Infrared weak and small target energy accumulation method based on multi-dimensional motion parameters

The invention relates to an infrared weak and small target energy accumulation method based on multi-dimensional motion parameters, and the method comprises the steps: obtaining all possible motion parameters of a target through building a multi-dimensional motion model of the target, obtaining a target motion track in a multi-frame image, and carrying out the signal-to-noise ratio improvement of a weak and small target in the image through employing an energy accumulation method, the method comprises the steps of obtaining an image set after energy accumulation, performing mean value calculation on the image set, realizing effective accumulation of target energy, performing constant false alarm judgment on images, filtering out images with low signal-to-noise ratio, obtaining an image set after signal-to-noise ratio improvement, and finally performing quantitative calculation on the signal-to-noise ratio of the image set after energy accumulation to obtain a final signal-to-noise ratio improvement amplitude.
