3D建筑重建的纹理提取与映射方法的实现

以往通过采集图片中建筑物平面上的纹理构建场景的方法,大部分都是半自动完成的。针对此问题,提出了一种解决方法,即:通过校正输入图像,融合透视图提取纹理图片,对纹理图像进行校正,消除透视扭曲,通过补偿光源颜色估计纹理色彩。仿真实验结果表明,该方法避免了3D测量的中间过程,较好地解决了拍摄过程中的相关问题如不均匀光源、高光以及遮挡灯。

3D building reconstruction texture extraction and mapping implementation

The past through the picture collection of buildings in plane texture construction method in the scene, and most of them are semi-automatic completed. According to this problem, the authors put forward a kind of solution method--By correcting the input image, fusion perspective texture images, a new method to eliminate the perspective distortion, texture image correction was proposed, through compensation of illuminant color estimation texture color. By the simulation experiment, The results show that the method avoids 3D measurement process, can solve the shooting process related issues such as uniform source of light, high light and shade lamp.
