Embodiment Construction
[0022] The technical methods in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0023] refer to figure 2 , figure 2 It is a schematic diagram of the remote sensing satellite covering an irregular area in an area-array staring optical remote sensing satellite area coverage imaging path optimization method of the present invention. The problem of continuous coverage of irregular areas by satellites can be transformed into a path optimization problem for traversal of discrete points in the center of multiple squares, which can be solved by an optimization algorithm to calculate the minimum number of squares and the s...

The technical proposal of the invention is to provide a method for optimizing an area coverage imaging path of an area array staring optical remote sensing satellite, comprising the following steps: the remote sensing satellite optimizes the imaging times covered by the coverage area to obtain the optimized imaging times; The pose stepping path of the coverage area is optimized by remote sensing satellite in order to obtain the optimized traversal path. Remote sensing satellites use optimized imaging times and convenient paths to cover the coverage area. As that continuous coverage problem ofthe satellite to the irregular region is convert into the path optimization problem of the discrete point traversal, the number and the path of the satellite image for the irregular region are determined by solving the optimization algorithm, and the efficiency of the satellite imaging coverage to the irregular region is effectively improved. The invention is characterized in that the continuous coverage problem of the satellite to the irregular region is converted into the path optimization problem of the discrete point traversal. The method and algorithm provided by the invention can be usedfor formulating an irregular area coverage scheme and satellite mission planning of a gaze-type optical remote sensing satellite such as 'Gaofen-4'.
Description
technical field [0001] The invention belongs to the field of satellite remote sensing applications, in particular to an area-array staring type optical remote sensing satellite area coverage imaging path optimization method. Background technique [0002] Area staring optical remote sensing satellites mainly refer to optical remote sensing satellites that use large area array CCD or CMOS visible light area array sensors and large area array infrared sensors as image acquisition means. Coverage imaging of a large area of the Earth's surface can be achieved through satellite attitude maneuvering. With the development and application of geostationary orbit observation methods, geostationary satellites have been put into operation at home and abroad, especially the Gaofen-4 satellite, which was launched in December 2015 and is in orbit. A new level of application in the field of geostationary orbit earth observation, it has a world-leading position in the scale and resolution ...
