摘　　要：低信噪比条件下序列图像中微弱点状运动目标的检测是许多实时监视系统的关键算法,具有信息量大、目标轨迹组合复杂和实时处理难度大等特点。为有效检测出微弱点目标,提出了一种基于最大值投影与目标轨迹关联相结合的运动点目标检测算法,仿真试验表明该算法具有较好的检测性能,可有效地检测出低信噪比条件下图像序列中的运动点目标,同时也可检测出交叉运动的多个点目标。The detection of dim point moving target in low SNR image sequence is the key algorithm in many real-time surveillance systems,which has such characteristics as large amount of information,complicated combination of target trajectories and difficult real-time processing.For effectively detecting dim point target,a new point target detection algorithm based on constructing combined-image and sequence-image is presented in this paper.The experiment shows that the algorithm has better detection performance,it can detect dim point moving target in low SNR image sequence,also detect multiple point targets which move across each other.
