Two dimensional image measuring instrument
Two dimensional image measuring instrument (also known as image mapping instrument) is built on the basis of CCD digital images, relying on the computer screen measurement technology and the space of the geometric operations of the powerful software. After the computer is installed on the special control and graphics software, it has become the soul of the software to measure the brain, is the main body of the whole equipment. The displacement value it can quickly read the optical length, through the operation of software module is established in the space geometry on the basis of the results obtained by the moment; and generating graphics on the screen, for the operator to control the image, which can visually distinguish the possible deviation of measurement results. All this, in today's powerful computing capabilities of the computer is done in real-time, the operator can not be aware of. This can make use of CCD digital images, through the computer software computing, to meet the needs of complex measurement of precision instruments is the true sense of the two dimensional image measuring instrument. Therefore, the image measuring instrument in the computer not only shows the simple image registration and numerical, more important is to have the space geometry processing, graphic display, dimension, the basic function of CAD graphics output, the special software of the measuring and control it all depends on the development in the space geometry on the basis of.
