Region Target Imaging Task Scheduling Method Based on Approximation Algorithm for Optical Remote Sensing Satellite
摘要
Abstract
Most of the imaging task scheduling study objects of optical remote sensing satellite are based on point target.For region target,most of the researches convert them to point target,which has disadvantages of low-precision and low-efficiency.Additionally,solving the problems of long-period scheduling is time-consuming,and large-area and long-period imaging task scheduling is compared with poor performance.In this paper,imaging task scheduling model is built according to constrain conditions,and optical remote sensing satellite orbit and the track of sub-satellite points are induced and analyzed.The projection of track of sub-satellite points is approximately considered as straight line.The model is solved through region target projected to a line,two-dimension surface region converted to one-dimension linear region.The complexity of solving region target problems is reduced significantly.The side swing is handled in one-dimension linear region,and the performance of solving long-period scheduling problem is improved at the same time.The verification results of HJ-1A satellite show that method presented in this paper can solve the large-area and long-period imaging task scheduling problem in a short time.关键词
