                                                                                                                                                                如今,機器視覺檢測技術廣泛應用于工廠產品檢測,大大提高了尺寸測量、外觀缺陷檢測、字符識別和定位等生產的自動化程度。

                                                                                                                                                              康耐視視覺檢測

                                                                                                                                                                OCR字符檢測是指對刻在零件或產品上的字符進行確認、識別和判斷的檢測。比如在生產線上的機器視覺檢測設備上安裝ocr/ocv字符識別系統,利用ocr字符檢測系統檢測印刷的生產日期,如漏碼、漏字、數據錯誤等。系統向報警裝置發送信號。

                                                                                                                                                                該系統的工作過程如下:

                                                                                                                                                                圖像采集-圖像預處理-字符分割-字符讀取-圖像最終處理。

                                                                                                                                                                通過工業攝像機和工業鏡頭采集字符圖像,通過機器視覺軟件進行處理和分析,判斷被檢產品是否合格,并輸出檢測結果和相應的信號。

                                                                                                                                                                可檢測項目包括漏印、對錯、缺陷、有無、偏移等。

                                                                                                                                                                機器OCR字符檢測在食品生產數據中的應用只是其工業應用的九牛一毛,如半導體芯片上的字符和條形碼,PCB板上的字符二維碼,食品、飲料、藥品和消費品包裝上的文字、標簽和條形碼,汽車制造業的零件刻字碼,制造業和醫藥行業的產品編號、批號、保質期等字符信息,電子電容絲網印刷檢測等。

                                                                                                                                                                包裝上的文字信息是產品的“身份證”,是產品可追溯和管理的憑證,必須清晰準確。為了快速識別、讀取和記錄產品的字符信息,機器視覺檢測技術非常重要。
