摘要 给出了一种使用手持相机拍摄的多幅图像构造可见外壳的方法 ,该方法无需对相机运动方式作任何限定 ,而是利用多幅图像上的对应特征点求出每一幅图像的拍摄方位 ,因而可以非常灵活地获取某些较大规模的室外场景的几何模型 实验结果表明 ,利用该方法生成的可见外壳模型准确真实 。 In this paper, multiple images acquired with a hand-held camera are used to generate visual hull models The camera can be freely moved while taking the images, and the corresponding image features are further used to determine the position of the camera Consequently, realistic models of large-scale outdoor scenes can be obtained with our method Practice shows that the results are correct and reliable so as to meet the requirements of virtual reality applications
