The study on intelligent network video 3D dynamic supervision and early warning technology of open-pit mines is the key to realize real-time and accurate management of mineral resources and reserves utilization,and is an important basic work of mine administration and management.The intelligent network video monitoring technology is introduced into the field of mineral resources supervision in open-pit mines,and a rotating dual-camera video image 3D mine modeling method is pro-posed.The method uses collinear equation and Brown model to realize high precision camera calibration.By means of relative orientation,model connection,approximate absolute orientation and free net beam method adjustment,automatic orientation of time sequence image is realized.Finally,the mine three-dimensional modeling is realized through SGM dense matching and three-dimensional point cloud network.The application results show that the proposed method can meet the accuracy require-ments of dynamic monitoring of mine reserves,realize real-time monitoring of mineral resources,improve the efficiency of min-eral resources supervision,and provide theoretical basis and technical support for the construction of dynamic monitoring system of mineral resources.
