Abstract

The invention discloses a watershed algorithm-based insect body identification counting method and system, and belongs to the technical field of image processing. The method comprises the following steps: collecting an image containing insect bodies, and carrying out binarization processing to obtain a binary image; deleting the outline with the area smaller than the minimum insect body area in the binary image, and filling the outline of the insect body to obtain a filled image; gradually corroding the filled image, marking all insect body contours, and expanding the marked background to obtain a first marked graph; further processing the filled image and the first mark graph by using a watershed algorithm to obtain a second mark graph; and obtaining the contour roundness and the contourarea in the second mark graph, and counting the number of contours to complete counting. Compared with a traditional manual counting mode for counting the number of the insect bodies, the method can automatically count the number of the insect bodies, is higher in efficiency and recognition counting accuracy, and is suitable for counting various insect pests.

Description

technical field [0001] The invention belongs to the technical field of image processing, and more particularly relates to a method and system for identifying and counting insects based on a watershed algorithm. Background technique [0002] In our country, the annual loss of crops caused by pests and diseases is quite alarming. Therefore, the prevention and control of crop diseases and insect pests is of great significance to ensure the development of the national economy. [0003] Taking the tobacco industry as an example, tobacco insects are the main pests in my country's tobacco industry. In the entire tobacco circulation and production process, from tobacco leaf purchase to leaf threshing and re-baking, storage and transportation, production and processing, finished product storage, transportation and sales, there are May be harmed by smoke insects. The trap is an important tool for monitoring tobacco insects. This trap consists of a cardboard coated with glue and a trap...
