食品在裝運前必須要進行最後一道檢測工序， 稱之為終檢， 以確保它們的蓋子上印有有效期代碼、罐體上貼有正確的標籤且具有防偽印章。 過去， 食品盒的檢測是由人工手動完成的。 這是一個容易出現人為錯誤且耗時的過程。 為了降低手工檢測的成本並提高效率， 目前很多大型食品生產企業的食品盒產品檢測是用的基於機器視覺的視覺檢測設備。
The final inspection process must be carried out before shipment, which is called final inspection to ensure that their lid is printed with valid code, a correct label on the tank and a anti-counterfeit seal on the tank. In the past, the detection of food boxes was done manually. This is a process prone to human errors and time consuming. In order to reduce the cost of manual detection and improve the efficiency, the detection of food box products in many large food production enterprises is a visual inspection device based on machine vision.
在實際檢測過程中， 裝有特定食品的食品盒通過傳送帶被輸送到該視覺檢測系統中。 一旦食品盒進入該視覺檢測系統， 光反射感測器即被觸發。 隨後， 安裝在傳送帶上的編碼器， 開始跟蹤食品盒的位置資訊， 直到食品盒到達系統中的一個最佳位置。 在這個最佳位置處， CCD工業相機被觸發， 用於捕獲食品盒外部的360°視圖以及食品盒蓋子的圖像。 以檢測是否遺漏標籤， 防偽印章和日期代碼。
In the actual detection process, food boxes containing specific foods are conveyed to the visual inspection system through the conveyor belt. Once the food box enters the visual inspection system, the light reflection sensor is triggered. Subsequently, the encoder installed on the conveyor belt starts tracking the location information of the food box until the food box reaches the best position in the system. At this best location, the CCD industrial camera is triggered to capture the image of the 360 degree view outside the food box and the lid of the food box. To check whether the labels, forgery stamps and date codes are missing.
一旦視覺檢測系統被觸發， 相機開始捕獲資料， 將這些資料傳送給PC,PC中的機器視覺檢測軟體將處理分析這些圖像， 如果發現了有缺陷的食品盒， 則將啟動氣動剔除系統， 將有缺陷的食品盒從檢測線中移走， 視覺檢測設備認為檢驗到了一個不合格的產品， 這樣子迴圈下去， 大幅度提高了企業的生產效率， 降低了人工成本。
Once the visual detection system is triggered, the camera begins to capture the data and sends the data to the PC. The machine vision testing software in PC will process and analyze the images. If the defective food box is found, the pneumatic removal system will be started, the defective food box is removed from the detection line and the visual inspection equipment is considered to be examined. An unqualified product has been detected, which has greatly improved the production efficiency of enterprises and reduced the labor cost.
