摘要/Abstract

摘要： 针对采用RTR技术获取固体火箭发动机（SRM）燃烧室中凝相粒子运动图象的特点，应用了背景减影、图象增强、图象分割、噪声过滤、图象叠加等图象处理手段对其进行处理，获得了较清晰的粒子运动轨迹图象。结果表明图象处理技术是开展利用RTR技术进行SRM二相流研究的关键环节之一。

Abstract: The digital image processing technique has been applied to deal with RTR images of moving condensed particles in a firing solid rocket motor chamber, which includes background subtraction, image enhancement, image segmentation, noise filtration and image addition. Relatively clear condensed particle trajectories have been obtained successfully. It is concluded that image processing technique is one of key links in investigation on two-phase flow of SRM using RTR technique.
