简介:基准的标记基于的扩充现实有许多应用。到目前为止,基准的标记的内部模式总是被用来编码标记。因此,基准的标记图象的大部分被用于编码而不是为姿势精确性提供相应特征点。这篇论文论述直接利用的一个新奇方法射影不变在相应特征点的位置的关系包含了编码标记。建议方法不为再编码要求模式图象的区域并且能提供更多的相应特征点以便更高的姿势精确性能容易被完成。象累积分布函数,设计确认和柔韧的过程那样的许多相关途径被建议克服敏感的问题射影不变。建议基准的标记系统可靠、柔韧的试验性的结果表演,和罐头比由存在基准的标记系统完成了提供更高的姿势精确性。电子增补材料这篇文章(doi:10.1007/s11390-007-9100-0)的联机版本包含增补材料,它对授权用户可得到。
