| Abstract: | A track acquisition algorithm of dim target in serial star images of moving background is proposed.Originally,an algorithm named cross projection is used to identify the area of background star and targets.Then,a movement parameter estimation method based on particle image velocimetry(PIV) is provided.Finally,a target track acquisition method is proposed.The simulation experiment is done with two small targets in 16 frame serial star images.Results show that the algorithm can detect both the track of dim ta... |
