摘要 現(xiàn)今從占有大量鏡片市場的玻璃鏡片向樹脂鏡片的轉(zhuǎn)變成為我國現(xiàn)今對鏡片需求和生產(chǎn)的主要方向。作為一個在國際上具有很強國際競爭力的人口大國，隨著國內(nèi)技術(shù)的日益成熟，我國并不僅僅滿足于鏡片的進(jìn)口。鏡片的性能在不斷的提升，并且因為人口多勞動力較為低廉，因此在價格方面具有很大的優(yōu)勢。從整個鏡片市場來看，由于娛樂設(shè)施的增加和對電腦電視手機的依賴性越來越強，視力下降更快已經(jīng)成為當(dāng)代人普遍存在的問題，整個鏡片行業(yè)的發(fā)展也是不容小視存在巨大潛力的。但是由于鏡片的制造過程中容易產(chǎn)生一些瑕疵缺陷，因此樹脂鏡片的瑕疵檢測也變得越來越重要。
本論文首先介紹了樹脂鏡片的產(chǎn)生與發(fā)展，接著討論了樹脂鏡片檢測時的光源選擇以及照明方案，搭建檢測總體平臺，進(jìn)行圖像采集，最后對瑕疵進(jìn)行分類以及分析。
根據(jù)圖像的結(jié)果顯示，我們可以發(fā)現(xiàn)利用LED環(huán)形光源檢測樹脂鏡片的點雜質(zhì)、羽毛、氣泡、羽毛、加硬點五種瑕疵缺陷是切實可行的，而LED環(huán)形光源照明方案無法檢測出的樹脂鏡片的膜脫落瑕疵缺陷我們可以利用球積分光源照明方案彌補。因此利用這兩種照明方案便可以檢測出樹脂鏡片常見的六種瑕疵缺陷。
通過本次實驗，我們可以進(jìn)行了兩種照明實驗方案的設(shè)計，利用其各自的優(yōu)勢可以很好的檢測出樹脂鏡片常見的六種瑕疵缺陷。具有很強的操作性和可行性，為樹脂鏡片的瑕疵缺陷注入了新的血液。

Study Of The Lighting-mode Experiment On Detecting The Defects Of Resin Lenses Using Image Acquisition System

Abstract Science and technology are constantly moving forward, from the possession of a large glass lens to lens market transition resin lens become the main direction of the lens of today's demand and production. As a populous country with strong international competitiveness in the international arena, with the growing maturity of domestic technology, China's imports are not only satisfied with the lens. Lens performance constantly upgrading, and because relatively low population and labor force, and therefore has a great advantage in terms of price. From the entire lens market, due to increased recreational facilities and TV mobile phone dependence on computers more powerful, faster and decreased vision has become a widespread problem of contemporary people, the development of the industry is not to be overlooked lens there is a huge potential . However, due to the lens manufacturing process prone to some flaws defects, defect detection resin lenses therefore becoming increasingly important.
This paper first introduces the origin and development of resin lens, then discussed the resin lens detection and lighting scheme, the choice of light source in the overall platform building detection, image acquisition, finally, the defects are classified and analyzed.
According to the result of image display, we can find that using the LED ring light source detection point of resin lens, feathers, feathers, bubbles, impurities and hard point of five kinds of flaw defects is feasible, and LED ring light source lighting solution cannot detect resin lens membrane peeling defects defects we can use the ball of integral lighting solutions. So take advantage of the two kinds of lighting scheme can detect the resin lens six kinds of defects of common defects.
Through this experiment, we can make the two kinds of experimental project of lighting design, using its own advantage can well detect the resin lens six kinds of defects of common defects. Have strong operability and feasibility for the drawbacks of resin lens defect injected new blood.
Keywords:resin lens defect detection lighting design
