Interpretation of target attitude based on optical image
-
摘要: 采用摄像测量方法获取目标的飞行姿态是目前靶场主要测量手段之一。目标姿态可以用目标轴线在空间的方位来描述，即姿态的判读处理就是要提取线的空间位置。在进行图像判读处理时除采用传统的基于点的判读处理手段外，还应根据不同的目标类型采用不同的判读处理方法，文中给出了基于首尾两点的判读处理、基于线的判读处理和基于模型的三种判读处理方法，有效解决了不同类型目标的判读处理问题。Abstract: Photography measurement can be used for measuring target flight attitude in test field. Since the target attitude is described by its axis orientation in space, its interpretation can be achieved by obtaining the axis orientation of the target. For the image interpretation, different methods should be adopted to different types of targets. This paper presents three methods for image interpretation: the interpretation based on head-tail spots, the line-based interpretation, and the model-based interpretation.The interpretations of different targets are achieved effectively.
