摘要: 三维遥感机理模型是开展定量遥感反演教学和新方法试验的重要工具。介绍全波段多传感器三维遥感机理模型RAPID的原理、输入输出和常见应用方法。RAPID模型基于辐射度(Radiosity)理论和计算机图形学算法,提出了针对植被的孔隙面元(Porous individual object)概念,大幅降低三维辐射传输的计算量;并将模拟能力扩展到光学、热红外和微波波段,实现反射率、亮度温度、点云、波形和后向散射系数的统一模拟。RAPID非常适合定量遥感教学、简单模型验证、复杂场景模拟和多源数据融合探索。全面介绍全波段多传感器三维遥感机理模型RAPID的原理、输入输出和常见应用方法。 关键词: RAPID;  辐射度;  三维辐射传输;  全波段;  统一模型     Abstract: Three-dimensional (3D) remote sensing mechanism model is an important tool for teaching quantitative remote sensing inversion and conducting virtual experiments on new methods. Based on Radiosity theory and computer graphics algorithms, the RAPID model proposed the concept of porous individual object for vegetation, which greatly reduced the calculation of 3D radiation transfer. The simulation ability of RAPID has been extended from optical, thermal infrared to microwave bands to achieve the unified simulation of reflectivity, brightness temperature, point cloud, waveform and backscattering coefficient. RAPID is very suitable for quantitative remote sensing teaching, simple model validation, complex scene simulation and multi-source data fusion exploration. This paper generally introduced the principle, input and output as well as common application methods of RAPID, the full-band and multi-sensor 3D remote sensing mechanism model.
