RVI (RemoteVisualInspection) is used to use industrial endoscopes to remotely inspect the interior of the product. As one of the non-destructive testing methods to effectively ensure product quality, it has been widely used in aerospace, energy and power, automobiles, construction and other industrial fields. With the continuous development of endoscope manufacturing technology, so far, industrial endoscopy has mainly experienced three stages.

1. The seventh and eighty generations used straight rod rigid scopes (Borescopes) and fiberscopes (Fiberscopes). The straight rod rigid lens is simple to operate, good in imaging, and relatively inexpensive, but the straight rod is limited in length and cannot be bent. Although the fiber endoscope can be used with a certain bending angle, the bending angle is longer than a straight rigid lens. However, because the number of fiber bundles connected between the objective lens and the eyepiece and the light transmission efficiency are limited, the sharpness of the image after connecting the CCD (ChargeCou-pledDevice) to the eyepiece is poor, which is more suitable for visual observation, and the glass fiber It will break when the bending angle is too large.

2. In the early 1990s, video mirrors with a minimum outer diameter of 6.0 mm appeared. It directly places a small CCD camera behind the endoscope lens and converts optical images into electrical signals for transmission. Displayed on the screen or stored in the computer through the video controller, the imaging clarity is very high, but due to the size of the CCD camera, the diameter of the lens cannot be less than 6mm, but the defects found cannot be accurately measured.

3. In 1998, a measurable video endoscope (outer diameter 8.4mm) appeared. On the basis of ordinary video endoscopes, the latest stereo measurement (simulation of the human eye dual lens) technology is used to perform video signal acquisition and image processing. The distance between the observed objects can be measured in three ways: point to point ( Length), LinetoPoint and Depth have high precision and greatly expand the scope of application of endoscopes in the field of non-destructive testing.
