Abstract
An imaging method using sequential screen-spot images generated by close-range optical tracking is proposed for test bed measurement of 3-D aircraft attitude parameters. With this method, laser emitters installed on the skin of an aircraft cast laser spots on stationary screens. First, a laser tracker is used to globally calibrate multi-directional high-speed cameras and the fixed screens, establishing a transform relationship between the various coordinates. Then the cameras shoot and store changes in the spots' positions as changes of aircraft attitude are reflected on the screens. Finally, the image sequences are analyzed to determine the aircraft's attitude parameters. This method eliminates loss of data due to overexposure of image sequences caused by flames from propulsion; moreover it increases the effect of changes in aircraft attitude so that total measurement accuracy improves substantially. Our experimental results indicated that errors in this method are not more than 0.03° within the measurable range of rotation.
