摘要 隨著科學(xué)技術(shù)的不斷發(fā)展，測(cè)量技術(shù)也隨著新的物理原理和新的技術(shù)成就的不斷引入，而獲得長(zhǎng)足發(fā)展。隨著計(jì)算機(jī)技術(shù)、光學(xué)和光電子技術(shù)的迅猛發(fā)展，光學(xué)三維輪廓測(cè)量技術(shù)有了極大的改變。光學(xué)三維輪廓測(cè)量技術(shù)具有非接觸、高精度、高效率的特點(diǎn)，在機(jī)械視覺(jué)、自動(dòng)加工、實(shí)物模型、工業(yè)檢測(cè)、生物醫(yī)學(xué)等領(lǐng)域，有著重要的應(yīng)用價(jià)值和廣闊的應(yīng)用前景。 非接觸檢測(cè)采集的離散數(shù)據(jù)點(diǎn)，都會(huì)存在一些噪音，這些噪音對(duì)曲面形狀恢復(fù)有負(fù)面影響，不利于曲面匹配和曲面形狀誤差分析，這些噪音點(diǎn)需要剔除掉。在三維坐標(biāo)測(cè)量曲面數(shù)據(jù)時(shí)，測(cè)量坐標(biāo)系與理論坐標(biāo)系之間往往不重合，要進(jìn)行加工曲面形狀誤差求解，必須進(jìn)行曲面數(shù)據(jù)匹配。在非接觸檢測(cè)數(shù)據(jù)處理過(guò)程中，數(shù)據(jù)配準(zhǔn)是十分重要的部分。目前，ICP 算法在配準(zhǔn)問(wèn)題上應(yīng)用最為普遍。 本課題主要研究非接觸光學(xué)檢測(cè)傾斜角度對(duì)表面誤差影響的關(guān)系，經(jīng)過(guò)實(shí)例驗(yàn)證和理論分析，我們得出了結(jié)論：隨著檢測(cè)角度越來(lái)越大誤差也越來(lái)越大的關(guān)系。在60°這是一個(gè)分界點(diǎn)，60°前誤差都是隨著角度的增加而平緩增加的，檢測(cè)角度到了60°左右這檢測(cè)誤差就會(huì)變得很不穩(wěn)定了，突然有直線上升的趨勢(shì)。 關(guān)鍵詞：三維模擬；曲面匹配；ICP；非接觸檢測(cè)
Abstract With the continuous development of science and technology, measurement technology with the new physical principles and new technological achievements, the continuous introduction of, and access to substantial development. With computer technology, optics and photonics technology, the rapid development of optical three-dimensional profile measurement techniques have greatly changed. Optical surface profile measurement with non-contact, high precision and high efficiency features in machine vision, automatic processing, physical models, industrial inspection, biomedical and other fields, important application value and application prospect. The discrete point data collected by the non-contact technology , will exist some noisy ,which can have impact for the recovering of surface ,so not favorable to the surface matching and error analysis ,so the noise must need to remove . When detecting the surface data in the three-dimension coordinate, because often Measurement coordinate system does not coincide with theory coordinate system, we have to match the surface data if we want to analysis the surface error. Nowadays, ICP algorithm is the most common used. This research project mainly non-contact optical inspection tilt effect on the relationship between the surface error, and validated through theoretical analysis, we come to the conclusion: With the growing point of error detection is also growing relationship. At 60 ° This is a demarcation point, 60 ° angle before the error is increased with the gentle increase in the detection angle to 60 ° around the test error will become very unstable, and suddenly there is a rising trend line. Key Words: 3D simulation; surface match; ICP; non-contact detection
