Paper Abstract

As an embranchment of nondestructive testing, the industrial borescope plays an important role in fields of industrial fault diagnosing, quality controlling and product evaluating from its beginning. The electronic borescope adopts the latest technology and is widely used now. A new portable industrial electronic borescope is designed based on CMOS image sensor and embedded system. It consists of four parts: lighting, imaging lens, CMOS camera and embedded system for image acquisition and processing, which has the advantages of small volume, low power consumption, and portable. The optic system uses a reverse-telephoto configuration lens. The white LED is used as light source. A 3.6μm pixel size of 640*480 image array CMOS image sensor is adopted. The embedded system is designed based on ARM microprocessor as main control and processing unit. In software image processing technique is used to improve the image. The diameter of electronic borescope probe is 10mm. It can inspect surfaces inside narrow tubes or difficult-toreach chambers like inside engine.
