摘    要:针对固体火箭发动机飞行试验中喷管排出的羽流烟雾光学信号的准确测量,应用数字图像处理技术提取羽流烟雾的静态和动态特征进行羽烟识别。为了滤除外场复杂环境对烟雾测量的干扰,设计了具有等间距的黑白条纹背景板。在黑条纹区域采用自适应的灰度阈值提取烟雾特征,在白条纹区域根据RGB和HSV颜色空间综合的方法提取烟雾特征,结合帧间差分法提取视频序列中烟雾区域的扩散边界。基于烟雾静态和动态特征综合的算法编写了烟雾处理软件,通过处理大量烟雾视频数据进行验证试验,证明羽流烟雾的识别能够有效提高光学信号测量的准确度。

关 键 词:固体推进剂    羽流烟雾    特征提取    透过率    区域识别
