摘要
提出了一种联合下视影像与倾斜影像基于整体矢量遮蔽区域纹理补偿方法。首先利用建筑物数字模型整体投影建筑物遮蔽区域检测方法得到传统正射影像上遮蔽区域,然后根据遮蔽区域与周边建筑物成像关系自动选择最优纹理补偿影像,最后对遮蔽区域进行纹理补偿。试验表明,本文方法能够有效地从倾斜影像中找到最优纹理补偿影像,制作出了高质量的真正射影像。
A method for texture repair of occlusion areas in true orthophoto map generation based on the vector of occlusion area combined the lower image and oblique image was proposed. Firstly,the occlusion areas on traditional DOM were obtained with the method of overall projection of DBM for occlusion detection. Secondly,the best auxiliaryimage was automatically selected according to the relationships between the occlusion area and the surrounding buildings. Finally,the occlusion areas were repaired. Experiments show that this method proposed in this paper can select the best texture compensation image from the oblique images effectively,and the high-quality true orthophoto map was generated.
