The invention relates to a duck egg identifying and positioning method. Feather, straw, silt or other materials are used for simulating the complex environment of the duck shed, a camera is used for shooting, and obtained data comprise duck egg images of multiple angles, multiple positions, different distances and different shielding forms; the method comprises the following steps of: dividing collected original image data into a training set, a verification set and a test set according to 6: 2: 2, and enhancing sample data of the training set in order to enrich data information of the existing training set and prevent an overfitting problem of a model; establishing a YOLOV7 target detection model to detect the data; improving and training the model, and establishing an optimized model; and identifying and positioning the duck eggs by adopting the optimized model. According to the method, the optimal detection model YOLOV7CDS is obtained by improving and training the YOLOV7 model, the F1 fraction of the optim
