Granary pest double-viewing angle video collection device and method

Abstract

The invention provides a granary pest double-viewing angle video collection device and method. The video collection device comprises a housing horizontally placed in a granary and a hollow channel formed in the housing, wherein two ends of the hollow channel are symmetrically provided with flared opening channels; the hollow channel communicate with the flared opening channels in a sealing manner;the video collection device further comprises a controller as well LED light sources, a horizontal viewing angle image collector, a vertical viewing angle image collector, a first position detectionsensor, a second position detection sensor and a power supply module used for providing a power supply voltage, which are all connected to the controller. The LED light sources are arranged in the flared opening channels; the horizontal viewing angle image collector and the vertical viewing angle image collector are correspondingly arranged in the periphery of the hollow channel; and the first position detection sensor and the second position detection sensor are arranged in the ports of the hollow channel. The granary pest double-viewing angle video collection device has the advantages of scientific design, high practicability, high precision, convenience in use and long service life.

Description

technical field [0001] The invention relates to the technical field of image collection of granary pests, in particular to a dual-view video collection device and method for granary pests. Background technique [0002] In the process of grain storage, grain loss is affected by many factors, among which the phenomenon of stored grain insects is one of the important factors, and the proportion of grain loss caused by highly harmful stored grain insects is prominent. According to the data released by the State Administration of Grain in 2016, the food loss rate in our country is as high as about 8%. Among them, insect damage is the most serious loss, accounting for 40% to 45%. Taking corn weevil as an example, as a major stored grain pest distributed worldwide, the moth rate is as high as 70%, and the damage is extremely serious. Therefore, the discovery, identification, and prevention of stored grain pests are always an important task in the field of national grain storage, a...

Problems solved by technology

In the trap, in order to attract pests and improve the quality of image collection, the method of adding auxiliary lighting is often used, which increases the chance of trapping pests, and often there will be a variety of stored grain pests and multi-headed stored grain pests mixed in the trap , at the same time, the stored grain pests do not completely crawl and move horizontally in the trap

Therefore, it will cause confusion in the video or image collection results, and it is often impossible to clearly identify the types of stored grain pests. Whether it is computer identification or manual image identification, it will lead to a high misreading rate.
