摘　　要：为降低视频烟雾检测中的虚警率和提升检测效率,提出Y^(d)U^(a)V^(a)颜色模型,该模型可以表征烟雾的空间域分布特性和时间域变化特性。利用该颜色模型快速筛选出疑似烟雾图像块,降低虚警率和提升运算效率。提出改进的MobileNetV3网络结构,用于提取图像深度特征并对疑似烟雾图像块进行分类识别,检测视频中是否存在烟雾。视频烟雾检测仿真结果表明:该方法准确率和检测帧率高,虚警率低。In order to reduce the false alarm rate and improve the detection efficiency for video smoke detection,the Y^(d)U^(a)V^(a) color model was proposed,which can characterize the spatial distribution and temporal variation of smoke.By using this color model to quickly screen the suspected smoke image blocks,the false alarm rate was reduced and the computing efficiency was improved.An improved MobileNetV3 network structure was proposed,which is aimed to extract deep features of images and to classify the suspected smoke image blocks so as to detect whether there is smoke in a video.The simulation results of video smoke detection show that this method has high accuracy,high detection frame rate,and low false alarm rate.
