Embodiment Construction

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] refer to Figure 1-Figure 5 As shown, the method for restoring the original design of round brilliant-cut gemstones using image processing technology provided by the present invention includes the following steps,

[0033] The first step is to use the image acquisition system to collect the front view images of the gemstones to be restored from multiple angles, and obtain the front view images of each frame;

[0034] Wherein, the image acquisition system in the present invention includes a base 8, a parallel light source 1 with adjustable brightness, a support rod 2 and a microscope 6 installed on the base 8 in sequence, and a stepper for driving the support rod 2 to rotate on the base 8 Motor 4, the stepper motor driver 5 that is connected with stepper motor 4, the CCD camera 7 that is installed on one end of microscope 6, an...

Abstract

The invention discloses a method for restoring the original design of a bright circular polished gemstone by using an image processing technology. The method includes the steps that S1, an image collecting system is used for collecting front view images at various angles of the gemstone to be restored, and each frame of front view image is further obtained; S2, an image processing method is used for extracting edge feature points of all the frames of front view images in the S1; S3, the edge feature points in the S2 are calculated, and the edge feature points of all the frames of front view images are screened; S4, the edge feature points screened in the S3 are used as parameters to be input to three-dimensional software so that three-dimensional modeling can be conducted, and thus the original design of the gemstone can be restored. According to the method for restoring the original design of the bright circular polished gemstone by using the image processing technology, only a small amount of digital graphical information of the gemstone to be restored needs to be processed, a three-dimensional model of the original design of the gemstone can be restored, and the advantages of being high in restoring precision, high in efficiency and strong in practicability are achieved.

Description

technical field [0001] The invention relates to the technical field of gemstone design, and more specifically relates to a method for restoring the original design of round brilliant-cut gemstones by using image processing technology. Background technique [0002] Artificial gemstones are in great demand in domestic and foreign markets, but the quality of artificial gemstone cutting varies. And at present, the country or the industry has no product classification standards for artificial gemstones. It is only to regulate the processing, production and delivery trade of the local gemstone industry. basis for inspection. In this standard, the four factors of color, clarity, cut, and smoothness are the evaluation indicators for grading artificial gemstones, and cut is a very important factor. [0003] There are two reasons for the uneven quality of gemstones: one is that the gemstone processing cannot meet the requirements; the other is that the original design of the gemston...
