class="title">詳細說明</p><div id="cmelnpw" class="box"><p><p style="text-indent:25px">對于工件的測量無非有兩個重要步驟，即測量儀器的選擇和測量方法的應(yīng)用，高精度二次元測量儀生產(chǎn)工藝。在工件測量中，難測量的工件非易變形工件莫屬，尤其是經(jīng)過微加工的精密零件的測量，這一直以來都是一個難題。光學(xué)測量系統(tǒng)具有測量速度快、不會引起零件變形等有點，但其也有一定局限性，如工件的可見邊緣往往無法反映其后被遮擋部分的情況，光學(xué)測量系統(tǒng)通常不能確定諸如平行度、垂直度、圓柱度、平面度等三維形狀位置精度等。復(fù)合式影像測量儀支持復(fù)合傳感系統(tǒng)：光學(xué)傳感器、觸發(fā)式測頭和掃描測頭，高精度二次元測量儀生產(chǎn)工藝,TTL激光和具有創(chuàng)新意義的白光傳感器，高精度二次元測量儀生產(chǎn)工藝。復(fù)合式影像測量儀可以完成在一次安裝中對復(fù)雜零件的所有關(guān)鍵參數(shù)的測量。光學(xué)傳感器無需接觸那些精密的被測特征，避免采用機械接觸而引起的變形。測量儀具有高速與較準的特性。高精度二次元測量儀生產(chǎn)工藝</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="高精度二次元測量儀生產(chǎn)工藝,測量儀" src="https://tyunfile.71360.com/UploadFile/ytjm168/637394816306118100/6754299.png"></div><p style="text-indent:25px">影像測量儀的分辨率和對比度是影響成像質(zhì)量的重要因素，測量儀的分辨率指影像系統(tǒng)所能重現(xiàn)的被測物體細節(jié)的數(shù)量，對比度則是影像系統(tǒng)所產(chǎn)生的被測物體與其背景之間的灰度差別。而決定分辨率和對比度的重要因素則是：燈光、鏡頭和攝像頭。影像儀所需小圖素分辨率可由下式計算：小分辨率=（對象長端長度/小特征尺寸）×2 。以條形碼為例，假如長端長度為100mm，小特征尺寸是0.2mm，那么根據(jù)上式可算出其小分辨率應(yīng)該是（100/0.2）×2=1000 。鏡頭焦距是分辨率另一種表現(xiàn)形式，視野（FOV）指物體長端長度，工作距離（WD）是物體到鏡頭的距離，探頭大小是攝像探頭的尺寸，以mm表示。上述幾項有如下關(guān)系：焦距=S×（WD/FOV）。失真是另一個影響光學(xué)影像儀成像質(zhì)量的因素，指的是因儀器鏡頭光學(xué)誤差引起幾何偏差，從而在影像平面上造成物體錯位，在計算時可以把測量失真考慮進去。高精度二次元測量儀生產(chǎn)工藝一鍵式影像測量儀的重要硬件是由上下光源、高像素 CCD 相機、大視角大景深遠心鏡頭及固定載物臺組成。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="高精度二次元測量儀生產(chǎn)工藝,測量儀"

style="text-indent:25px">在使用影像測量儀時，將點、線、圓、弧等這一類的元素稱為特征。特征又分為二維特征和三維特征，二維特征指的是點、線、圓等平面特征，是可以用影像來測量的元素；三維特征指的是面、球、圓柱、圓錐等一類立體特征，通常是用探針測量的。這里有一個特殊的，平面，既可以用影像測量也可以用探針，用影像的方法就是使用對焦點，在平面上選取三個點以上構(gòu)造平面，用探針就是直接選取平面即可。測量要素在影像測量過程中是很重要的一步，特征選取正確了，后面的測量結(jié)果才會是準確的。</p><p style="text-indent:25px">單點測量采用單點觸測方式由于得到的是一些離散的點，所以采用二乘法進行計算和評價。采用二乘法進行計算時，采樣點一般為偶數(shù)，且平均分布。在用單點法進行圓度測量時，采樣點數(shù)不能太少，否則反應(yīng)不了圓度的真實情況，一般要達到16 點以后即可反映被測圓的基本輪廓形狀，如果為了掌握更嚴密的形狀，可適當(dāng)增加測量點數(shù)，如24，32 等。采樣時一般采用自動測量，因為手動采樣不便控制矢量方向。單點觸測方式的特點是測量效率高，對測球的磨損小。實測結(jié)果表明，不論是單點測量還是掃描測量，測量儀都可以得到過與圓度儀十分接近的結(jié)果，說明三坐標測量儀測量圓度具有很高的精度。但是，由于三坐標測量儀一般都采用球形測頭，球形測頭對臟物比較敏感，容易造成虛假測量，而圓度儀采用的是斧形測頭，能夠穿過臟物，因此臟物對它的影響較小。所以使用三坐標測量儀時要注意對工件的清潔。測量儀的日常保護保養(yǎng)十分重要。</p><div

style="text-indent:25px">測量儀器是為了取得目標物某些屬性值而進行衡量所需要的第三方標準，測量儀器一般都具有刻度，容積等單位。測量儀器的概念其基本內(nèi)容包括：精度、誤差、測量標準器材、長度測量、角度測量、形狀測量、傳統(tǒng)光學(xué)儀器。在精密測量上的應(yīng)用等等。測量儀器有接觸試和光學(xué)試測量兩種（用的多）接觸試：一般測量工具和3D測量工具（三坐標測量機又叫三次元）三坐標測量機又叫三次元，它可以測量很多復(fù)雜的空間尺寸：如模具和汽車產(chǎn)品。電子測量儀器具有獨特的關(guān)聯(lián)戰(zhàn)略性產(chǎn)業(yè)，它自身的發(fā)展好壞，對整個國民經(jīng)濟特別是電子信息產(chǎn)業(yè)的發(fā)展有著十分明顯的影響。我國的電子測量儀器市場龐大，需求量大，電子測量儀器對電子信息產(chǎn)業(yè)的發(fā)展起到至關(guān)重要的作用。光學(xué)影像儀主要有兩種測量形式，分別是表面測量、輪廓測量。高精度二次元測量儀生產(chǎn)工藝</p><p

style="text-indent:25px">長度測量的基本內(nèi)容可以知道，長度計量就是要將測量值同被測量的真值進行對比，并將對比的結(jié)果作為被測量對象的量值來進行實驗的一個過程。通常而言在具體長度測量中，操作的基礎(chǔ)是被測量物的基面，主要是由點和線共同構(gòu)成的。在具體的長度測量實踐中，件事情就是要明確測量的基面，只有在做好基面工作的基礎(chǔ)上才能進行它同另一面距離的測量。接下來需要考慮的就是測量工件如何完成定位的問題，要保證工件的位置能夠很好的完成測量，不能增加測量的難度，要在簡單的方式下提高測量的較準度。高精度二次元測量儀生產(chǎn)工藝</p><p
