| 摘 要： | 基于主动轮廓方法（ACM）原理，将ACM延伸开发应用到雾化锥角的测量领域.经过调试，ACM成功捕捉到了雾锥边界以及喷雾矩在喷口后一定位置处出现的收缩特征，准确地获得了雾化锥角.验证结果显示:ACM获得的雾化锥角数值与阴影法测量值之间的相对误差小于1.5%.基于ACM提取雾化锥角方法的应用可以在保证实验结果准确度的同时降低工程应用成本.

| Abstract: | Active contour model (ACM) was developed to track spray angle of atomizer. Through debugging and testing, ACM successfully captured the boundary of atomizer spray. The feature of spray contraction at downstream part of spray was also obtained, and spray angle was got exactly. The verification results show that, the relative errors between the spray angle values measured by the ACM tracking and the shadowgraph measurement are less than 1.5%. The ACM tracking spray angle can reduce cost of engineering applications with an identical measuring accuracy. |
