Provided in the embodiments of the present application are a material counting method, a material positioning method, and an apparatus. A sample image comprises a plurality of materials and the areas where the materials are located are labeled, and the size of an area can reflect the size of a material to a certain extent. Therefore, size features are added in a training process, enabling a target material detection model to be compatible with materials of different sizes. Moreover, since the labeled areas do not overlap each other, the target material detection model can learn how to distinguish materials and gaps between the materials in the training process. Therefore, in an obtained confidence map, the materials have a higher level of confidence, while the gaps between the materials have a lower level of confidence, and thus each connected component formed by pixel points with pixel values greater than a confidence threshold value in the confidence map can be regarded as the area where one material is located, that is, the number of connected components is the number of materials. Therefore, the possibility of mistakenly recognizing a plurality of materials as one material can be effectively reduced, and thus the accuracy of counting is further improved.
