Measurement of effective distance for the fuze based on the camera shooting in the rear
The measurement method for shooting in the rear using single camera and intersection measurement on plane using two cameras were presented in order to solve the problem of small field coverage for shooting orthogonally using the camera in the test of effective distance for the grenade fuze. The distance of the exploded bullets in the X direction and the quantitative denotation of the error due to the spread of the projectile in the Z direction were obtained for the single camera, and the position of the exploded bullets, were obtained accurately in the X direction and in the Z direction for intersection measurement using two cameras on two-dimension plane. First, the measurement formula was deduced, and the error due to the spread of the projectile in the Z direction for the single camera was analyzed, then, the intersection measurement method using two cameras on plane was validated by the experiment, the results show that the absolute error are less than 6cm.
