Three-dimensional multispectral insect distinguishing device and identifying method thereof

Abstract

The present invention discloses a three-dimensional multispectral insect distinguishing device and an identifying method thereof. The three-dimensional multispectral insect distinguishing device includes: a handheld probe, which is provided with a first camera, a second camera, a first video interface, a second video interface, a white-light source, an LED light, a first switch, a control module, and a battery; and dual-channel video glasses. The three-dimensional multispectral insect distinguishing device further includes a processing apparatus used obtain a disparity spectrum between the insect and a near infrared reflectivity spectrum of the visible light of the background object according to the insect and the near infrared reflectivity spectrum of the visible light of the background object, to get the wavelength of a preset scope of the peak value of the disparity spectrum. Upon inspection, the tested object is illuminated by the ray of light within the maximum disparity spectrum scope output by the LED light, to enhance the contrast between the insect and the background, which greatly improves the positive rate of the insect. In addition, a three-dimensional image is generated by the dual-channel video glasses, which may reduce confusion between planar plaque or cavity and three-dimensional objects, thereby further increasing the positive rate of the insect.

Description

technical field [0001] The invention relates to the technical field of insect identification, in particular to a three-dimensional multi-spectral insect identification device and an identification method thereof. Background technique [0002] In the daily entry-exit plant quarantine work, it is often necessary to inspect the goods, find and capture the pests in them, and prevent the pests from being introduced into the country along with the goods and means of transportation, causing huge losses in agriculture and forestry. [0003] Because many pests have protective colors, the body color of the insects is similar to that of the cargo under ordinary white light, or the mottled color of the insect body is easily confused with the mottled color of the cargo, making it difficult for the pests to be found. At present, during the inspection, the goods in the open position are illuminated by sunlight or lights, and the goods in the closed position are illuminated by flashlights. ...

[0003] Because many pests have protective colors, the body color of the insects is similar to that of the cargo under ordinary white light, or the mottled color of the insect body is easily confused with the mottled color of the cargo, making it difficult for the pests to be found

At present, during the inspection, the goods in the open position are illuminated by sunlight or lights, and the goods in the closed position are illuminated by flashlights. The light used is all white light, which is interfered by the confusion factors of insects and background, and the detection rate of pests cannot be improved.
