本文提出了一种基于球体的校准方法,适用于具有不受约束的一台投影仪和一台相机的结构光系统,无论模式编码如何。还提出并测试了这种方法的 1-pose 示例。与传统的 15 个姿势的平面平移方法相比,我们注意到一致性提高了 10% 以上,同时校准时间缩短至 6%,并且校准配件缩小到手电筒大小。这种方法非常适合以移动性、速度和易用性为重要标准的应用。
This paper proposes a sphere-based calibration method for the structured light system with unconstrained one projector & one camera, regardless of pattern codification. A 1-pose example of such a method is also proposed and tested. In comparison with a traditional plane translation method of 15 poses, we note an increase in the consistency of more than 10% while the calibration time shrinks to 6% and the calibration accessory is reduced to the size of a flash-light. This method suits well for applications where mobility, speed and ease-of-use are important criteria.
