Hollow recognition method and device based on neural network, storage medium and terminal

The invention discloses a hollow recognition method and device based on a neural network, a storage medium and a terminal, and the method comprises the steps: providing a training set and a test set,wherein the training set comprises a plurality of hollow training pictures containing hollows and a plurality of hollow-free training pictures not containing hollows, aand the test set comprises a plurality of test pictures; segmenting each hollowed-out training picture into a plurality of hollowed-out picture blocks, and segmenting each non-hollowed-out training picture into a plurality of non-hollowed-out picture blocks; training a neural network model based on the hollowed-out picture blocks and the non-hollowed-out picture blocks; performing a hollow recognition test on the test picture byusing the neural network model, wherein the neural network model comprises a convolution layer, a pooling layer, an activation layer and a 1 * N output layer. According to the invention, the identification accuracy and effici
