Abstract: Electro-optic theodolite is one of the most important measurement.Electro-optic theodolite is intuitionistic and high precision.Electro-optic theodolite is applied to get ballistic trajectory parameter.Electro-optic image interpretation gets and analyzes the original image to give the ballistic trajectory data.This paper provides a method of image interpretation.This method makes use of the information of last time to modify probability matrix of the target’s position.Therefore it reduces the area of image process and impoves the efficiency of arithmetic.

摘要: 光电经纬仪是武器靶场最为重要的测量手段之一,具有直观性强、测量精度高等特点,是获得导弹外弹道参数主要途径。光测图像判读系统获取空中目标运动过程的原始图像和有关数据的原始记录,通过事后判读分析,可获取精确的弹道测量数据。研究了基于马尔科夫链的图像判读方法,该方法通过利用上一时刻的判读信息不断修正目标位置的概率分布矩阵,从而降低图像自动化处理的区域,提高了算法效率,降低了算法的复杂度。
