Abstract

The invention discloses a forest theft behavior identification method and belongs to the information processing field. The method is characterized by: using a SOFM method to carry out subclass analysis on an audio signal so as to determine whether the audio signal is a forest theft behavior; using a SVM method to establish two classifiers so as to identify the forest stealing behavior and furtherdividing the type of the forest stealing behavior into a felling behavior, a sawing behavior and the other behavior; using the SVM method to establish one classifier so as to identify the forest poaching behavior and further dividing the type of the forest poaching behavior into a shooting behavior and the other behavior; calculating a sound source direction angle of the audio signal through using a microprocessor so as to determine a direction of the forest theft behavior.

Description

technical field [0001] The invention relates to a forest theft prevention method, in particular to a forest theft behavior identification method. Background technique [0002] Forest theft refers to the prevention of man-made forest robbery and poaching, which is an important field of forest ecological security protection. Driven by economic interests and weak legal awareness, forest theft cases occur from time to time, which is one of the important hidden dangers of forest ecological security. At present, forest theft mainly relies on manual patrolling, and there is no information-based solution available to monitor and warn against forest piracy. [0003] In addition, the rangers cannot predict the type of forest theft and cannot make corresponding preparations for the forest theft. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a method for identifying forest theft, which can accurately determine whether the audio signal is forest...
