視覺測量精度能達到多少是判斷一個視覺檢測系統技術成功與否的關鍵因素。在視覺檢測系統技術測量項目中，很多客戶會遇到一些因為檢測精度不夠而造成的困擾。如何判斷出機器視覺檢測技術測量精度的多少呢？
The accuracy of vision measurement is the key factor to judge whether a visual inspection system is successful or not. In the technical measurement project of visual inspection system, many customers will encounter some problems caused by insufficient detection accuracy. How to judge the accuracy of machine vision inspection technology?
視覺檢測系統在完成設計之后，都要進行測試，才能確定能不能檢這個與你要檢測的零件尺寸大小，與所使用的相機解析率，以及軟件的算法能達到的精度。你能將需要檢測的東西成像清楚，需要檢測的邊界有正確明顯的色差才有可能實現。
After the completion of the design of the visual inspection system, it is necessary to test to determine whether it can check the size of the parts you want to detect, the resolution rate of the camera used, and the accuracy of the software algorithm. You can image things that need to be detected clearly. Only when the boundary needs to be detected has correct and obvious color difference, can it be realized.
例如：檢測加工零件的外形尺寸、內外徑，要求精度到10um。目前很多配置選擇500萬的相機，理論上是可以達到10um的精度的。可實際客戶測試的精度遠遠達不到10um的要求，能做到30um就很不錯了。
For example: to detect the overall dimension, inside and outside diameter of machining parts, the accuracy is required to be 10um. At present, many configurations choose 5 million cameras, which can theoretically reach the accuracy of 10um. But the accuracy of the actual customer test is far less than the requirement of 10um, it is very good to be able to do 30um.
要檢測的零件尺寸大小，與所使用的相機分辨率，以及軟件的算法能達到的精度都有關系，當然，首先是你能將需要檢測的東西成像清楚，需要檢測的邊界有正確明顯的色差才有可能實現。
The size of the parts to be tested is related to the resolution of the camera used and the accuracy of the software algorithm. Of course, the first thing is that you can clearly image what needs to be detected, and the boundary that needs to be detected has correct and obvious color difference.
一般來說，零件在圖像中的視野越大，相機的分辨率越高以及檢測到的邊界越清晰，檢測精度越高。在產品視野合適，拍攝效果好的情況下，紅寶自動化視覺檢測系統檢測工件尺寸的精度可達一絲以內。
Generally speaking, the larger the field of view of the part in the image, the higher the resolution of the camera and the clearer the detected boundary, the higher the detection accuracy. When the product vision is suitable and the shooting effect is good, the accuracy of Hongbao automatic visual inspection system to detect the workpiece size can reach less than one trace.
基于機器視覺檢測系統技術的檢測系統具有成本低、精度高、安裝簡易等優點。再加上功能強大的視覺軟件，易于調整，靈活方便，且測量數據可存儲，便于建立統計分析，便于快速發現問題，解決問題，是行業檢測技術的不二之選。
The detection system based on machine vision technology has the advantages of low cost, high precision and easy installation. Combined with powerful visual software, it is easy to adjust, flexible and convenient, and the measurement data can be stored, which is convenient to establish statistical analysis, to quickly find problems and solve problems, which is the best choice of industry detection technology.
