Abstract

The invention discloses an alloy analysis visual positioning method, a device and an alloy analysis system. The method comprises the steps: obtaining the distance between image collection equipment and a to-be-detected sample when a robot controls the image collection equipment to move to the to-be-detected sample, wherein the image acquisition equipment is provided with a structure light source;if the distance between the image acquisition equipment and the to-be-detected sample is equal to the preset distance, controlling the image acquisition equipment to shoot the surface of the to-be-detected sample to obtain a sample image; extracting a plurality of structured light stripes from the sample image; determining an optimal detection point according to the central point set of each structured light stripe, and calculating three-dimensional position coordinates of the optimal detection point, wherein each central point set comprises other pixel points except the pixel points of the edge areas on the two sides in the corresponding structured light stripe. According to the method, the three-dimensional position coordinates of the optimal detection point can be calculated only by shooting one sample image in the detection area, the calculated amount is reduced, a complex image processing process is not needed, and the calculation and positioning efficiency is higher.

Description

technical field [0001] The present application relates to the technical field of visual inspection, in particular to a visual positioning method, device and alloy analysis system for alloy analysis. Background technique [0002] With the development of optics, computer and image processing technologies, optical non-contact measurement has the advantages of fast measurement speed and high measurement accuracy, and is widely used in various fields. For example, in the iron and steel industry, due to the diversification of products, its production level tends to be automated and refined. In order to prevent the mixing of different steel grades, it is necessary to analyze the alloy composition of the finished wire rod. [0003] In the analysis of alloys, the structured light measurement system is currently used to locate the best detection point on the sample surface. The structured light measurement system is mainly composed of a structured light projection device, a camera, an...
