Claims (1)

Изобретение относится к области обработки прозрачных камней (ПК), а именно, к способам определения положения дефекта (Д) в ПК преимущественно с большим показателем преломления. Цель изобретения - увеличение точности и производительности. Изобретение предусматривает определение истинного положения Д в ПК в плоскости изображения регистрирующего прибора и пространственного положения Д. Измерения производят при помещении ПК в разные среды с использованием вычислительной техники.The invention relates to the field of processing of transparent stones (PC), namely, to methods for determining the position of the defect (D) in the PC mainly with a large refractive index. The purpose of the invention is to increase accuracy and performance. The invention provides for determining the true position of D in the PC in the image plane of the recording device and the spatial position of D. The measurements are made when the PC is placed in different environments using computer technology.
