基于ARToolKit的二维码多标识增强现实系统

An 2D-barcode multi-marker augmented reality system based on ARToolKit

为了改善传统增强现实系统模型位姿信息稳定性低、计算耗时较长的问题,运用支持二维码跟踪识别的类库ARToolKit,结合跨平台图形开发包OpenSceneGraph(OSG),开发了二维码多标识增强现实系统的原型系统,并给出了系统实现结果。通过人为控制渲染顺序和图像叠加顺序实现了虚拟物体和实物图像的相互遮挡;通过多标识注册定位保证了虚拟物体视觉上的稳定性;采用二维码作为贴标时,计算实时性好,当贴标达60个时,在1080P分辨率下的帧率仍可以达到28fps。

In order to improve the stability and computational efficiency of pose calculation in traditional augmented reality（ AR） system,it develops an AR system and proposes the effect. It uses ARToolKit to support 2D-barcode markers tracking,applies a cross-platform graphics development package OpenSceneGraph for graphics rendering. Through the artificial control of the order of rendering and image stacking order,it obtains the occlusion between virtual object and actual object. Based on the multi-identification registration,it shows the visual stability of the virtual object. The 2D-barcode multi-marker can reach 28 fps at the frame rate of the 60 markers and 1080 P,and result shows a good real-time performance.
