摘要： 针对人造物体场景的特点,用人机交互的方法标出物体的平行线和特征点,利用灭点计算出相机的内部参数,进一步计算出旋转矩阵。再根据物体的几何约束关系,得到平移向量和物体模型的空间信息。然后从图像中提取纹理,经过变换后,映射到模型上去,使之具有相片般的真实感,并能够进行实时漫游。

Abstract: This paper presents a modeling way from a single image.based on vanishing points.According to the characteristics of artificial objects,we can mark and determine the object’s parallel lines and characteristic points manually.By using the vanishing points,the camera’s interior parameters can be worked out and the rotation matrix.be calculated.According to geometric restriction of the objects,it can obtain the translation vector and spatial information of the object’s model.After extracting and rectifying the texture from image,it can be mapped to the model which would have photo-realistic and can be walk through at random.
