随着三维城市等新兴技术发展，真正射影像图需求也日益明显。传统正射影像图并未考虑如人工建筑物等空间目标，从而导致这些目标的中心投影变形依然存在，势必导致数字正摄影像(DOM)中出现建筑物倾斜、遮挡等问题。据此，总结了一种利用数字建筑物模型(DBM)数据进行真正射数据的处理方法。真正射影像重建的结果表明：应用本方法进行三维城市模型重建具有自动化程度高、效果逼真、成本低的特点，为快速、大面积的城市真三维模型纹理迅速重建提供了一种有效途径。%With the development of digital three dimensional city emerging technologies,the demands of true orthophoto map increasing obviously.Traditional orthophoto map did not consider some space targets such as spatial artificial buildings,which results the deformation of central proj ection of these goals existing,and will inevitably lead to some issues such as building tilt, shelter and others in document obj ect model (DOM).A special method to deal with true orthophoto data by digital building model (DBM)is summarized.The result shows that,to reconstruct three dimensional urban models,this method have the characteristics of high automation,realistic effect,and low cost,which could provide an effective way for the texture of true three dimensional large urban models quickly.
