Object-oriented Open Pit Extraction based on Convolutional Neural Network

The overexploitation of mineral resources will have a serious negative impact on the natural environment. The monitoring of the mine environment is of great significance to the construction of ecological civilization. Machine learning algorithms have been widely used in traditional mine monitoring and have achieved good results. In recent years， with the rapid development of the field of deep learning， relevant theoretical knowledge has gradually been applied to remote sensing image processing. In this study， the deep learning algorithm is combined with the object-oriented method， and the GF-2 image is used to extract the land occupation type by applying the conventional neural network from the mining area in Yuzhou City， Henan Province. To compare the performance of the proposed methods， the support vector machine method was used. The results show that the overall accuracy of the convolutional neural network is 91.85% and the kappa coefficient is 0.90， which is higher than the support vector machine method. This paper shows the advantages and feasibility of this method in the extraction of open-pit mining areas and provides reliable technical support for the scientific management and environmental monitoring of open-pit mining areas.
