Embodiment Construction
[0049] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.
[0050] as attached figure 1 As shown, a metal surface rust resistance test platform is mainly composed of a test platform and a data acquisition platform. Among them, the test platform is used to test the anti-rust performance of the surface of the metal sample, and accelerate the generation of corrosion on the surface of the metal sample by controlling environmental factors. It includes four modules: input device, control device, output device and execution device; data acquisition platform It is used to collect the image data of the metal sample on...

The invention provides a metal surface anti-rust performance testing platform and anti-rust performance evaluation method. The test platform can realize the accelerated corrosion experiment on the surface of the metal sample, and the data acquisition platform can collect image data of the metal sample on the test platform. Aiming at the analysis of the image data obtained by the test bench, a set of corrosion area segmentation method is constructed, which can segment the corrosion area of the metal surface from the image, calculate the corrosion ratio index and compare it with the preset threshold, and judge the metal test area. Whether the sample has reached the termination condition of the experiment at this time. When the corrosion ratio index of the metal sample exceeds the preset threshold, the rust resistance test of the sample is completed. After the entire experiment is completed, count the time from the first run of the test platform to the last time that each metal sample is taken out. The time difference between the two is the quantitative index of the rust resistance test of the metal sample. The longer the time difference, the The better its anti-rust performance.
Description
technical field [0001] The invention relates to the fields of metal surface anti-rust performance testing, image segmentation and quality inspection and evaluation, in particular to a metal surface anti-rust performance testing platform and a method for segmenting rust areas and anti-rust performance evaluation in the anti-rust performance testing test. Background technique [0002] Metal components are widely used in various engineering facilities, and because the metal surface is affected by various environmental factors, corrosion has become an important factor for its failure. Therefore, the rust resistance of the metal surface is directly related to the safe operation of the entire equipment. Building a set of metal surface anti-rust performance test bench and test evaluation method to test its anti-rust performance and analyze the anti-rust quality of the product will help to understand and quantify the anti-rust performance of metal samples more clearly. In order to ...
