| 摘 要： | 改进的蜘蛛网格建模算法,对具有明显几何特征的长通道型场景建模,可以通过用户指定原始图像中的灭点、内矩形和四条放射线形成不等边盒状模型,利用投影几何原理并经过简单地计算既可产生逼真的三维场景.实验结果表明:该算法弥补了TIP模型在实现长通道型场景绘制中的不足,提高了图像绘制和漫游的有效性.

| Abstract: | The improved spider mesh modeling algorithm brought out in this paper is very effective when model the long channel-like scene which has obvious geometric characteristics.By means of it through the user the vanish point,inner rectangle and four radiation lines in source image to get the non-equality box model can be appinted,then the projective geometric principal to process the model can be utilized,the living 3D scene can be obtained.The experiment result shows that,this algorithm remedies the disadvantage of TIP modeling in the long channel-like scene rendering,also improves the validity of image rendering and scene tour. |
