基于视频图像分析的推进剂羽流烟雾透过率测量技术
Research on Measurement Technology of Plume-smoke Transmittance of Solid Propellant Based on Video Image Analysis
摘要
Abstract
In order to dynamically measure the light transmittance of plumesmoke distributed in a large space , a video-image test system for solid propellant plume-smoke shielding ability was established. The measuring images and the background images were processed to obtain the contrast of the measured image, and the measurement results of the neutral optical attenuator calibrate and convert into the transmittance. The test system was established according to the measurement model and the verification test was performed. The results show that the video image measurement method has a larger measurement field of view, it can obtain more information on smoke distribution etc., and can reduce the interference of the light radiation of environmental background. The data obtained from this method has good repeatability and good system stability, this method can be used for accurate measurement of the plume-smoke light transmittance of propellant.关键词
