摘要: The inspection for the inner wall is necessary during life of a pipe from production to condemnation. A corresponding optical system has been developed. This uses motion complicated mechanism in axial direction droved by stepper motor, and detection panoramic images illuminated circumferential surface realized hemispherical imaging (HPIS). Irregularities due corrosion or accumulation brass deposits on are inspected this system. experimental reported article following specifications: resolution 0.3 mm at circumference 1.1 pipe, speed 15 mm/s an interval 0.5 mm.
