Crop planting management method and management system based on three-dimensional digital twinning

The invention relates to a crop planting management method and management system based on three-dimensional digital twinning. The method comprises the following steps: marking a problem region in a three-dimensional model generated based on three-dimensional digital twinning; acquiring an image of the problem area before the occurrence time period of the problem area; identifying and separating feature objects in the image and decomposing the feature objects; putting the sub-feature objects of the same type into a primary comparison group; analyzing the primary comparison group and then endowing the sub-feature objects in the primary comparison group with numerical values; and counting the total numerical value of each feature object, and marking the feature object with the total numerical value greater than or equal to a set value or a set proportion as a suspected feature object. According to the crop planting management method and management system based on the three-dimensional digital twinning disclosed
