我們(men)使用激光掃(sao)描(miao)儀掃(sao)描(miao)標(biao)準工(gong)件(jian)(jian)表(biao)(biao)(biao)面(mian)(mian)，收集基于點(dian)云的(de)工(gong)件(jian)(jian)表(biao)(biao)(biao)面(mian)(mian)特征(zheng)信(xin)息(xi)，將(jiang)點(dian)坐(zuo)標(biao)轉換到(dao)(dao)車(che)身坐(zuo)標(biao)下，用surfacer軟(ruan)件(jian)(jian)處理點(dian)信(xin)息(xi)，得到(dao)(dao)工(gong)件(jian)(jian)表(biao)(biao)(biao)面(mian)(mian)曲(qu)(qu)面(mian)(mian)的(de)特征(zheng)曲(qu)(qu)線，生成的(de)自由曲(qu)(qu)面(mian)(mian)模(mo)(mo)型(xing)；同時(shi)，從點(dian)云到(dao)(dao)曲(qu)(qu)面(mian)(mian)的(de)大小距(ju)離(li)可以(yi)檢測(ce)(ce)到(dao)(dao)原(yuan)始模(mo)(mo)型(xing)。需要注(zhu)意的(de)是，此時(shi)獲得的(de)模(mo)(mo)型(xing)是沒(mei)有厚度(du)的(de)片狀(zhuang)模(mo)(mo)型(xing)。根據(ju)掃(sao)描(miao)儀掃(sao)描(miao)的(de)表(biao)(biao)(biao)面(mian)(mian)，將(jiang)模(mo)(mo)型(xing)區(qu)分為工(gong)件(jian)(jian)的(de)內外表(biao)(biao)(biao)面(mian)(mian)，這(zhe)對(dui)于汽車(che)檢測(ce)(ce)工(gong)具的(de)具體(ti)設計(ji)(ji)尤為重要。為了(le)實現汽車(che)檢測(ce)(ce)工(gong)件(jian)(jian)自由曲(qu)(qu)面(mian)(mian)的(de)檢測(ce)(ce)，檢測(ce)(ce)特定表(biao)(biao)(biao)面(mian)(mian)與工(gong)件(jian)(jian)內表(biao)(biao)(biao)面(mian)(mian)之(zhi)間的(de)常數(shu)間隙一般保(bao)持在(zai)2-3mm左(zuo)右。數(shu)控加工(gong)機床可根據(ju)設計(ji)(ji)的(de)表(biao)(biao)(biao)面(mian)(mian)數(shu)模(mo)(mo)滿(man)足(zu)高精度(du)要求(qiu)。在(zai)實際(ji)檢測(ce)(ce)中，工(gong)件(jian)(jian)曲(qu)(qu)面(mian)(mian)的(de)偏(pian)差可以(yi)通過(guo)汽車(che)檢測(ce)(ce)工(gong)具表(biao)(biao)(biao)面(mian)(mian)與特殊(shu)量(liang)具的(de)往復(fu)運動來測(ce)(ce)量(liang)。
