影像測量儀的技術探討

    影像測量儀和影像對位投影儀（真假影像測量儀）

  【圖像測量】是工業檢測與測量技術領域的一個新名詞。它代表了一種先進的測量技術，將數字技術融入工業檢測和測量，并進行空間幾何運算。正是因為它的尖端性不為大眾所熟知，如今很多【圖像對位測量投影儀】才成為時尚，并稱自己為“圖像測量儀”。

   真正的【影像測量儀】（又稱影像測繪儀）是建立在CCD數字影像的基礎上，依托計算機屏幕測量技術和強大的空間幾何運算軟件能力。計算機安裝專用的控制和圖形測量軟件后，就成為具有軟件靈魂的測量大腦，是整個設備的主體。它可以快速讀取光學尺的位移值，通過基于空間幾何的軟件模塊的操作，在瞬間得到想要的結果。并在屏幕上生成圖形，供操作者比較圖像和陰影，從而直觀地區分測量結果可能存在的偏差。這一切都是在當今強大的計算機計算能力面前實時完成的，操作者自己無法察覺。這種能夠利用CCD數字圖像和計算機軟件來滿足復雜測量需要的精密儀器才是真正的圖像測量儀器。

    可以看出，影像測量儀中的計算機不僅進行簡單的數值顯示，還具備空間幾何運算、圖形顯示、尺寸標注、CAD圖形輸出等基本功能，這些都依賴于功能強大的專用軟件。

   【影像對位式測量投影儀】有一個非常突出的特點，那就是：它既有【數字顯示屏】又有電腦。這個功能本身就很搞笑，因為既然有電腦顯示器，那么【數顯屏】應該是沒有意義的，電腦能顯示的信息格式和容量真的是超出數顯屏的。影像投影測量儀中的電腦實在是太可憐了，只相當于一臺帶十字發生器的電視機或顯示器。它僅用作視覺對準的“靶場”，并成為冒名頂替者。一堆完全沒有“智能”的電子機械。因此，辨別真假影像測量儀器并不難。首先要看它是否有額外的數字顯示屏，其次看它是否具備空間幾何計算能力。

Image measuring Instrument and Image Projector (true and false image measuring Instrument)

Image measurement is a new term in the field of industrial detection and measurement technology. It represents an advanced measurement technology that incorporates digital technology into industrial inspection and measurement, as well as spatial geometric operations. It is precisely because of its cutting-edge is not known by the public, many [image measurement projector] has become fashionable and call themselves "image measurement instrument".

The real [image measuring instrument] (also known as image mapping instrument) is built on the basis of CCD digital image, relying on computer screen measurement technology and powerful space geometry operation software ability. After the computer is installed with special control and graphic measurement software, it becomes the measurement brain with software soul, which is the main body of the whole equipment. It can quickly read the displacement value of the optical ruler and obtain the desired result in an instant through the operation of the software module based on spatial geometry. And generate graphics on the screen for the operator to compare images and shadows, so as to intuitively distinguish the possible deviation of the measurement results. All this is done in real time, in the face of today's powerful computer computing power, undetected by the operator himself. This kind of precision instrument that can use CCD digital image and computer software to meet the needs of complex measurement is a true image measurement instrument.

It can be seen that the computer in the image measuring instrument not only carries on the simple numerical display, but also has the space geometry operation, the graph display, the dimension marking, THE CAD graph output and other basic functions, which all depend on the powerful special software.

There is a very prominent feature of the projector, that is: it has both a digital display screen and a computer. This feature is funny in itself, since there are computer monitors, then [digital display] should not be meaningful, computers can display information format and capacity is really beyond digital display. The computer in the image projection meter is so pitiful that it is equivalent to a TELEVISION or monitor with a cross generator. It serves only as a "shooting range" for visual alignment and becomes an impostor. A bunch of electronic machines with no "intelligence" at all. Therefore, it is not difficult to distinguish between real and fake image measuring instruments. The first thing to see is whether it has additional digital display, followed by whether it has spatial geometric computing capacity.
