Introduction image measuring instrument:

Imaging device, image measuring instrument, precision mapping instrument image. It is a qualitative leap in the basic measuring projector on a computer screen, it will be measured from the industrial measurement of optical projection on the traditional to rely on in times of digital images. It is worth mentioning that, there is a transitional product a with digital display screen and then the computer is currently on the market. Strictly speaking, this is only the computer as a tool equipment aiming not image measuring instrument, can only be called " image measuring projector " or "image alignment type projector ".

Image measuring instrument __ overview

Image measuring instrument is also called, profile projector or referred to as projector, namely vertical projector, it is the use of optical principles the workpiece contour through a lens and mirror projection, and amplified into various multiples, first projected onto the projection screen translucent, coupled with a variety of standard image, as a non-contact measurement of the.

Image measuring instrument __ classification

According to the projection path can be divided into ( a ) vertical projector ( b ) landing type projector (c) horizontal projector. The projector and the lighting electricity, light through the filter lens, lens group, table plate, reflector, projection screen, the contour or surface of the workpiece after amplifying and projection screen projection to translucent. Usually, must adjust the workpiece and the projection lens to the appropriate focal distance, the projection screen to the clear condition, in order to ensure the structural accuracy of image measuring instrument workpiece measurement, can be composed of three different measurement systems, and have different structure. If the vertical projector, for example, the projection lens by magnification 25X to 225x, and there are commonly used 10x, 20x, 50x, 100x four. Measurement of the workpiece is available lighting contour or surface reflection lighting. Accessories include rotary filling station, micrometer head ( mechanical or optical lens ), display, V block, the center top frame, various magnification ( optional replacement ), projection screen, the standard picture, glass scale and photographic equipment.

The principle of image measuring instrument __ work

Image measuring instrument between the measurement points A, B distance operation steps: first shake X, Y direction handle positioning alignment A point, and then lock the platform, and the clicking of the mouse to operate the computer determined; then open platform, repeat the above action determine B. Each click of the mouse to the significance of grating ruler displacement numerical read the points to the computer, when the value of all points are read only after the calculation function operation. As a technology of " building blocks of assorted cold dishes ", all functions and operations are separated; a handle, a little mouse; hand also need to pay attention to uniform and light and slow, can not rotate; in general, probably take several minutes for a simple distance measure is a skilled operator.

Image measuring instrument __ applications

Camera image measuring instrument is the application of amplification, can be used for length, angle, shape, surface inspection. Non - contact, the two dimension measurement, especially suitable for measurement of elastic, brittle materials. In addition to the use of photography, two dimensional coordinate processor, digital display, light eyes to read data from or automatic edge finder, printer interface equipment, advantages and can be used with the computer to do quickly, and statistic analysis. And is widely used in large pieces of sheet metal, the PCB board and the knife mold, the most popular TFT industry backlight, insulation material, surface version, border industry, BGA, plastic products, hardware, mould, mobile phone shell, electronic, nameplate, ceramic, insulating materials, medical equipment and other fields, to achieve a rapid detection mass.
