AI Technical Summary

Technical Problem

Existing technologies are insufficient for intuitive spatial analysis and scheme comparison during the design phase of linear engineering projects such as highways and railways, and cannot accurately demonstrate the effects of future roadbed filling and excavation, resulting in inaccurate designs.

Method used

By acquiring ground DOM and DEM data, spatial registration and data overlay are performed. Combined with roadbed parameters and route information, simulated orthophotos and digital elevation models are generated, enabling accurate determination and data updating of the roadbed range, and generating highly realistic simulation models.

Benefits of technology

It enables automated generation of simulation results from design, supports construction plan preview and rapid response to design changes, and provides data support for engineering design optimization, accurate earthwork calculation and environmental impact visualization assessment.

Abstract

本发明涉及遥感影像技术领域,具体涉及一种生成路基仿真正射影像和数字高程模型的方法,包括以下步骤:获取地面原始的DOM与DEM数据并叠加构建多通道栅格数据;根据线路和路基参数基于预设步长检索目标坐标点,判定其落入路面或边坡范围,并根据判定结果更新栅格数据;检索缺漏坐标点并补录数据,遍历所述多通道栅格数据,判断任一像素点是否满足缺漏条件,并按相应插值公式补录多通道栅格数据;最后根据更新的多通道栅格数据,结合原始地面DOM与DEM头文件生成仿真图。该发明能够快速响应设计变更,为工程设计优化、施工方案模拟等评估提供了强有力的数据支撑,有效克服了现有技术中成果真实性差、制作效率低、更新繁琐的缺陷。
