图像型火灾探测中消防炮定位技术研究摘要随着大空间火灾探测技术的研究，传统的消防已经不适用于大空间的灭火，为了克服传统灭火系统的不足，在此基础上本文提出了利用高压水炮进行定点灭火的技术。论文是在系统已经实现火灾探测的基础上提出的高压水炮空间定位技术，即在发生火灾的情况下，在对火灾各种特征进行了提取和干扰的排除后，利用计算机计算火灾的空间位置。本文提出的定位算法具有定位准确、识别性较高、计算速度快、实时性较高等特点。论文结合计算机图形学、数字图像处理、计算机视觉等技术，将摄像头采集的火灾火源的图像经过相应的变换，转换成实际的世界坐标，并结合高压水炮和摄像机各参数，直接计算出高压水炮的定位参数。关键字：火灾探测；计算机视觉；高压水炮定位ImageTypeFireDetectionSystemofWaterCannonPositioningTechnologyResearchAbstractWiththelargespaceoffiredetectiontechnologyresearch,thetraditionalfirehasnotusedforlargespaceoffire.Inordertoovercomethedeficiencyoftraditionalfire-extinguishingsystems,onthebasisofthisproposedusingwatercannonfireonthedot.Insystemhasachievedfiredetectionisproposedonthebasisofthewatercannonspacepositioningtechnologies.Alsointhecasesoffire,afterinvariouscharacteristicsoffireandeliminationofinterference,usingthecomputercalculationoffireinspace.Inthispaperthepositioningalgorithmhasaccuratepositioning,identificationandcomputingspeedandhighperformancecharacteristicsandsoon.Thispaperbasedoncomputergraphics,digitalimageprocessingtechnology,computervision,etc.Thecameraimageacquisitionoffiresourcethroughthecorrespondingtransformation.Converttheactualworldcoordinatesandcombinedwithwatercannonandcameraparameters.Italsocancalculatewatercannonpositioningparameters.Keywords:Firedetection;Computervision;Watercannonposition目录1.绪论....................................................................................................51.1引言..........................................................................................51.2研究背景和意义......................................................................61.2.1传统火灾探测技术的不足............................................61.2.2图像型火灾检测技术的提出........................................71.2.3国内外研究现状.............................................................72.图像型火灾探测.............................................................................102.1概述........................................................................................102.2原理介绍................................................................................102.3火灾图像处理系统的硬件组成............................................112.4火灾图像的获取....................................................................122.5火灾图像的分割处理............................................................132.5.1区域生长法分割图像..................................................132.5.2阈值选取算法...............................................................132.6火灾图像的仿真处................................................................152.6.1图像预处理..................................................................152.6.2图像分割与特征提取..................................................182.6.3灰度阈值分析..............................................................193基于计算机视觉的高压水炮定位的研究......................................203.1计算机视觉...............................................................................
