Instant vision measuring machine is a new image measurement technology, which is different from the traditional two-dimensional video measuring machine in that it no longer needs the grating scale displacement sensor as the accuracy mark, nor does it magnify the product image through a large focal length lens to ensure the measurement accuracy.
The instant vision measuring machine uses a telecenter lens with a large Angle of view and a large depth of field to shrink the product contour image several times or tens of times, and then transmits it to the ultra-high pixel camera for digital processing. Then, the background mapping and measuring software with powerful computing capability can quickly capture the product contour according to pre-programmed instructions. Finally, the product size is calculated by comparing with the scale formed by the small pixels of the high pixel camera, and the dimensional tolerance is evaluated at the same time.
Instant vision measuring machine body structure is simple, do not need displacement sensor grating ruler, only need large Angle of view and depth of field telecentric magnate lens, high pixel camera and powerful computing power background software.
