A night firing system by one camera equipped convex mirror for monitoring tracer bullet to teach exercises

In general, an ordinary CCTV camera has equipped 24 frames per second. This camera is not capable to get a image of bullet trace which has a speed about 1km per second. In spite of the difficulties, by means of the stereographical projection, a long distance trace is able to be contained in one image. Currently almost every camera used a skill of great many frames per second or devices equipped electrical tools of time difference operation for getting high speed object image. In this paper we propose s single camera system equipped convex mirror for monitoring trace bullet to teach night firing exercises. We show this camera is useful to determine the bullet goes right to target or not.
