摘要
设计了基于倾斜摄影技术的煤矿地区土地利用动态变化预测系统,有效预测煤矿地区土地利用动态变化,为煤矿地区土地合理利用与管理提供可靠参考依据。利用无人机倾斜摄影技术采集煤矿地区土地利用相关数据,对土地利用动态变化预测数据执行单独存储操作,调用各类地图与土地利用变化数据库数据,将其传输到土地动态预测中心,通过采集土地利用图像的增强去噪、畸变纠正后,生成并存储土地利用DSM图像,经DSM数据中相对应的土地高程值提取,实现土地利用动态变化预测。实验结果表明,该系统可有效预测煤矿地区土地利用的动态变化,满足实际煤矿区土地利用动态变化预测工作需要;图像增强及畸变纠正后,图像色彩、光线、饱和度以及清晰度均有所提升,且不再倾斜。
A dynamic change prediction system of land use in coal mine area based on tilt photography technology was designed to effectively predict the dynamic change of land use in coal mine area,so as to provide a reliable reference basis for rational land use and management in coal mine area.The UAV tilt photography technology was used to collect land use related data in coal mining areas,perform separate storage operations on land use dynamic change prediction data,call various maps and land use change database data,and transmit them to the land dynamic prediction center.After the enhancement,denoising and distortion correction of land use images were collected,land use DSM images were generated and stored.The dynamic change prediction of land use was realized by extracting the corresponding land elevation value in DSM data.The experimental results showed that the system can effectively predict the dynamic change of land use in coal mining areas and meet the needs of land use dynamic change prediction in actual coal mining areas;after image enhancement and distortion correction,the image color,light,saturation and clarity are improved without tilting.
