A Measuring Method of Attitude Angle Based on Linear CCD for Spatial Object

摘要

It's very difficult to meet the requirement of real-time measurement by the traditional ways mostly based on the static and quasi-static measurement. With the three subsystems for 3D coordinate reconstruction of spatial point target. this paper realized the real-time measurement for the measured object's attitude angle by separate real-time capturing three spot cooperation targets placed on the measured object and the spatial solution. The quantity and distribution of the spot cooperation targets and the relations according with each other between them and many camera optical systems were demonstrated. The mathematical model of the attitude measurement was established. Finally this method was confirmed by an experiment. This measuring method can be widely applied to measure the movement object's attitude angle in the certain spatial scope.
