Research on infrared small target detection technology based on 3D filtering

Abstract

To improve the detection effect of frame difference method on low SNR target in complex environment，in this paper, based on the principle that moving targets have continuity in time, the tracking algorithm before detection is used to accurately screen targets through the design combining 3d filtering preprocessing and target trajectory judgment, so as to achieve the effect of reducing false alarm on the premise of maintaining a high detection rate, which is of significant significance for dim small targets detection.
