Sample collection and detection method and device and storage medium

The invention discloses a sample collection and detection method and device, and a storage medium. The method comprises the following steps: collecting an original image in a to-be-detected region; extracting a detection target in the original image to obtain a plurality of target features; classifying the target features, and performing division in the original image according to the classified target features through bounding boxes of different colors to obtain a plurality of first classification sample images; identifying the first classification sample graph, and modifying the first classification sample graph with classification errors to obtain a modified feature graph; and outputting the unmodified first classification sample graph and the modified feature graph as classification detection results. According to the method, the labor cost can be effectively saved, errors brought by manual operation can be effectively reduced, the sampling detection efficiency is high, the quality is good, classification
