Litchi pest monitoring and identifying system and method

Abstract

The invention relates to a litchi pest monitoring and identifying system and a litchi pest monitoring and identifying method. A pest recognition module, a matching judgment module and a pest feature database accommodating texture, color, contour and background feature libraries are arranged in a computer server of the system. And the matching judgment module transmits a matching judgment result tothe mobile phone of the user. The monitoring and identifying method comprises the following steps: firstly, establishing a pest identifying module, and carrying out image processing on a picture shotby a user to obtain texture, color, outline and background feature maps; feature values of the four feature maps are extracted respectively and simplified into fingerprints of character strings, andthe fingerprints are sent to a pest feature database. Then real-time monitoring is carried out, a user shoots pest photos in real time, four characteristic fingerprints are obtained through processingaccording to the same method of database building, the fingerprints correspond to the fingerprints stored in the pest characteristic database, and the pest with the maximum matching degree is the possible pest. According to the method, litchi pests are recognized, control measures are taken in time, the yield and quality of litchis are guaranteed, and the database can be continuously perfected and enriched and is convenient to use.

Description

technical field [0001] The invention relates to the field of agricultural pest control, in particular to a litchi pest monitoring and identification system and a monitoring and identification method. Background technique [0002] Litchi is currently one of the most popular fruits, with high sales across the country. During the planting process of litchi, it is easy to be attacked by diseases and insect pests, resulting in the decline of yield and quality of litchi, so it is very important for the prevention and control of litchi diseases and insect pests. At present, the means of controlling litchi pests at home and abroad are still comprehensive control based on chemical control. Excessive use of chemical pesticides will cause a series of serious problems such as damage to the ecosystem of litchi orchards, increased resistance of pests, decline in fruit quality, and environmental pollution. . It is necessary to choose the appropriate amount of pesticides according to the ...

Problems solved by technology

[0004] The existing monitoring and early warning system for farmland diseases and insect pests has problems such as narrow application range, difficulty in expansion, and high product cost. It is rarely applied to extensive field crops such as litchi. The unique litchi pest monitoring and identification system is of great significance to improve the pest control level of litchi
