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.
