Abstract: The recognition methods and technologies of common diseases were reviewed from four aspects, image acquisition, image processing, feature extraction and classification recognition. The basic principles, key technologies, implementation methods and application effects of some typical methods were analyzed. The problems and shortcomings of existing research in this field were summarized. The future development trends and research directions were prospected. Using computer vision technology to identify crop pests and diseases has the characteristics of nondestructive, rapid, real-time and accurate, which has a profound impact on accelerating agricultural modernization and improving production efficiency. With the rapid development of mobile communication technology, big data, internet of things, artificial intelligence and remote sensing technology, intelligent recognition and prevention of large area crop diseases and insect pests in natural environment with wide universality, strong stability, high accuracy and strong real-time performance, and standardized processing of mass data of diseases and insect pests are important research directions in the future.

Key words: rice disease, recognition of images, computer vision technology
