out to identify whether the medicine bottle passed by is correct. Then, a side camera is set up at the next level, and the obtained image is identified by measuring software or program. At the same time, the position of bottle cap is compared up and down to confirm whether each cap is sealed. At these two levels, unqualified medicine bottles, such as the results of bottle mouth detection, are automatically sent to the automatic machine by the small computer and sent to the waste area.
贴标／标码检测及字符辨识
Label / code detection and character recognition
而除了药瓶检测，许多制药商会在药瓶瓶身或瓶盖上贴上或嵌入卷标号码、日期或相关的药品名称。映美精相机提供高效稳健的条形码辨识算法，能迅速地侦测并辨识任何方位的一维与二维条形码；也可以设定只扫描特定的条形码图形及方位；或设定感兴趣区域ROI，以加速侦测及解码效率。制药厂商只需要利用工业相机读取标签上或喷涂在包装上的一维或二维条形码，就可以实时获得药品的详细成分、生产日期、批号和有效日期等相关信息。
In addition to bottle testing, many pharmacists attach or embed the label number, date or related drug name on the bottle body or cap. Yingmei precision camera provides an efficient and robust barcode identification algorithm, which can quickly detect and identify one-dimensional and two-dimensional barcodes in any direction; it can also set to scan only specific barcode graphics and orientation; or set ROI to accelerate detection and decoding efficiency. Pharmaceutical manufacturers only need to read the one-dimensional or two-dimensional barcode on the label or sprayed on the package by using industrial camera to obtain the detailed information of drug ingredients, production date, batch number and expiration date in real time.
机器视觉检测系统在药瓶检测的部分应用中确实在很大程度上提高了制药的工作效率和准确度，对于制药厂家而言，充分解决了人工检测不能完成的部分，在机器视觉系统的帮助下，药瓶检测效率及检测准确性都较以往大幅提升。
The machine vision detection system in some applications of drug bottle detection really greatly improves the efficiency and accuracy of pharmaceutical. For pharmaceutical manufacturers, it fully solves the part that cannot be completed by manual detection. With the help of machine vision system, the efficiency and accuracy of drug bottle detection are greatly improved.
