【摘要】：基于标志的跟踪注册技术是当前增强现实系统中最成熟和最接近实际应用的注册技术。该注册技术是将一些已知空间相对位置的人工标志放置在需要注册的真实场景中,利用摄像机跟踪识别标志。以手部康复训练为背景,提出了一种特殊的近景手持彩色标志及其识别方法。标志采用海明码编码技术编/解码,不仅扩充了标志的编码量,还能够利用海明码的奇偶校验方法解决由于手部无意遮挡引起的跟踪注册失败问题。实验结果表明,该彩色标志在多种环境下都能够实现稳定注册,具有一定的鲁棒性。为验证彩色标志的实用性,提出一个基于手部运动的增强现实桌面击球游戏,拥有较好的注册效果。彩色标志的提出将有助于增强现实手部康复训练项目的研究。
[Abstract]:Tag-based tracking registration technology is the most mature and close to practical application registration technology in the current augmented reality system. In this registration technique, some artificial signs of relative position of known space are placed in the real scene where registration is required, and the camera is used to track and identify the signs. Based on hand rehabilitation training, a special close range handheld color sign and its recognition method are presented. The symbol is coded / decoded by the Hemming code, which not only expands the coding quantity of the symbol, but also solves the problem of tracking registration failure caused by the unintentional occlusion of the hand by using the parity check method of the Hemming code. The experimental results show that the color symbol can be registered stably in many environments and has a certain robustness. In order to verify the practicability of color logo, an augmented reality desktop batting game based on hand movement is proposed, which has good registration effect. The proposal of color sign will be helpful to the research of hand rehabilitation training project.
