What are the differences between a two-dimensional image measuring instrument and a three-dimensional measuring instrument?

With the development of manufacturing technology and standard requirements, traditional measuring tools such as vernier calipers have become more and more difficult to meet the measurement needs. High precision measuring instruments are used in more and more manufacturing enterprises. In the two-dimensional measurement Angle, there is an image measuring instrument, combined with optical projection and computer technology, on the basis of CCD digital image, relying on the computer screen measurement technology and the powerful software ability of space geometry operation and produced. And if from the three-dimensional perspective of space, it is a coordinate measuring instrument. By collecting the spatial coordinate value, the measurement element is synthesized, and the position tolerance data is calculated by the algorithm.

1. Different machine principles
Image measurement is a high-precision optical measuring instrument composed of CCD, grating ruler and other components, based on machine vision technology and micron accurate control to complete the measurement process. The measurement will be transmitted to the data acquisition card of the computer through the USB and RS232 data lines, and the optical signal will be converted into an electrical signal, and then the image will be imprinted on the computer monitor by the image measuring instrument software, and the operator will quickly measure on the computer with the mouse.

Three coordinate measuring machine. By moving on three vertical guide rails, the signal is transmitted by contact or non-contact, etc., and the three-axis displacement measurement system calculates the coordinates of each point (X, Y, Z) of the workpiece through the data processor and the instruments for the measurement of various functions.

2. Different functions
The second element measuring instrument is mainly used in the two-dimensional plane measurement field, such as some mechanical, electronic, hardware and other industries, with the probe can measure some simple shape and position tolerances, such as flatness, perpendicularity and so on.

The three-dimension measuring instrument is based on three-dimensional measurement, and can measure the size, form and position tolerance and free-form surface of complex mechanical parts.

Image measuring instrument and coordinate measuring instrument have their own scope of application, need to fully understand the use of the needs before purchasing.
