Method, device, system and computer readable medium for rapidly detecting pest egg in grain based on pest egg and pest hole structure features

Abstract

A method, device, system and computer-readable medium for rapidly detecting a pest egg in a grain based on a pest egg structure feature and a pest hole structure feature is disclosed. The detecting method includes acquiring a gray digital image of a grain pile and three-dimensionally reconstructing it to obtain a three-dimensional image of a multi-grain pile; segmenting the three-dimensional image of the multi-grain pile to obtain one or more grains-contained unit images; identifying pest hole areas in each of one or more grains-contained unit images based on a biological feature of a pest; determining whether the pest hole area is a pest egg area based on the pest hole structure feature; and determining whether an alive pest egg exists in the pest egg area based on a geometric feature and a physical feature of the pest egg.
