摘要: 针对目前森林火点定位工作中依靠传统人工瞭望观测方式的不足,研究了一种基于单目视觉的森林火点实时定位方法。首先,提出了适用于森林中着火点具体位置实时确定的几何模型。同时,研究了森林火情监控摄像机视场角的实时计算方法。最后,设计出了基于单目视觉的森林火点实时定位算法并通过试验进行了验证。结果表明,该算法能够满足森林火点实时定位的准确性要求。图5表7参15Abstract: To make up for the defects of the traditional manual observation of fire-point location in forest,a real-time location method based on monocular vision technique for fire-point in forest was studied. A geometrical model suitable for identifying the specific location of fire-point in forest was proposed. Meanwhile,a real-time method,used to calculate the FOV (field of view) of camera for monitoring the fire in the forest,was studied. At last,an algorithm based on monocular vision for this purpose was put forward and proved by experiments. The results of experiments indicated that the algorithm satisfied the precision requirements of the real-time location of fire point in forest.[Ch,5 fig. 7 tab. 15 ref.]
