Abstract: Objective To explore a method of forensic identification work in the non-linear length of the plane. Methods 10 soldering tin wires with different lengths were cut out accurately and the results were read as a control (direct reading method of steel ruler). Then the ten soldering tin wires with different lengths were randomly bent and then calculated by the method studied in this paper The length as a Pixel group, and two sets of data for statistical analysis. Results The difference between the results obtained by the Pixel method and those directly read by the ruler direct reading method was not statistically significant. Conclusion The Pixel method has obvious advantages over the traditional cotton method in measuring the non-linear length of the plane (such as scars and wounds). The calculated length is more accurate and easy to operate, making the forensic identification more accurate and convincing Adapt to the requirements of litigation, forensic identification in the good prospects.
