生產制造行業的自動化發展，使得生產效率迅速提高，在保障產品質量的同時，也要保障產品外觀的完整、合格以及美觀性。視覺檢測系統便應運而生，視覺檢測系統可以檢測什么呢？
With the development of automation in manufacturing industry, the production efficiency has been improved rapidly. At the same time, the integrity, qualification and aesthetics of product appearance should be guaranteed. Visual inspection system came into being. What can visual inspection system detect?
視覺檢測系統技術就是通過“視覺”來處理信息并且反饋的過程，包括圖像增強、數據編碼和傳輸、平滑、邊緣銳化、分割、特征抽取、圖像識別與理解等內容。經過這些處理后，輸出圖像的質量得到相當程度的改善，既改善了圖像的視覺效果，又便于計算機對圖像進行分析、處理和識別。
Visual inspection system technology is a process of information processing and feedback through "vision", including image enhancement, data coding and transmission, smoothing, edge sharpening, segmentation, feature extraction, image recognition and understanding. After these processing, the quality of the output image is improved to a certain extent, which not only improves the visual effect of the image, but also facilitates the computer to analyze, process and identify the image.
人工檢測效率是在一個固定區間，無法大幅提升，而在流水線重復且機械化的檢測過程中，檢測人員很容易出現疲勞而導致檢測效率降低；而機器視覺檢測設備能夠更快的檢測產品，特別是在生產線檢測高速運動的物體時，機器能夠提高檢測效率。
The efficiency of manual detection is in a fixed range, which can not be greatly improved. In the repeated and mechanized inspection process of the assembly line, it is easy for the inspectors to fatigue and reduce the detection efficiency; while the machine vision detection equipment can detect products faster, especially in the production line to detect high-speed moving objects, the machine can improve the detection efficiency.
由于人眼有物理條件的限制，即便是依靠放大鏡或顯微鏡來檢測產品，也會受到主觀性方面的影響，精度無法得到保證，而且不同的檢測人員的標準也會存在有差異；在精確性上機器有明顯的優點，它的精度能夠達到千分之一英寸。而且機器視覺檢測設備不受主觀控制，只要參數設置沒有差異，相同配置的多臺機器均能保持相同精度。
Due to the physical conditions of the human eye, even if we rely on a magnifying glass or a microscope to detect products, it will be affected by subjectivity, and the accuracy can not be guaranteed, and the standards of different inspectors will also have differences; in terms of accuracy, the machine has obvious advantages, and its accuracy can reach one thousandth of an inch. Moreover, machine vision inspection equipment is not subject to subjective control. As long as there is no difference in parameter settings, multiple machines with the same configuration can maintain the same accuracy.
視覺檢測系統技術的逐漸完善，已經代替人工檢測。要知道對于工廠而言，最重要的是“受控”，我們可以接受有個別特殊的未發生過的缺陷被漏出，但必須知道有一些經常發生的不可接受的缺陷一定能夠被發現。
With the gradual improvement of visual inspection system technology, it has replaced manual detection. We should know that the most important thing for the factory is "controlled". We can accept that some special defects have not occurred, but we must know that some frequently occurring unacceptable defects can be found.
視覺檢測系統短期內不能完全取代人工目檢，主要原因是還不夠智能，中小企業愿意投資的意愿不強。但是對于工廠的質量控制來講，機器視覺檢測比人工檢測更可靠。
Visual inspection system can not completely replace manual visual inspection in the short term, the main reason is that it is not intelligent enough, and small and medium-sized enterprises are not willing to invest. But for the factory quality control, machine vision inspection is more reliable than manual inspection.
