摘　　要：研究火灾中火焰运动方向估计问题。针对火灾现场,燃烧中的火焰存在着动态特征不定,运动方向容易发生随机性改变,影响估计的准确性。传统的物体运动方向估计方法很难对燃烧的火焰做出准确的方向估计。为解决上述问题,提出基于运动能量块计算的火焰运动方向判定方法,首先为燃烧的火焰建立运动能量块,创立火焰的动态特性,通过预判火焰运动块的方向,形成运动块在各个方向上的匹配,完成对火焰燃烧过程中,运动方向的准确估计。仿真结果证明,改进方法能对燃烧中的火焰运动方向做出准确估计,取得了满意的效果。Research in motion direction fire flames estimation.According to the scene of the burning fire flame of dynamic characteristics are uncertain.The directions are prone to change,and it is difficult for traditional direction estimation method with the burning fire to accurately estimate direction.To solve the problem,the flame determination method based on movement of energy calculation was proposed.First,the e movement of energy was established for the burning flams,the dynamic characteristics were founded through the flame anticipation of flame movement direction,the matching of the flame process was completed,and the direction of motion accurate was estimated.Simulation results show that the method can make accurate estimate of the movement direction of combustion flame and achieve satisfactory results.
