With the development of science and technology, the measurement accuracy of various jobs and parts is getting higher and higher, and the requirements for measuring instruments are becoming more and more demanding. After installing special control and graphic measurement software on the computer, the computer has become a measurement with the soul of the software. The brain is the main body of the entire device. It can quickly read the displacement data of the optical ruler, and calculate the desired result in an instant through the calculation of the software module based on the spatial geometry; and generate a graph on the screen for the operator to compare the image and shadow, so as to be able to distinguish only Possible deviations in measurement results. All of this is done in real time in front of powerful computer computing capabilities, which the operator himself cannot detect.

       This kind of precision instrument that can use CCD digital graphics and calculate by computer software to meet the needs of complex measurements is the second-dimensional image measuring instrument in the true sense. In the courseware, the computer in the image measuring instrument is not only used for simple image alignment and numerical display, but more importantly, it has spatial geometric operations, graphic display, and dimensioning. Basic functions such as the output of CAD graphics, all of which depend on special measurement and control software developed on the basis of spatial geometry.

working principle
      The secondary image measuring instrument uses its own hardware (CCD, eyepiece, objective lens data line) to transfer the captured image to the data acquisition card of the computer through the data line, and then the software images the computer display and is used by the operator. The mouse makes quick measurements on the computer. The above process is basically completed in ten thousandths of a second, so he can be regarded as a real-time detection device, or a narrower one can be called a dynamic measurement device. If the configuration meets the requirements, the device will definitely not cause image lag. Depending on the size of the workpiece, the table can choose different strokes. The brightness of the light source is adjustable, and the most suitable light source brightness can be selected under various light conditions.

use
       The instrument is suitable for all application fields with the purpose of two-coordinate measurement, and is widely used in machinery, electronics, instrumentation, hardware, plastic parts and other industries.
