The flame image signal absorbed by the camera will be sent to the image supervision system, then it will be real-time displayed after being processed by D/A and the reduced video data will be saved.

摄像头将摄取的火焰图像信号送入图像监控系统，经D/A处理后实时显示并将压缩视频数据存储。

The image processing method was introduced into the experiments. Flame height was acquired by the video frequency taken by the camera to give the parameters of lateral critical water flow rate.

将数字图像处理方法运用到实验中，通过读取摄像机拍摄的杉木板垂直火蔓延的视频，实时获取火焰高度，为后续计算临界水施加率提供参数。
