二维码内容识别的增强现实与实现技术研究

Research on Augmented Reality Based on Two-dimension Code Content Recognition

针对传统二维码内容识别过程中易受标志物的影响而造成识别速度慢的缺陷。在移动增强现实实现技术的基础上,提出了一种结合三维模型信息和QR二维码的增强现实技术应用。通过QR码四点交叉实现模型内容位置的定位监测,利用单应性变换矩阵H进行三维注册和QR码跟踪,采用ZXing库中的Decode类OR码进行内容的解读。在QR码定标中,将三维模型存储在网络终端,通过建立URL来读取标志物链接进行服务器端模型下载,避免了标志物过多会限制识别速度。研究结果表明,采用QR码的增强现实实现技术有效提高了对内容标志物的识别速度和精确度,具备较强的抗干扰和纠错能力。

Aiming at the defect that the traditional two-dimensional code content is easy to be affected by the marker in the process of recognition,the identification speed is slow.Based on the implementation technology of mobile enhanced reality,an application of enhanced reality technology combining 3D model information and QR two-dimensional code are proposed.Through QR code four-point crossover,the location monitoring of the model content position is realized,and the three-dimensional registration and QR code tracking are carried out by using the simplex transformation matrix H.In the QR code calibration,the 3D model is stored in the network terminal,and the marker link is read by establishing URL.The end model is downloaded to avoid too many indicators to limit the recognition speed.The experiment results show that the augmented reality implementation technology of QR code can effectively improve the recognition speed and accuracy of content markers,and has strong anti-interference and error correction ability.
