Embodiment 1
[0162] In this embodiment, the arithmetic processor 8 adopts a method for classifying yellow cultured diamond grades based on deep learning and multi-model decision-making to perform classification and judgment, and the steps are as follows:
[0163] Step S1: Original sample image collection: through coaxial light source illumination, use CCD industrial camera and image acquisition card to collect yellow diamond images; in order to ensure image quality, the present invention uses a customized white surface light source for supplementary light, and sets the exposure of the camera at the same time The time is 150us and the frame rate is 32fps. The original sample collected is attached as Figure 14 shown;
[0164] Step S2: Sample image classification: According to the different grades of yellow diamonds, the yellow diamond samples are divided into three types of samples: first-class, second-class and third-class;
[0165] The step S2 includes the following sub-steps:
[0166]...

The invention belongs to the technical field of yellow cultivated diamond grading, and particularly relates to an automatic yellow cultivated diamond grading system based on visual identification. Thesystem comprises a raw material bin unit, a material extracting unit, a material arranging unit, a feeding unit, a conveying unit, a visual recognition unit, a discharging unit, an operation processing device and a controller. According to the novel feeding mechanism, irregular small-size yellow cultivated diamond raw materials can be lifted and tidied, one yellow cultivated diamond can be accurately picked up, automatic feeding is achieved, and the problem that it is difficult to accurately pick up one raw material from small-size and irregular raw materials each time in the prior art is solved. Moreover, the invention further provides an automatic grading system for yellow cultivated diamonds based on visual recognition, and the problems that the yellow cultivated diamonds depend on manual sorting, the labor intensity is high, and the working efficiency is low are solved.
Description
technical field [0001] The invention belongs to the technical field of grading yellow cultivated diamonds, in particular to an automatic grading system for yellow cultivated diamonds based on visual recognition. Background technique [0002] China is a big producer of industrial synthetic diamonds, and its output ranks first in the world. Due to its high hardness, industrial synthetic diamonds are widely used in the manufacture of drilling probes and grinding tools. Yellow lab-grown diamond is a high-yield product among industrial synthetic diamonds. The size is mainly concentrated in 1mm to 2mm. It has the characteristics of small size, high hardness, irregular shape, light weight, and large output. [0003] Yellow cultured diamonds have a wide range of uses. Among them, yellow cultured diamond products with regular crystal shape, low strength and high brittleness are used for light-load grinding such as grinding wheels; regular crystal shape, high mechanical strength, medi...
