影像測(cè)量?jī)x是一種新型的精密幾何測(cè)量?jī)x器。 隨著技術(shù)的發(fā)展，它已成為精密幾何測(cè)量中最常用的測(cè)量?jī)x器之一。 圖像測(cè)量?jī)x利用圖像探頭采集工件的圖像，通過(guò)數(shù)字圖像處理技術(shù)提取各種復(fù)雜形狀工件表面的坐標(biāo)點(diǎn)，再利用坐標(biāo)變換和數(shù)據(jù)處理技術(shù)轉(zhuǎn)換成各種幾何元素 在坐標(biāo)測(cè)量空間。 從而可以計(jì)算出待測(cè)工件的實(shí)際尺寸、形狀和相互位置關(guān)系。

        經(jīng)過(guò)不斷的發(fā)展，影像測(cè)量?jī)x的應(yīng)用范圍不斷擴(kuò)大，可以準(zhǔn)確測(cè)量各種復(fù)雜的工件輪廓和表面形狀。 目前，影像測(cè)量?jī)x的測(cè)量對(duì)象包括電子零件、精密模具、沖壓件、PCB板、螺紋、齒輪、成型工具等工件，并逐步進(jìn)入電子、機(jī)械、儀表、鐘表、輕工、國(guó)家 國(guó)防軍工、航空航天等行業(yè)已成為高等院校、科研院所、計(jì)量技術(shù)機(jī)構(gòu)的實(shí)驗(yàn)室、計(jì)量室和生產(chǎn)車(chē)間常用的精密測(cè)量?jī)x器。 今天我們主要討論影像測(cè)量?jī)x在模具行業(yè)的應(yīng)用。

       模具測(cè)量的范圍非常廣泛，包括模型測(cè)繪、模具設(shè)計(jì)、模具加工、模具驗(yàn)收、修模后檢驗(yàn)、模具成型產(chǎn)品批量檢驗(yàn)等諸多領(lǐng)域。 每個(gè)領(lǐng)域都需要高精度的尺寸測(cè)量，包括距離、角度、高度、孔徑、圓弧半徑、曲面等幾何量，以及圓度、直線度、平面度、垂直度、平行度、同軸度等幾何公差。 另一方面，各個(gè)領(lǐng)域的測(cè)量要求也不同。 最典型的就是模塑制品的模型測(cè)繪批檢：模型測(cè)繪涉及到尺寸的綜合測(cè)量，對(duì)測(cè)量效率要求不高，對(duì)儀器功能要求高。 成型品的批量檢測(cè)對(duì)測(cè)量效率的要求非常高。

       傳統(tǒng)的接觸式三坐標(biāo)測(cè)量機(jī)、關(guān)節(jié)臂測(cè)量機(jī)、大尺寸激光跟蹤儀等儀器也廣泛應(yīng)用于模具測(cè)量領(lǐng)域。  ，沒(méi)有好的解決辦法。 借助CCD面陣傳感器和非接觸式測(cè)量的特點(diǎn)，影像測(cè)量?jī)x可以高效完成無(wú)法接觸、易變形、外形小巧的工件，在這方面具有絕對(duì)優(yōu)勢(shì)。

        在逆向工程領(lǐng)域映射模具時(shí)，為了快速掃描曲面，需要昂貴的掃描探頭或激光掃描探頭。 鑫天光電銷售的影像測(cè)量?jī)x具有自動(dòng)輪廓掃描功能，可以獲取同一輪廓上所有點(diǎn)的坐標(biāo)，從而獲得工件的輪廓圖。 自動(dòng)輪廓掃描功能操作簡(jiǎn)單，效率很高。 操作者只要指定掃描開(kāi)始和結(jié)束位置，機(jī)器就會(huì)自動(dòng)搜索掃描方向，移動(dòng)工作臺(tái)，獲取點(diǎn)集的坐標(biāo)，快速獲取工件的輪廓。 經(jīng)濟(jì)高效的解決方案。

