Study on dual-stream fusion gray value discrimination method for maritime crashed aircraft based on time difference accumulation optimization

Abstract： In response to the problems existing in the detection of maritime crashed aircraft targets, such as insufficient background noise suppression, incomplete target contours, weakened target features, and difficulty in identifying small target pixels, a dual-stream fusion gray value discrimination algorithm based on time difference accumulation optimization is proposed. By constructing a three-dimensional optimization of "dual-target feature enhancement-noise suppression-spatiotemporal registration", a five-level progressive image processing is realized. An airborne platform image acquisition and evaluation system under typical scenarios is built; "day-night" stepwise experiments are conducted, and it is found that the maximum dual-target signal ratio in daytime experiments can reach 1.739, and the signal-to-background ratio in nighttime environments can reach 25.
