Because current image and 3D scanning file processing technologies are difficult to use in comparing cable-cutting toolmarks effectively, an airport cable-cutting toolmark rapid-tracing matching algorithm based on single-point laser sensing is presented. The proposed algorithm applies a boxplot to the linear toolmark signals picked by a laser displacement sensor to perform an abnormal data correction. Then, a rotation angle adaptive correction is performed to unify the matching data. Furthermore, in multimatching strategies based on a threshold sequence, the difference in variance is used to perform the similarity matching of toolmark features. Finally, a correct determination of the corresponding tools is rapidly achieved. The practicality and effectiveness of the proposed algorithm are verified by experiments using actual mark inference cable-cutting tools.
