摘要
以数字航空遥感立体像对为基础 ,辅以地面数字近景摄影测量的方法 ,建立城市三维景观模型 .根据遥感像对之间的相互关系建立一个交会模型 ,得到地物点坐标 ,建立数字表面模型 (DSM) ,然后通过纹理映射描述细部 .实践证明 ,这一方法具有精度高和速度快等特点 ,能有效地实现速度和逼真度的兼顾 ,特别是对于大范围区域的三维建模更能显示其优越性 .
The digital photogrammetry method of solid modeling based on remote sensing image pair is introduced.By this method the intersection model can be easily built,and the exact coordinate and digitcal surface modeling(DSM) were gained,lastly texture mapping was realized and the solid model of city was constructed.It is proved that the method of modeling has the characteristics of high precision and speed,and realizes great balance of demand of speed and fidelity.It shows great advantages especially for large areas.
