探测概率、虚警概率是衡量红外搜索跟踪系统性能的重要指标,其大小由系统硬件水平、检测算法设计等因素决定。通过分析影响红外搜索跟踪系统探测概率、虚警概率的因素,建立了管道检测与探测概率、虚警概率关系模型,研究了序列图像检测中管道检测对系统探测概率、虚警概率的影响。通过仿真分析了实验结果,系统总检测概率与总虚警概率分别随单帧检测概率与单帧虚警概率的增加而增加,在管道长度相同的情况下,总检测概率和总虚警率都将随需检测帧数的增大而减小。
Detection probability, false alarm probability is an important index to measure the performance of infrared search and tracking system. Its size is determined by system hardware level and detection algorithm design. By analyzing the factors that affect the probabilities of detection and false alarm of infrared search and tracking system, the relationship model between probability of detection and detection and the probability of false alarm was established and the influence of pipeline inspection on the detection probability and false alarm probability was studied. Through simulation analysis of the experimental results, the total detection probability and the total false alarm probability increase with the single-frame detection probability and the single-frame false alarm probability respectively. Under the condition of the same pipe length, the total detection probability and the total false alarm rate are both Will be detected with the increase in the number of frames decreases.
