Fruit tree pest recognition method and system based on image recognition

The invention discloses a fruit tree pest recognition method and system based on image recognition. The method comprises the following steps: detecting data information of fruit tree pests; tracking the fruit tree pests based on the detected data information to obtain a sample image of the fruit tree pests; establishing an improved fruit tree pest detection and identification model; and performing multi-feature extraction on the sample image by using the improved fruit tree pest detection and recognition model to obtain a fruit tree pest recognition result. According to the invention, the problems of low detection precision, large memory occupation, slow reasoning speed and the like of a pest recognition model carried by orchard plant protection equipment at present are solved. 本发明公开了一种基于图像识别的果树害虫识别方法及系统，其中方法包括以下步骤：对果树害虫的数据信息进行探测；基于探测的数据信息对果树害虫进行追踪，获得果树害虫的样本图像；建立改进的果树害虫检测识别模型；利用所述改进的果树害虫检测识别模型，对所述样本图像进行多特征提取，获得果树害虫的识别结果。本发明解决目前果园植保装备搭载的虫害识别模型存在着检测精度低、内存占用大、推理速度慢等问题。
