Working principle and shopping choice of video measuring machine 

Working principle

Video Measuring Machine  is an artificial intelligence technology based on machine vision, such as automatic edge extraction, automatic matching, automatic focusing, measurement synthesis, image synthesis, etc. It has excellent functions such as automatic measurement of where to go, automatic measurement of CNC position, automatic learning of batch measurement, image map target guidance, full-field Hawk-Eye enlargement and so on. At the same time, the auto-focusing process based on machine vision and micron precise control can meet the needs of assistant measurement under clear image, and also can add contact probe to complete coordinate measurement. Excellent software performance supporting spatial coordinate rotation can be used to classify batch measurement and SPC results when workpieces are placed at will or fixtures are used.


Shopping choice

Many customers are puzzled about how to choose the model brand of the video measuring machine. In fact, the most worrying thing is the quality and after-sale of the video measuring machine. Most of the manufacturers of domestic image measuring instruments are concentrated in Guangdong, and most of the developed software functions are similar. Customers can choose a product itinerary that can meet the needs of measurement without worrying. It is cheaper to choose whether to do it automatically or manually according to the need. Fully automatic is about twice as expensive as manual.

The most important thing to choose an video  measuring machine is whether the image is clear or not, and whether the accuracy is up to the standard (the general accuracy selection standard is 1/3~1/8 of the total distance of the tolerance band). All the captured images are transmitted to the data acquisition card of the computer through the data line, and then the image is imaged on the computer display by the software, and the operator uses the mouse to make rapid measurements on the computer. In order to save costs, some manufacturers may adopt home-made ones, which are relatively low in cost and have a slightly worse effect.
