Рассматриваются два оптических метода трёхмерной визуализации и применение этих методов в НК: лазерное линейное сканирование и структурированное освещение. В обоих случаях глубина дефекта определяется на основе триангуляции между источником света, объектом контроля и датчиком камеры. Оба метода показали себя как способные обеспечить точность, воспроизводимость и вероятность обнаружения достаточные для удовлетворения требованиям НК. Во второй части статьи внимание сфокусировано на применении трёхмерной визуализации к оценке коррозии трубопроводов, а именно: выявлению областей коррозии, определению максимальных потерь металла, установлению профиля коррозии и расчёту максимального безопасного давления и остаточного ресурса трубопровода.

The article focuses on two 3D optical imaging technologies and the application of these technologies to nondestructive testing: laser line scanning and structured light. Both technologies determine depth based on triangulation between a light source, the object under inspection, and a camera sensor. Both technologies have demonstrated accuracy, precision, and probabilities of detection sufficient to meet the demands of nondestructive testing. The second part of the article focuses on the application of 3D imaging in the assessment of corrosion on pipelines. In this application, 3D imaging is used to identify areas of corrosion, determine the maximum amount of metal loss, extract the river bottom profile, and calculate the remaining strength of a pipeline.
