相机屏幕坐标为(Xc,Yc),则相机的坐标(Xc,Yc,Zc)和二维码坐标(t,Yt,Tt)可以表示为等式7。 其中P是透视变换矩阵,f是焦距,Sx是X轴方向上的比例因子,Sy是在Y轴方向上的比例因子(Xo,Yo)是相机坐标Z轴通过的坐标,C是由P和T组合得到的变换矩阵Tct。因为存在很对对(Xc,Yc)和(Xt,Yt,Zt),已通过上述程序得到...
augmented realityMarker based tracking requires complicated preparation work that impedes its use in augmented reality applications. This paper presents a novel tracking scheme to be used in an indoor unknown scene by adapting simultaneous localization and mapping (SLAM) algorithms. An infrared (IR) ...
The present invention relates to a marker tracking method in a marker tracking system for tracking a marker in augmented reality, and includes a marker information generation step for generating marker information necessary for estimating the posture of the marker, and a marker posture estimation step...
