Algorithm research in high-speed object parameter validation of exterior trajectory

A novel method based on the principle of optical imaging for measurement in the high-speed target paprameter of exterior trajectory is presented.The techniques of demarcating the trajectory by equal time,rotating inside the fixed time and validating velocity parameters through the picture at each corresponding time-dot are combined to confirm the speed parameters of high-speed moving target in shooting range rail.An algorithm is derived from the length of the given trajectory.The MCU controlling technology is utilized to track the target by applying the algorithm.The speed parameters obtained are validated by the data gathered from the photoelectric angel-position sensor AC36 and the corresponding pictures.The method proposed is evaluated in a shooting range,the error rate is less than 1%.
