第二種測(cè)量強(qiáng)度的方法是使用視覺(jué)系統(tǒng)的相機(jī)。相機(jī)不是經(jīng)過(guò)校準(zhǔn)的傳感器-兩個(gè)相同品牌和型號(hào)的相機(jī)將具有不同的靈敏度。所以測(cè)量是相對(duì)的。然而，目標(biāo)是獲得正確的曝光；因此，使用視覺(jué)系統(tǒng)的攝像機(jī)進(jìn)行測(cè)量實(shí)現(xiàn)一部分目的——知道成像設(shè)置滿(mǎn)足其要求。但是，它不能保證成像設(shè)置可以被復(fù)制。請(qǐng)參閱上面的“圖像亮度基準(zhǔn)”。

好用均勻反射的靶標(biāo)覆蓋視野。對(duì)于大多數(shù)照明方法，這個(gè)靶標(biāo)應(yīng)該是漫反射的。一些有用材料的例子是照相灰卡（一面反射18%，另一面反射90%）。對(duì)于非常大的視野，可能有必要借助于紙張或布料的背景，但期望這些產(chǎn)品的制造商控制其產(chǎn)品的反射率是不切實(shí)際的，并且測(cè)量的再現(xiàn)性也會(huì)受到影響。

有時(shí)，視覺(jué)系統(tǒng)是用來(lái)成像鏡面反射光的。在這些情況下，使用漫反射背景可能無(wú)法提供令人滿(mǎn)意的基準(zhǔn)強(qiáng)度方法。如果物體是平面的，那么背景可以是適當(dāng)尺寸的平面鏡。如果被成像的對(duì)象是一個(gè)更復(fù)雜的形狀，那么除了使用漫反射背景外，很難對(duì)強(qiáng)度進(jìn)行基準(zhǔn)測(cè)試，這種情況下，難以進(jìn)行基準(zhǔn)量化。

背景設(shè)置到位后，使用照明設(shè)置和相機(jī)參數(shù)設(shè)置捕捉場(chǎng)景圖像。讓視覺(jué)系統(tǒng)計(jì)算并報(bào)告場(chǎng)景的大和平均灰度。您確保視覺(jué)系統(tǒng)報(bào)告的大灰度值不是視覺(jué)系統(tǒng)可用的大值（例如，對(duì)于具有8位像素的視覺(jué)系統(tǒng)，大灰度值不能為255）。如果報(bào)告了大的灰度值，這表示相機(jī)處于飽和狀態(tài)，則大讀數(shù)無(wú)效，平均灰度讀數(shù)受損。除了少數(shù)例外，相機(jī)在飽和狀態(tài)下工作是不可取的。
