摘要

本文介绍了一种光学跟踪系统的原型，该系统运行在未改装的带有立体摄像头的HTC Evo 3D手机上。该系统使用棋盘标记对捕获的场景进行三维度量重建。我们展示了相机校准的结果，并通过比较从系统获得的三维点集和参考几何形状来评估跟踪的准确性。原型的准确性很大程度上取决于与相机的距离。在0.35 ~ 1.15 m距离范围内计算的912个点的三维重建的均方根误差为7.4 mm。

Sparse 3D reconstruction on a mobile phone with stereo camera for close-range optical tracking

We present a prototype of optical tracking system running on unmodified HTC Evo 3D mobile phone with stereo camera. The system uses checkerboard markers for 3D metric reconstruction of the captured scene. We present the results of camera calibration and we assess the accuracy of tracking, by comparing the 3D point sets obtained from the system with a reference geometry. The accuracy of the prototype turns out to be strongly dependent on the distance from the cameras. The RMS error of 3-dimensional reconstruction of the set of 912 points computed within the distance range of 0.35-1.15 m is 7.4 mm.
