摘要

针对传统乙烯气体泄漏检测和定位方法存在效率低、检测范围小和实时性差等问题，提出了一种基于红外成像的泄漏检测方法。该方法利用红外摄像机获取乙烯生产车间内各设备工作时的红外视频图像，将其转化为灰度图像序列后，利用逻辑运算融合多幅帧间差分和背景差分后的图像信息，并利用形态学滤波消除噪声干扰，最终获得气体泄漏疑似区域的准确位置。实验结果表明，该方法高效、准确且具备实时性，能够获得完整、清晰的泄漏疑似区域，实现了无色气体泄露区域的初步定位。

Abstract

Becasue the traditional ethylene gas leak detection and localization method has the problem of low efficiency

small detection area and poor real-time performance

a leakage detection method based on infrared imaging was proposed. The method uses infrared camera to acquire infrared video image of ethylene production workshop when equipments are working

and converts it to grayscale image sequence. The image information after multi frame diffe rence and background difference was cumulated together through the use of logic operation

and noise interference was eliminated through morphological filtering. At last

the accurate position of suspected gas leak area was obtained. The experimental results indicate that this method is efficient

accurate and real-time

and can obtain a complete

clear leakage suspected areas.The purpose of preliminary localization of the colorless gas leakage area has been achieved.
