Abstract
In this paper, image segmentation technique using color information was introduced to extract bullet region and finally obtain bullet motion parameters. This method differs from previous processing method with gray information. Utilizing color hue component difference to extract every bullet region and using morphological operation to smooth edge of regions are two main processes of this method. Edge of bullet region is finally traced with Freeman chaincode. Chaincode is used to recognize regions and used in following neutral axis fitting. Velocity and acceleration of bullet can be obtained when the gravity center of each bullet region is achieved. Least Square Method is used to fit neutral axis of bullet image with contour data, accordingly the elevation angle of bullet at each moment can be got.
