低空遥感融合技术是一种结合了多种传感器和数据处理技术的综合性技术,具有获取高分辨率、实时性和穿透性的优势,在露天矿中的应用具有显著优势。相比之,传统技术虽然也可以提供较为准确的地质信息,但数据获取周期较长,无法满足现代矿山生产的及时性需求。讲述了低空遥感数据融合在实景三维模型构建中的应用方法和效果,介绍了低空遥感数据融合的基本原理和方法,通过实验验证了低空遥感数据融合在实景三维模型中的应用效果,并从数据精度和实景模型视觉效果方面进行了评估。实验结果表明,低空遥感数据融合可以有效提高实景三维模型的精度和完整性。最后根据三维模型计算出采矿区挖石方量体积。

Low-altitude remote sensing fusion technology is a comprehensive technology that combines multiple sensors and data processing 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 information,they have a longer data acquisition cycle and cannot meet the timeliness requirements of modern mine production.The application methods and effects of low-altitude remote sensing data fusion in the construction of real-scene 3D 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.
