Abstract

In the industrial production process, the interior of machines is prone to quality problems such as rust and damage due to factors like corrosion and impact, and the complex internal structure makes it difficult to observe directly. As a non-destructive testing tool, traditional industrial endoscopes can penetrate into curved pipes and areas that are out of reach of the human eye, achieving imaging, recording and storage of internal conditions. This article systematically expounds the optical imaging principle of traditional endoscopes, the standard operating procedures, and their practical applications in typical scenarios such as engine oil passage burrs and iron filings in bolt holes. Meanwhile, the limitations of traditional endoscopes in terms of imaging quality, detection range, detection efficiency and functional diversity were analyzed. Analysis shows that although traditional endoscopes have met the basic needs of visual inspection, their reliance on visual judgment and lack of automatic recognition and three-dimensional measurement capabilities have made it difficult to meet the development requirements of modern industrial precision manufacturing.
