摘要
通过在标志物引入代码区及直观的图像信息,设计了一种新的标志物系统,该标志物系统与ARtoolkit等系统相比具有更加形象、识别更加准确的特点;针对标志物设计的特点,提出了一种新的跟踪算法,该算法采用基于角点和纹理的混合跟踪方式,解决了标志物在快速运动或被部分遮挡等情况下的跟踪问题。实验结果表明该标志物系统及其跟踪算法是稳定有效的。
A new kind of fiducial marker was described which consists of a square outline with code region and visualpicture in the interior. Compared with other fiducial marker sysytems, such as ARtoolkit, etc, this system is more usable and accurate Based on the feature of the fiducial marker, a new algorithm for fiducial marker tracking was proposed. Robust tracking was obtained by combining comer amd texture information. Experiment result shows the marker system and the tracking algorithm are stable and effective.
