Abstract
For the optical sensor being occluded by the parts on satellite,this paper proposes a method of occlusion analysis of satellite optical sensor using STL(Stereo Lithographic)models. First,three﹣dimensional model of the part on satellite is transformed into STL grid model files. And the STL grid data of part on satellite are extracted.Then the STL grid coordinator data of part on satellite and the view field of optical sensor are processed into angle data.Then the angle data of part on satellite and the view field of optical sensor are compared.Finally,the occlusion of optical sensor by part on satellite is analyzed.The pictures of the occlusion view field are plotted and the occlusion rate is computed.Compared with previous methods,this method improves the efficiency at work and it is easy to use in engineering design.It is an effective means for the occlu﹣sion analysis of the optical sensor view field on satellite.关键词
