Crop pest intelligent identification method

Abstract

The invention belongs to the technical field of disease and insect pest identification, and discloses a crop disease and insect pest intelligent identification method. The method comprises the steps:S1, setting a region range, and obtaining basic information of crops in multiple time periods in the region range; S2, acquiring image data and meteorological data in a regional range; S3, acquiring first feature information reflecting the physiological features of the crops from the image data; S4, judging whether the physiological characteristics of the crops in the area range are normal or notin the current time period, and if yes, ending the process; if not, entering the step S5; S5, identifying a suspected area with abnormal physiological features, and generating a crop resource image; S6, acquiring second feature information reflecting the physiological features of the crops; S7, comparing and judging whether the physiological characteristics of the crops in the suspected area are normal or not, and if yes, ending the process; if not, entering the step S8; and S8, making the final judgment manually. The method is low in cost and accurate in judgment.

[0003] In recent years, the scale of protected planting in my country has been increasing. In the surrounding areas of large and medium-sized cities, protected planting has become the main cultivation mode of vegetables, fruits and flowers. Due to the low temperature and high humidity in the shed, insufficient sunlight, and relatively fixed soil positions, diseased host plants perennial There are other reasons. The occurrence of facility planting diseases has the characteristics of fast flow, heavy damage, long-term damage, and large losses. Especially with the increase of greenhouse cultivation years, p
