Quantitative measurement method for limpidity of emulsified diesel oil

Abstract

The invention discloses a quantitative measurement method for limpidity of emulsified diesel oil. The quantitative measurement method comprises the following steps of: acquiring a gray level image of an oil product; calculating the difference between each row of pixel value and a last row of pixel value in the gray level image of the oil product, so as to obtain a run error figure D of the gray level image f of the oil product; calculating and accumulating a run error figure P; carrying out binaryzation on the accumulated run error figure P, so as to obtain a binaryzation image B of the accumulated run error figure P; extracting possible calibration lines; detecting calibration line regions; calculating a pixel mean value fb of a calibration line region Bf; calculating the pixel mean value of an oil product background region Bg in an oil product image f; and calculating a diversity factor FD. According to the quantitative measurement method disclosed by the invention, a computer is utilized for automatically analyzing and processing the acquired oil product image and finally obtaining a difference value between the pixel mean value of the calibration line region and the pixel mean value of the oil product background region, and by utilizing the difference value as the diversity factor, the limpidity of the oil product can be fast and quantitatively determined. According to the quantitative measurement method, the calculation is simple,the run time is short, and real-time systems can be facilitated.

Description

technical field [0001] The invention relates to a method for quantitatively measuring the clarity of emulsified diesel oil. Background technique [0002] With the rapid and stable development of my country's economy, the development process of urbanization and industrialization will be further accelerated, and the demand for oil resources in various fields will increase greatly. However, the growth rate of my country's oil production is restricted by many factors, which is much lower than the demand for oil The growth rate of consumer demand and the severe energy situation will further aggravate the risk of my country's oil supply, leading to a very severe situation in my country's oil security in the future. Therefore, the development of new energy and energy-saving technologies are very important to our country. As a new technology for diesel engines to reduce diesel consumption and improve emissions, micro-emulsion diesel has a micro-explosion effect, which can realize sec...

At present, the method for judging the clarity of oil products is mainly as follows: After the oil product is prepared, it is left to stand for a period of time, and after the researchers observe with the naked eye, a qualitative conclusion is given from the appearance of the oil product whether it is clear or not; When the subjective judges are different, the conclusions given will be different, and it is impossible to give a quantitative judgment of the oil clarity. Clarity is especially important
