1、什么是機(jī)器視覺？

1. What is machine vision?

機(jī)器視覺就是用機(jī)器代替人眼來做測(cè)量和判斷。視覺檢測(cè)系統(tǒng)是指通過機(jī)器視覺產(chǎn)品（即圖像攝取裝置，分 CMOS 和CCD 兩種）將被攝取目標(biāo)轉(zhuǎn)換成圖像信號(hào)，傳送給專用的圖像處理系統(tǒng)，得到被攝目標(biāo)的形態(tài)信息，根據(jù)像素分布和亮度、顏色等信息，轉(zhuǎn)變成數(shù)字化信號(hào)；圖像系統(tǒng)對(duì)這些信號(hào)進(jìn)行各種運(yùn)算來抽取目標(biāo)的特征，進(jìn)而根據(jù)判別的結(jié)果來控制現(xiàn)場(chǎng)的設(shè)備動(dòng)作。

Machine vision is to use machines instead of human eyes to measure and judge. Machine vision system is to point to by machine vision products (namely image extraction device, CMOS and CCD two) will be taking the target into image signal, and send it to the dedicated image processing system, get the subject target shape information, according to the pixel distribution and brightness, color and other information, converted to digital signal; The image system takes the characteristics of the target by performing various operations on these signals, and then controls the device action on the scene according to the discriminant result.

機(jī)器視覺可以用來做什么？

What can machine vision do?

機(jī)器視覺系統(tǒng)可以快速獲取大量信息，而且易于自動(dòng)處理，也易于同設(shè)計(jì)信息以及加工控制信息集成，因此，在現(xiàn)代自動(dòng)化生產(chǎn)過程中，人們將機(jī)器視覺系統(tǒng)廣泛地用于工況監(jiān)視、成品檢驗(yàn)和質(zhì)量控制等領(lǐng)域。

Machine vision system can quickly obtain a large amount of information, and easy to automatic processing, also easy to design information and process control information integration, therefore, in modern automated production process, people will be widely used in machine vision system condition monitoring, inspection and quality control, etc

機(jī)器視覺檢測(cè)系統(tǒng)的特點(diǎn)是提高生產(chǎn)的柔性和自動(dòng)化程度。在一些不適合于人工作業(yè)的危險(xiǎn)工作環(huán)境或人工視覺難以滿足要求的場(chǎng)合，常用機(jī)器視覺來替代人工視覺；同時(shí)在大批量工業(yè)生產(chǎn)過程中，用人工視覺檢查產(chǎn)品質(zhì)量效率低且精度不高，用機(jī)器視覺檢測(cè)方法可以大大提高生產(chǎn)效率和生產(chǎn)的自動(dòng)化程度。

Machine vision detection system is characterized by improving the flexibility and automation of production. Machine vision is used to replace artificial vision in situations where the work environment or artificial vision is not suitable for manual work. At the same time in the process of mass industrial production, with artificial visual inspection product quality is not high, low efficiency and precision in machine vision detection method can greatly improve the production efficiency and automation of production.

機(jī)器視覺易于實(shí)現(xiàn)信息集成，是實(shí)現(xiàn)計(jì)算機(jī)集成制造的基礎(chǔ)技術(shù)。機(jī)器視覺工業(yè)檢測(cè)系統(tǒng)就其檢測(cè)性質(zhì)和應(yīng)用范圍而言，分為定量和定性檢測(cè)兩大類，每類又分為不同的子類。

Machine vision is easy to realize information integration and is the basic technology of computer integrated manufacturing. The machine vision industrial testing system is divided into two categories: quantitative and qualitative, which are divided into different subcategories.

機(jī)器視覺在工業(yè)在線檢測(cè)的各個(gè)應(yīng)用領(lǐng)域十分活躍，如：印刷電路板的視覺檢查、鋼板表面的自動(dòng)探傷、大型工件平行度和垂直度測(cè)量、容器容積或雜質(zhì)檢測(cè)、機(jī)械零件的自動(dòng)識(shí)別分類和幾何尺寸測(cè)量等。

Machine vision in the industrial on-line detection of each application field is very active, such as: PCB visual inspection, on the surface of the steel plate automatic detection, parallelism and perpendicularity on large-sized workpiece measurement, container volume or impurity detection, automatic identification classification of mechanical parts and geometry size measurements.

此外，在許多其它方法難以檢測(cè)的場(chǎng)合，利用視覺檢測(cè)設(shè)備可以有效地實(shí)現(xiàn)。機(jī)器視覺的應(yīng)用正越來越多地代替人去完成許多工作，這無疑在很大程度上提高了生產(chǎn)自動(dòng)化水平和檢測(cè)系統(tǒng)的智能水平。
