Abstract:
随着虚拟现实技术的发展,对物体进行快速有效建模逐渐成为了研究热点。基于图像建模技术是一种有效的建模方法,其最大的优点是可以利用图像中的信息直接建立物体的几何模型,并且可以迅速构建出具有“照片级”真实感的3维模型。常规的方法是先求解摄像机内外参数,再求解空间中各点在世界坐标系下的位置。提出了一种基于两幅图像利用灭点性质进行建模的新方法。该方法首先利用灭点属性推导出了相机中心在世界坐标系下的坐标位置的解析表达式,再利用两幅图像之间的空间几何约束关系,从空间约束关系中反算出物体各点的空间位置从而重建出物体几何模型,最后进行纹理映射。在物体重建的过程中只利用到了相机内参数,而跳过了对相机外参数的标定,实验结果表明,该方法简单可靠,可用于实现对拥有规则表面的物体3维重建。
