[0029] The present invention will be described in more detail below in conjunction with the drawings:
[0030] Such as figure 1 As shown, the specific implementation of the present invention is as follows:
[0031] Step 1: High-orbit satellite image detection and tracking of maritime targets
[0032] For the high-orbit satellite image sequence, the coastline data is used for geographic correction, the classic constant false alarm algorithm is used for target detection after the image registration between frames, and the geometric model of satellite optical imaging is used, that is, the transformation relationship between the image side and the object side of the image Convert the position of the target into a geographic location, perform the motion modeling of the target under geographic coordinates, use multi-frame data association in multi-hypothesis tracking to further reduce false targets, use filtering algorithms to estimate the motion state of the target, and obtain the motion ...
