Abstract

The invention particularly discloses a tree detection method. The tree detection method involves a surface acoustic wave device, a laser ranging sensor and a microprocessor, and includes the steps of (1-1), detecting the interior of a trunk by acoustic waves so as to obtain a first reflected acoustic wave signal; (1-2), using the surface acoustic wave device for inputting detected stress waves into the microprocessor so as to obtain a second signal; (1-3), using the microprocessor for computing an output signal-to-noise ratio according to a signal-to-noise ratio computing formula; (1-4), subjecting an output signal-to-noise ratio curve of a system model to stochastic resonance so as to obtain a signal-to-noise ratio valley value of the signal-to-noise ratio curve; (1-5), moving two electrodes of a surface acoustic wave resonator along the circumference direction of the trunk; (1-6), moving the two electrodes of the surface acoustic wave resonator from the start end to the termination end and repeating detection gradually; (1-7), using the microprocessor for establishing a three-dimensional model of the trunk and holes thereof resulting from pest damage. The tree detection method is capable of detecting the positions of the holes precisely so as to determine pest positions, and has the advantages of rapidity in detection and good economy.

Description

technical field [0001] The invention belongs to the field of tree transplanting, digging, felling or branching when a tree transplanting device is inserted into the tree, and in particular relates to a tree detection method. Background technique [0002] The tree pest control methods mainly include trunk whitening method, pesticide burying method, trunk glue coating method, trunk healing method and drug injection method. Among them, the injection method is to drill holes around the trunk and inject the medicine, so that the whole tree has the active ingredients of the pesticide, and no matter where the pests eat on the trunk, they will be poisoned and die. This method is easy to operate, saves labor and has good control effect. But the common injection method can't obtain the specific position where the pest is located, and needs to inject a larger dose of medicine in order to kill the pest, but the large dose of medicine will have a certain impact on the growth of trees. ...
