中文摘要:设计了基于Matlab/GUI的汽油机缸内直接喷雾图像实时处理程序,实现了图像处理的可视化操作。由于汽油挥发性较强,使得汽油机缸内直接喷雾图像相对柴油喷雾图像而言,雾形边界相对模糊,且喷雾图像信噪比较差。为准确提取汽油机缸内直接喷雾研究中所需的喷雾贯穿距、喷雾锥角、周长以及面积等参数,需要在图像处理过程中精确地提取喷雾边界,为此进行了精确的噪声滤波、边缘检测、形态学优化等图像处理。在确定雾形边界后,进一步编写程序计算出喷雾贯穿距、喷雾锥角、喷射速度等参数,实现了喷雾特性参数的实时测量。

Abstract:An image processing program with good instantaneity for gasoline direct injection spray based on Matlab/GUI was designed and the program realized visual operation interface. As gasoline is fuel with great volatile, the spray boundary of GDI image is relative obscure and SNR of the spray image is not satisfied compared with that in diesel injection. To get the accurate spray penetration, cone angle, perimeter, area and other needed parameters, the spray boundary was precisely extracted in the image processing. Noise filtering, boundary detection,morphological analysis and other related methods have been used. After the spray boundary was obtained, program to calculate spray penetration, cone angle, injection velocity and other parameters was developed to realize real-time measurement of spray parameters.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