       模具成型零件的特點(diǎn)是量大、計(jì)量效率要求高。 傳統(tǒng)的接觸式三坐標(biāo)雖然具有自動(dòng)測(cè)量的功能，但效率遠(yuǎn)遠(yuǎn)不能滿足批量測(cè)量的要求。 新天光電提供的圖像測(cè)量?jī)x采用CCD采集圖像進(jìn)行測(cè)量。  CCD是一種面陣傳感器，可以一次獲取一個(gè)區(qū)域的圖像。 對(duì)于幾何量的測(cè)量，測(cè)量效率遠(yuǎn)高于接觸式三坐標(biāo)。 借助二維測(cè)量軟件的圖元復(fù)制、多坐標(biāo)系、報(bào)表定制輸出等功能，可以快速構(gòu)建測(cè)量程序，高效獲取所需數(shù)據(jù)。

       影像測(cè)量?jī)x以其非接觸式、高效率、高性價(jià)比的優(yōu)勢(shì)，日益成為模具行業(yè)重要的測(cè)量工具。

Image measuring instrument is a new type of precision geometric measuring instrument.  With the development of technology, it has become one of the most commonly used measurement instruments in precision geometric measurement.  The image measuring instrument uses the image probe to collect the image of the workpiece, extracts the coordinate points on the surface of the workpiece with various complex shapes through the digital image processing technology, and then converts them into various geometric elements in the coordinate measuring space by using the coordinate transformation and data processing technology.  The actual size, shape and position of the workpiece can be calculated.  

After continuous development, the scope of application of image measuring instrument is expanding, it can accurately measure various complex workpiece contour and surface shape.  At present, the measurement objects of the image measuring instrument include electronic parts, precision molds, stamping parts, PCB boards, threads, gears, forming tools and other workpiece.  And gradually into electronics, machinery, instrumentation, clocks and watches, light industry, national defense military industry, aerospace and other industries has become colleges and universities, scientific research institutes, measurement technology institutions of laboratories, measuring rooms and production workshops commonly used precision measuring instruments.  Today we mainly discuss the application of image measuring instrument in mould industry.  

The scope of mold measurement is very wide, including model mapping, mold design, mold processing, mold acceptance, mold repair inspection, mold molding products batch inspection and many other fields.  Every field requires high-precision dimensional measurement, including geometric quantities such as distance, Angle, height, aperture, radius of arc and surface, as well as geometric tolerances such as roundness, straightness, flatness, verticality, parallelism and coaxiality.  On the other hand, measurement requirements vary from field to field.  The most typical is the model mapping inspection of molded products: model mapping involves comprehensive measurement of size, low requirements for measurement efficiency and high requirements for instrument function.  The batch inspection of molding products requires very high measurement efficiency.  

Traditional contact CMM, joint arm measuring machine, large size laser tracker and other instruments are also widely used in the field of mold measurement.  There is no good solution.  With the CCD array sensor and the characteristics of non-contact measurement, image measuring instrument can efficiently complete the workpiece that can not be contacted, easy to deformation, small shape, and has absolute advantages in this respect.  

When mapping molds in reverse engineering, expensive scanning probes or laser scanning probes are needed to quickly scan surfaces.  The image measuring instrument sold by Xintian photoelectric has the function of automatic contour scanning, which can obtain the coordinates of all points on the same contour, so as to obtain the contour map of the workpiece.  The automatic contour scan function is simple and efficient.  As long as the operator specifies the starting and ending positions of the scan, the machine will automatically search the scanning direction, move the workbench, obtain the coordinates of the point set, and quickly obtain the contour of the workpiece.  Cost effective solution.  

The characteristics of mold forming parts are large quantity, high measurement efficiency requirements.  Although the traditional contact CMM has the function of automatic measurement, its efficiency is far from meeting the requirements of batch measurement.  The image measuring instrument provided by Xintian Photoelectric uses CCD to collect images for measurement.  CCD is a planar array sensor that can capture images of one area at a time.  For the measurement of geometric quantity, the measurement efficiency is much higher than contact CMM.  With the help of the functions of 2d measurement software such as pixel duplication, multi-coordinate system and report form customization output, the measurement program can be constructed quickly and the required data can be obtained efficiently.  

Image measuring instrument with its non-contact, high efficiency, high cost performance advantages, increasingly become an important tool for mold industry measurement.
