奶制品需求量的增加，奶制品行業的規模化、標準化、機械化、組織化水平大幅提升，質量監管不斷加強，機器視覺OCR字符視覺檢測系統為保障奶制品的品質上作出了積極貢獻。
With the increasing demand for dairy products, the scale, standardization, mechanization and organization of dairy industry have been greatly improved, and the quality supervision has been strengthened. The OCR character visual inspection system of machine vision has made positive contributions to the quality of dairy products.
機器OCR字符視覺檢測系統檢測牛奶包裝噴碼字符，當檢測到牛奶包裝噴碼有字符錯誤的情況時，系統發送信號給報警裝置進行報警或停機處理。
The machine OCR character vision detection system detects the spray code characters of milk packaging. When it detects that there is a character error in the spray code of milk packaging, the system sends a signal to the alarm device for alarm or shutdown processing.
工作流程：
Workflow:
1.在牛奶自動化包裝生產線上安裝OCR字符檢測系統；
OCR character detection system is installed in the milk automatic packaging production line;
2.包裝上進行噴碼后進入視覺檢測工位時，通過觸發機器視覺傳感器拍攝牛奶包裝頂部三期噴碼圖片送入系統，自動化檢測系統對圖片進行提取分析并和設定的良品字符圖像特征做比對；
When entering the visual inspection station after code spraying on the package, the machine vision sensor was triggered to shoot the three-phase spray code pictures on the top of milk packaging and sent them to the system. The automatic detection system extracted and analyzed the pictures and compared them with the set character image features of good products;
3.當視覺系統檢測到牛奶包裝噴碼不合格時，系統發出信號到剔除裝置給予剔除處理及報警提示。
When the vision system detects that the milk packaging spray code is unqualified, the system sends a signal to the rejection device to give rejection processing and alarm prompt.
測試條件
Test conditions
產品測試時，視場有一定的容忍空間，但是并不意味著目標可以在視場里任意出現，至少需要保證檢測特征全部出現在視場內且有一定包容空間，以便于尋找特征。可以根據具體的要求設置相應的視覺大小，選擇合適分辨率的相機，然后識別噴碼。根據要求，我們將視野設置為150*120mm。鏡頭的工作距離設置為350mm，光源的距離設置為280mm，這樣可以有比較大的工作空間。
In product testing, there is a certain tolerance space in the field of view, but it does not mean that the target can appear arbitrarily in the field of view. At least, it is necessary to ensure that all detection features appear in the field of view and have a certain tolerance space, so as to find features easily. We can set the corresponding visual size according to the specific requirements, select the appropriate resolution camera, and then recognize the spray code. According to the requirements, we set the field of vision to 150 * 120mm. The working distance of the lens is set to 350mm, and the distance of the light source is set to 280mm, so that there is a larger working space.

牛奶生產線應用OCR字符視覺檢測系統，不僅可以快速對牛奶包裝日期噴碼進行檢測，還能及時剔除日期噴碼不合格產品，在提高生產效率和檢測精度的同時，大幅節約了人工成本。
The application of OCR character visual inspection system in milk production line can not only quickly detect the date spray code of milk packaging, but also timely eliminate the unqualified products with date spray code, which can improve the production efficiency and detection accuracy, and greatly save the labor cost.
人工檢測生產日期噴碼缺陷勞動強度大、智能化水平低、效率低等問題，OCR字符視覺檢測系統實現了對牛奶制品生產日期缺碼、模糊碼等缺陷檢測，達到預期的檢測效果。
Manual detection of production date spray code defects, labor intensity, low level of intelligence, low efficiency, OCR character visual inspection system to achieve the desired detection results of milk products production date missing code, fuzzy code and other defects detection.
