Remote sensing image target detection method and device

Abstract

The invention relates to a remote sensing image target detection method and device. The method comprises the following steps: firstly, establishing a depth full-convolution neural network; the depth full-convolution neural network comprises a main network used for feature extraction and a sub-network used for target detection; training the main network through an image classification database; after the main network is trained, adding the sub-network; fine-adjusting the network parameters by means of the remote sensing target detection database to obtain a trained depth full-convolution neuralnetwork; and finally inputting the remote sensing image to be detected into the depth full-convolution neural network to obtain a final target detection result. Compared with a conventional way of directly using a remote sensing target detection database to train the established depth all-convolution neural network, the generalization ability and accuracy can be improved, and the rapid, high-precision and high-robustness automatic target detection can be realized in a complex background.
