【摘要】 本论文在学习和研究现有的多种空间物体三维信息测量的成熟技术的基础上,根据光学的原理如空间点光源的夫琅和费衍射现象和光在传播过程中的能量分布原理,参照近代和现代多种天文望远镜中利用光衍射规律进行高精度二维分辨的技术,提出了“高分辨率三维测量”、“三维相对运动轨迹跟踪”以及“三维相对运动轨迹预报”等三种利用光学基本现象和统计学原理并结合数字图象处理的应用技术方案和算法,并通过实验结果初步验证了其可行性。 这种空间物体三维信息测量技术可以广泛的应用于航空航天、遥测遥感、天文观测、机器人技术、生物医学以及国防军事等诸多领域,具有较高的研究价值和实用价值。

【Abstract】 In this thesis, on the basis of the study and research of some three-dimensional optical measurement methods nowadays, a method of three-dimensional optical measurement using statistics technology based on the theory of F.H. hole diffraction and energy distribution of light transmitting on the way is introduced. The technology of digital image processing is used in this method. At last, a method of stracing and forecasting the three-dimensional trace of a dot light source using the theory of least squares and the theory of Kalman filtering is intruduced and its feasibility is tested by experiment.This method can be applicable for the fields such as astronomy, space navigation, national defense and all fields in which the high speed and real time 3 dimensional measurement is needed.
