Abstract

In view of difficult acquisition of high speed armature in electromagnetic propulsion device outside ballistic, in this paper, a high-speed photography collection system was designed for record and analysis under external ballistic firing conditions, and the armature image sequences were collected respectively under low and high speed successfully. ISODATA algorithm was used innovatively to segment the collected image for accurate trajectory data. Through experimental comparison, results show that the algorithm is simple and easy to use, improving the accuracy of parameter measurement.

Key words： high speed photography; external trajectory; image segmentation; ISODATA algorithm
