Embodiment Construction

[0030] In order to better understand the technical problems to be solved by the present invention, the technical means adopted and the technical effects achieved, the specific implementation of the method and system for detecting insect walking tracks of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0031] Such as figure 1 As shown, a method for detecting worm walking tracks includes steps:

[0032] S110. Acquiring frames of images of bugs moving under external environment stimulation;

[0033] S120. Perform grayscale processing on each frame of image to obtain a new frame of image;

[0034] S130. Perform j-level wavelet decomposition on each new frame of image to obtain low-frequency approximate detail components and high-frequency detail components of each layer of each new frame of image, wherein j is greater than or equal to 1;

[0035] S140. Select a frame image from the new frame images after wavelet decomposit...

Abstract

The invention relates to a method and system for detecting the walking locus of an insect. The method automatically acquires the movement image of the insect under external stimulus, performs grey processing on the acquired image, processes the image subjected to the grey processing by using a LOG operator and a wavelet transformation method so as to extract each frame of the insect image, and draw the walking locus of the insect according to each frame of the insect image. The method and the system may rapidly, repeatedly, and automatically observe and draw marks of the walking locus of the insect under external stimulus, thereby relieving the burden of technicians and providing a modern auxiliary tool for crop protection and research. The drawn walking locus of the insect is accurate and is beneficial to the subsequent research of the technicians.

Description

technical field [0001] The invention relates to the technical field of video image processing, in particular to a method for detecting an insect walking track and a system for detecting an insect walking track. Background technique [0002] In the field of plant protection, it is often necessary to conduct tracking research and analysis on the trajectories of pests stimulated by external factors (such as pesticide application, incentives, etc.). Traditionally, the trajectories of pests under the stimulation of external factors are realized manually, that is, manually observing the trajectories of pests under external stimuli, and then manually drawing the trajectories of insects according to the observation results. This method is time-consuming and labor-intensive, and the obtained walking trajectory of the insects under external stimuli is not accurate enough, which affects the follow-up research of relevant technical personnel. Contents of the invention [0003] Based ...
