Extraction method for target movement information based on single remote sensing image

Abstract

The invention relates to an extraction method for target movement information based on a single remote sensing image. The extraction method comprise the following steps of (1) laying a plurality of linear array imaging sensors or multiband planar array imaging sensors on the same optical remote sensor imaging surface, and acquiring pattern parameters of the above imaging sensors; (2) acquiring temporal and spatial parameters of imaging the remote sensing images by a remote sensing imaging controller, a remote sensing platform position measurement sensor and a remote sensing platform attitude measurement sensor; (3) acquiring single remote sensing image data of the same target object by registration synthesis of the remote sensing images; and (4) extracting target characteristics of the acquired single remote sensing image, determining a scanning line of the target, and solving the movement information of the target object according to tiny time-space shift characteristics (i.e. space shift parameters and time shift parameters) of the moving target object on pixels of the imaging sensing sensors. The extraction method can be widely applied in the fields such as large-scale remote sensing application, traffic status monitoring, target movement information extraction, etc.
