Research on 3D reconstruction and application of open-pit mines real-scene based on multi-source low-altitude remote sensing fusion technology
Low-altitude remote sensing fusion technology is a comprehensive technology that combines multiple sensors and data process-ing techniques,possessing the advantages of high resolution,real-time performance,and penetration,and has significant advantages in the application of open-pit mines.Compared to traditional techniques,although they can also provide relatively accurate geological infor-mation,they have a longer data acquisition cycle and cannot meet the timeliness requirements of modem mine production.The applica-tion methods and effects of low-altitude remote sensing data fusion in the construction of real-scene 3 D models were described,the basic principles and methods of low-altitude remote sensing data fusion were introduced,the application effect of low-altitude remote sensing data fusion in real-scene 3D models through experiments was verified,and it was evaluated from the aspects of data accuracy and visual effects of real scene models.The experimental results indicate that low-altitude remote sensing data fusion can effectively improve the accuracy and integrity of real-scene 3D models.Finally,the volume of rock excavation in the mining area is calculated based on the 3D model.
