A Blur Restoration Research on Sequential Images of Bullets Taken in the Penetration Test

摘要

In order to remove the motion blur in sequential images of bullets taken in the penetration test, firstly we found out the relationship among the degradation model, direction of motion and blurred length of a bullet image in this paper. Then the radon transformation was used to found out the direction of motion. At the same time, the blurred length was got by using differential autocorrelation method. Finally, we accomplished the restoration of the bullet by using the constrained least squares filter. The result shows that the method taken in this paper is simple and feasible. And the result of the restoration is very satisfying.
