Soil information detection method and device and drought and flood degree determination method and device

The invention discloses a soil information detection method and device and a drought and flood degree determination method and device, and relates to the technical field of deep learning. The soil information detection method comprises the following steps: determining an underground land section image of a to-be-detected target land area; and analyzing the underground land section image by using the soil detection model to obtain underground soil information of the to-be-detected target land area, the underground soil information including soil humidity information. According to the method, tedious operations such as acquisition, weighing and calibration are not needed, manual participation is less, after the underground land section image is determined, the underground soil information including the soil humidity information is obtained through analysis of the soil detection model, and the method is not only timely and efficient, but also suitable for large-area land (such as farmland) scenes. 本申请披露了一种土壤信息检测
