A novel automatic recognition system for bullet marks is developed. A new micro constant force displacement sensor with micro and constant measurement force is introduced. It can realize the measurement of bullet marks without damage on the surface of sample bullets. Based on the improved wavelet analysis technology, the signals that reflect the stable characters of the guns that fire the sample bullets are extracted exactly without boundary errors and can be analyzed on multi scalar. A novel multi scalar correlation analysis technology that can use the information of multiple frequent segments is adopted and obtained at a very high identification rate.
