Problems solved by technology

[0007] Computer vision disease, insect pest and weed monitoring technology is still in the early stage of development. It has not been used for a long time in agricultural application scenarios, and the training data is small and the classification is not balanced, resulting in a high recognition rate of the model self-test, but in actual application scenarios, the actual recognition rate is low.
Traditional hyperspectral pest identification requires the use of hyperspectral data, which is inconvenient to obtain and not very applicable
The current identification of diseases and insect pests is mostly based on the classification of pictures. It is impossible to accurately determine the location of disease and insect pests, and it is impossible to detect multiple diseases on the same plant at the same time.

Abstract

The invention relates to a method and system for detecting crop diseases and insect pests based on computer vision, and belongs to the technical field of computer applications. The method includes: S1: obtaining a picture of a crop, inputting the picture of the crop into a pre-classification model, identifying a picture of a crop that has suffered from diseases and insect pests, and using it as a target picture to be detected; S2: inputting the target picture to be detected The detection model performs detection to obtain a target detection result; S3: Output the target detection result, where the target detection result includes the type of pests and diseases and the locations where the pests occur in the target picture. The invention effectively improves the detection efficiency of pests and diseases, shortens the discovery time of pests and diseases, and reduces the planting risk of growers.

Description

technical field [0001] The invention belongs to the technical field of computer applications, in particular to a method and system for detecting crop diseases and insect pests based on computer vision. Background technique [0002] Computer vision refers to the machine vision that uses cameras and computers instead of human eyes to identify, track and measure targets, and further image processing, using computer processing to become images that are more suitable for human eyes to observe or transmit to instruments for detection. ; Computer vision is widely used in various fields, such as manufacturing, inspection, document analysis, medical diagnosis, and an integral part of various intelligent / autonomous systems in the military and other fields. [0003] The traditional detection of crop diseases and insect pests is time-consuming and complicated, and is usually limited to offline analysis in the laboratory. In 2016, Zhejiang University used hyperspectral imaging technolog...
