Abstract: A new technology of real-time detection on infrared dim moving point targets in image sequences is studied. Through speed and direction of small target, useless trajectories is cut, which reduces calculation amount and calculation time greatly. The technology based on multistage hypothesis test which detects the dim moving point targets and delete the trajectories of noises is used. It gets the targets more accurate. Experimental results show that the technology requires less calculation and has good real-time performance.

Key words: 3D spatial-temporal, real-time performance, moving message of target, point target detection
