The flash measuring instrument is a rapid measuring mechanism which reduces the outline image of a product to tens of times through a telecentric lens with a large visual field and a large depth of field, transmits the image to a high-resolution camera for digital processing, and then captures the outline of the product by background measuring software with strong computing power and completes the computation, thereby measuring the outline size of the product. The measuring mode has the characteristics of high measuring speed and high automation degree, and is widely applied to various fields such as machinery, electronics, cables, clocks and the like at present. However, the resolution of the captured image in a small range is reduced due to the increase of the visual field of the lens, so that each group of telecentric lenses has a corresponding measurement range, and when the size of the workpiece is too large or too small, the problem that the image cannot be completely captured or displayed is not clear occurs; even if the double-view telecentric lens with different view ranges is adopted, the measuring range is generally only within 10-100 mm, and the whole measuring range cannot be covered.
On the other hand, the measurement range of the telecentric lens and the price of the telecentric lens are exponentially corresponding, namely, after the measurement range of the telecentric lens is increased, the price of the telecentric lens is multiplied by several times or even ten times of the original price, so that a manufacturer cannot realize large-scale size measurement through direct type selection.
