According to the soybean seedling emergence uniformity judgment method and system, deep fusion is performed on an improved convolutional neural network algorithm and an image processing algorithm, a model structure and parameters suitable for performing various detections on soybeans are designed according to soybean image features, and the method for judging the soybean seedling emergence uniformity is established. Multiple channels are introduced into a feature extraction network to extract significant features of soybean colors and textures, and the extracted feature information is fully fused, so that the soybean seedling emergence uniformity judgment method can automatically detect the soybean seedling emergence number and divide the soybean growth period, thereby calculating the seedling emergence ratio in each period, and improving the soybean seedling emergence uniformity. And the judgment of the seedling emergence uniformity is realized. A perception layer, a transmission layer ...
