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，廣東測量儀管用嗎，小特征尺寸是0.2mm，那么根據(jù)上式可算出其小分辨率應該是（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。上述幾項有如下關系：焦距=S×（WD/FOV）。失真是另一個影響光學影像儀成像質(zhì)量的因素，指的是因儀器鏡頭光學誤差引起幾何偏差，廣東測量儀管用嗎，廣東測量儀管用嗎，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。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。廣東測量儀管用嗎</p><div

style="text-indent:25px"> 一鍵式影像測量儀的優(yōu)點：測量速度極快，能在 2 到 5 秒內(nèi)完成 100 個以內(nèi)的尺寸的測量及公差的評價.重復測量精度高，解決了同一個產(chǎn)品反復測量數(shù)據(jù)一致性差的現(xiàn)象。.儀器結(jié)構(gòu)簡單，由于不需要光柵尺量具，儀器運行的穩(wěn)定性能好。由于精度標尺是 CCD 相機的像素點，而像素點是不會隨時間變化，也不會受到溫濕度的影響，所以儀器的精度比較穩(wěn)定，且可以通過軟件實現(xiàn)測量精度自動校準。一鍵式測量儀可加設移動平臺,可完美解決傳統(tǒng)一鍵式測量儀測量行程小的問題。一鍵式影像測量儀應用在精密螺絲、量具、精密彈簧、齒輪、手機外殼、手機玻璃、精密五金配件等尺寸較小的產(chǎn)品及零部件的批量快速測量上。半自動影像測量儀-3020MZ哪家優(yōu)惠電子測量儀器對電子信息產(chǎn)業(yè)的發(fā)展起到至關重要的作用。</p><div

style="text-indent:25px">用游標卡尺、外徑千分尺等測量出的值是數(shù)據(jù)，是一種測量。而將數(shù)據(jù)與標準值相比較，得到的差值就是相對數(shù)據(jù)，屬于相對測量。在產(chǎn)品生產(chǎn)加工過程中的測量，屬于主動測量?？梢詼p少殘次品和廢品的數(shù)量，提高產(chǎn)品質(zhì)量。而產(chǎn)品完工后再進行的測量，屬于被動測量。此時的測量只能用來篩選不合格的產(chǎn)品，相比于主動測量就沒有那么多優(yōu)勢。單項測量與綜合測量就容易區(qū)分，單項測量就是測量工件的某一數(shù)據(jù)，這個數(shù)據(jù)與其他參數(shù)沒有聯(lián)系。而綜合測量就是測量工件的多個單項數(shù)據(jù)，這些數(shù)據(jù)相互聯(lián)系起來，形成綜合測量。量具按照用途可以分為三種：通用（都能）量具、**量具、標準量具。通用量具一般有卡尺、直尺、平板、角度尺等**量具就是針對一些檢測工件而設計的。過去工廠選用測量工具大都沒有一個標準，基本靠經(jīng)驗來選擇。而量具對測量誤差有很大的影響，占誤差比率的1/3~/10，甚至有一些占到1/2。而量具的選擇沒有統(tǒng)一標準就減少了測量結(jié)果的可比性。合理的選擇測量器具對影像測量儀的測量非常重要。選擇測量器具要考慮：測量器具要與被測工件相匹配；保證測量精度；被測工件的大小、形狀、尺寸、數(shù)量等；工廠的生產(chǎn)成本、生產(chǎn)方式等。</p><p style="text-indent:25px">如果出現(xiàn)儀器運轉(zhuǎn)接觸不良或暫止不靈的情況，可以關掉儀器，重新插好電源開關等，或輕敲儀器故障部位，之后再重啟。重啟之后看儀器能否正常運轉(zhuǎn)，如果可以，說明儀器某些地方接觸不良或者電源出接觸不良。因季節(jié)原因，溫度有時會過高或過低，這些都有可能對儀器有影響。若儀器故障后關閉，過一段時間重啟，正常工作一段時間后又出故障。重復出現(xiàn)這種現(xiàn)象，可能是儀器某個部件由于工作中溫度提高，而不能正常使用?？梢允褂脽o水酒精將其降溫。而對于溫度過低就可以調(diào)節(jié)室內(nèi)工作環(huán)境溫度。二次元又稱影像儀，影像測量儀，二維影像測量儀等，自動影像測量儀。</p><div

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。測量儀又是通過鏡頭掃描工件來完成掃描的。半自動影像測量儀-4030MZ采購</p><p
